The Sixties brought us drugs, protests, and paneling. The Seventies let these things endure, grow and become a classic. Today everyone is flying through grade school, junior high, and high school with some kind of over the counter drug of some sort. But building materials took a turn when people began to use gypsum instead of paneling to brighten up their homes and offices. Paneling was great if one was trying to create some kind of log cabin in the suburbs. The outside of their home looked like every other house on the block but the inside looked as if the woods were in the room. Gypsum ended all of that. Gypsum is a mineral that was taken from our dear mother earth and pressed between two sheets of paper for use in the construction of new houses and referred to as sheetrock. Paneling was replaced by drywall (sheetrock) and building was never the same again after that. Drywall was invented in the early 1900's but never really took off until the hippies were getting tired Governmental acid. Somewhere in the Eighties, Gypsum had surpassed paneling as the number one wall material and still is to this day. I've spent years working while going to school and construction was what paved the way to greener pastures. As a contractor I've carried, ordered, screwed in place, mudded over, textured, and painted miles of Gypsum. Gypsum is a lot like Anhydrite. They have the same chemical composition but Gypsum bends a little bit and has water inside; Anhydrite has no water. This is one of the reasons that it works so well in construction. There is a very interesting kind of Gypsum called Enhydros. Enhydros have water trapped inside of them. When you pick up an Enhydro you can see a little bubble floating around in it when you shake it. This kind of Gypsum is very rare and sought after by collectors. Sometimes sand gets caught inside the Gypsum crystals like water does. The…...

Mineral Resource

...DEVELOPMENT OF NATURAL RESOURCES OF BALOCHISTAN Introduction Balochistan is the largest province of Pakistan with 44 percent landmass of the country but has 5.6 percent of the population. The province which is almost half of the country’s land mass has been receiving least attention by successive governments since independence. Therefore the huge potentials of this province to become a strong economical hub could not be exploited and till today it remains the poorest of all four provinces. Apparently a barren province from agriculture point of view is rich in its natural resources. Huge reserves of mineral deposits, gas, oil and long sea shore makes this province extremely attractive at regional as well as at international level. The absence of basic development infrastructure and effective strategy coupled with backwardness, scant population base, rugged terrain exploited by sub nationalist leaders and sardars continue to undermine the progress and socio economic development of the area. Aim To carry out an indepth analysis of vast potential of natural resources in Balochistan with a view to suggesting a pragmatic natural resource development strategy for the province. Scope The paper will be developed in the following sequence:- a. Part I: Balochistan – Some Facts. b. Part II: Natural Resources – Potentials and Constraints. c. Part III: Recommendations. d. Concl.

Metamorphic Rocks

...Metamorphic Rocks University Of Phoenix By: Laurea Pruitt August 29, 2010 Where do metamorphic rocks originate? Metamorphic rock is produced from pre-existing rock that is altered, but not melted by heat and pressure deep below the earth's surface. Common metamorphic rocks include marble, which forms from limestone, and slate from shale or mudstone. If the pressure and heat increase to the point where the rock melts, magma forms to produce new igneous rock. They originate from non-metamorphic rocks which get changed in some way; for example through pressure and temperature. Typically rocks that form near surface undergo progressive burial or seduction, exposing rocks to higher temperature and/or pressure conditions than they saw at formation. The changes in pressure and temperature cause the minerals to deform and recrystallize, and even involves changes in bulk chemistry addition or removal of chemical constituents like water and carbon dioxide. When you find metamorphic rocks at the surface of the earth, that means that either a lot of rock has eroded, exposing the rocks that were once much deeper in the crust, or there has been some really significant fault movement that has brought the rocks from deep in the crust toward the surface. Metamorphic rocks are formed from Igneous or sedimentary or both type of rocks due to excessive heat. The rocks first change their shape and size and then due to pressure, they become metamorphic rocks, Most metamorphic rock......

...situations. For example, minerals. Did we know that we use minerals in our everyday activities? Without them, there would be no cars, trains or planes. I wouldn’t be able to clean my teeth or wash my clothes. Clocks, watches and jewelry, tin cans and aluminum foil - all minerals! And of course, I wouldn't be sitting down, looking at a computer, and making and reading this now if it weren't for minerals. Where would I be without light bulbs? If tungsten in light bulbs are omitted? How can I write without a paper which is made up of minerals? How can I put pen to paper without minerals? How can a house or school be beautified without minerals that are used in making ceramic flower pots? How I can draw the things I view on a microscope in our Anatomy and Physiology using a pencil without minerals? Minerals are important to humans. Mineral resources in the form of metallic and nonmetallic are both used in different ways, in such a way these metals are used for making machines, roads and buildings, computer chips, ceramics, electric circuits; and diamonds and corundum for abrasives and jewelry. Can you picture a world without rocks and minerals? If there were no rocks there would be no food, toothpaste, pencils, silverware, plates, makeup, statues and so much more. If there were no rocks we wouldn't have soil for food. Soil is made mostly of rock pieces and minerals. There would be no tools, no shelter, no jewelry, no food, and no roads, not much left. We use rocks in medicine......

Mineral Based Industry

...called mineral based industries. Mining is the extraction of valuable minerals or other geological materials from the earth, from an orebody, lode, vein, (coal) seam or reef, which forms the mineralized horizon and package of economic interest to the miner. To gain access to the mineralised package within the lease area (aka Mining Rights Lease) it is often necessary to mine through (to create access, shafts, addits, ramps) or remove to the side waste material which is not of immediate interest to the miner. The total movement of ore and waste, which also includes the removal of soil in some cases, is referred to as the mining process. Depending on the nature, attitude, and grade of the orebody, it is often the case that more waste than ore is mined during the course of the life of a mine. The waste removal and placement is a major cost to the mining operator and to facilitate detailed planning the detailed geological and mineralisation characterization of the waste material forms an essential part of the geological exploration programme. The science of extractive metallurgy is a specialized area in the science of metallurgy that studies the extraction of valuable metals from their ores, especially through chemical or mechanical means. Mineral processing (or mineral dressing) is a specialized area in the science of metallurgy that studies the mechanical means of crushing, grinding, and washing that enable the separation (extractive metallurgy) of valuable metals or minerals......

Ingenious Rocks

... AND METAMORPHIC ROCKS Rocks are in order to make it easier on people to confirm them in the future. This can be done in a numerous ways. Each rock type has their own specific ways, but there are two different aspect that apply to all. The particular and composition. These two, before with some others help to classify igneous, sedimentary, and metamorphic rocks. The First Group is Igneous rocks are historical first by construction. This is broken down mainly into grain size. First there are intrusive, or plutonic igneous rocks. These types of rocks cool within the crust and form large, visible crystals. The opposite would be extrusive, or volcanic rocks. “These rocks are characterized as either extrusive or intrusive”. Types of Extrusive Rocks Basalt is normally a dense, dark, massive rocks, high in calcium and iron magnesium- bearing minerals and low in quartz content. Andesite is an extrusive rock intermediate in composition between rhyolite and basalt. Andesite lava is of moderate viscosity and forms thick lava flows and domes. Rhyolite is a felsic extrusive rock. Due to the high silica content, rhyolite lava is very viscous. It flows slowly, like tooth paste squeezed out of a tube, and tends to pile up and form lava domes. Intrusive igneous rocks are made from silica and plagioclase. They tend to be grays and browns in color. And then, felsic rocks are light in color and contains with some amphibole and biotitew. Granite is an igneous rock composed mostly......

Sedimentary Rocks

...All about Sedimentary Rocks Zakk Wylde SCI/245 January 30, 2011 Stephen Hallin The changing plate interactions and shifting plate junctures, helps us to understand the sedimentary basins. Although plate tectonics is mostly about the horizontal movements of the lithosphere, it also involves large vertical movements which accounts for changes of the crust thickness. Thick sedimentation has to have an initial depression or progressive subsidence to proceed; the auxiliary vertical movements are what mostly control the sedimentary basins (how they evolve). Geographic changes related to the governing horizontal movements also affect patterns of sedimentation strongly. Therefore, sedimentation can be viewed as the result of a succession of discrete plate tectonic settings, and plate interactions whose effects blend into a continuum of development. Sedimentary rocks are composed from deposits of material worn away from pre-existing rocks. “The word sedimentary comes from the Latin word sedimentum, which means settling. They come from the cementation of sediments that result from the erosion of older rocks. The characteristic feature of sedimentary rocks is their stratification or layering. Examples of sedimentary rock include; chalk, coal, limestone,......

Mineral

...Joesmithite The Joesmithite mineral was named after Joseph Victor Smith. Joseph Victor Smith was born in 1928 and later died in 2007. As a young boy on his parents farm north of England, Joseph Victor Smith often wondered why part of the moon was white and part of it was black. In Dec of 1969 the question that often pondered his mind as a child began to once again trouble him. He reached a conclusion that the black material was basalt, this is no more than solidified lava. Additionally, Smith reached the verdict that the white color in the moon was rock enriched with feldspar. It was Smith determination the feldspar crystals, being lighter than that of basalt, floated to areas of the moon when part of the planet was melted lava. Joseph Victor Smith endured much criticism for his theory but during an interview in 1999 he noted that his theory of the hot moon had much more effect and support over the theory of cooler models. Smith had an overwhelming concern for our environment and the preservation of the earth. In the 1980’s his concern for threats to the human race presented by the earth (comets, colliding, asteroids and other natural hazards) within a combination of articles and conferences. Smith received the Roebling Medal in 1982 and in 1998 he organized the National Academy of Sciences Colloquium on Geology, Mineralogy, and Human Welfare. Smith documented more than 400 scientific articles that where published in journal such as Science, Nature, Journal of......

Granite Rock

...Individuals curious in locating new life made travels to the West. One individual in particular, Joanne McIntryre, found more than a new home when she came across Enoch Wilson whom she later married. Their son Arthur came along shortly after. In the years proceeding, Arthur attended and graduated from Massachusetts Institute of Technology and later returned to California. His career began as a construction engineer working for Oakland’s Leona Heights Quarry. Across the bay in Santa Cruz, a gentleman by the name of Warren Porter came across potential in the granite quarry located in Aromas. Warren suggested the purchase of the quarry to Arthur who later borrowed $10,000, and moved his entire family to Watsonville where he incorporated Granite Rock Company. Doors first opened for this construction company on February 14, 1900. Labor did not come easy back then as men worked by hand crushing stone to six inch and minus. Horse drawn carriages moved material from one location to another, where rail lines took care of longer distances. Workers dedicated entire lives to this labor, sleeping in bunkhouses, and eating in a cafeteria together before work began each day. Moving forward into today’s time, Graniterock is a highly reputable company ranking in at one of the “100 best companies to work for in America, ” stated by Fortune magazine. Current operations run from Oakland down to Monterey and range from building materials, concrete, environmental research, and more. The......

Sedimentary Rocks

...Sedimentary Rocks Your Name Plate tectonics affect where sediment falls to the way that rocks are formed from the sediment. There are three different types of sediment rocks that are created in a similar manner but actual make up of each sediment rock is very different. There is clastic sediment that will form clastic sedimentary rock, chemical sediment that will form chemical sedimentary rock, and then there is Biogenic sediment that will eventually form Biogenic sedimentary rock. This happens in many different ways and plate tectonics help this process all along the way. “Divergent margins create rift valleys and passive continental margins. Colliding tectonic plates create structural basins and valleys associated with mountain ranges as a result of the folding and faulting of rock. Subducting plates form deep oceanic trenches along with volcanic arcs that may have back-arc basins. All of these locations are effective traps for sediment.” (From Sediment to Sedimentary Rock, 2008). Convergent plate boundaries can usually be found on the edges of high mountain ranges due to plate collisions. When pieces of the mountain breaks off it falls to low-lying areas as gravel and sand. Convergent plate boundaries lie in very low-lying trenches caused by the subduction of plates. The sediment will pile up quickly because these areas are so steep. Once sediment has settled it will then begin the process in becoming a rock. Sediment goes through a process call......

Minerals

...There are only two main functions of minerals in the body, to build body structures, and help with bodily functions. Some minerals are needed in large amounts they are called macroelements (major), others are needed in much smaller doses these are called microelements (trace). Some minerals such as calcium are used to build strong teeth and bones, but also to help in blood clotting and nerve function. The best sources of minerals are fruits, vegetables, nuts, beans, and of all of these green leafy vegetables. We often think red meats are good sources of minerals but some healthy alternatives are sweet potatoes, pumpkin seeds and salmon they have higher concentrations of vitamins and minerals, with less fat, cholesterol and calories. Some minerals are hard to get from fruits or vegetables so to get the most minerals out of the vegetables or fruits some dietitians recommend juicing them. This separates the minerals from the fibers of the plant. Water helps to regulate body temperature, lubricate joints, helps to dissolve nutrients and minerals so that the body can use them. Almost all of the body’s major systems depend on water to function properly; your life depends on water. The average male in good health need around three liters or 13 cups of liquid a day, and the average female in good health need around nine cups per day.(www.mayoclinic.com).
