...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 Geology...

...iI chose to write about the mineral, Kaolinite. Kaolinite, also known as China clay, Kaolin, and White Clay is a very fine mineral. The chemical composition of Kaolinite is Al2Si2O5(OH)4. Kaolinite is used in a variety of materials such as paper, concrete, and paint. Kaolin is used in one of the most important pieces of equipment I have as a medic in the Army, Combat Gauze. Kaolin is impregnated into Quick Clot Combat Gauze and is used to stop massive hemorrhaging in trauma patients. Kaolinite is formed from the weathering of minerals such as Feldspar. Kaolinite can be found on almost every continent with the exception of Antarctica. Kaolinite or Kaolin, gets its name from the Chinese hill from which it was mined for centuries (Kao-Ling). As a raw mineral Kaolinite is virtually worthless, it takes a long list of processes to get the desired material from kaolin and this makes mining for kaolinite and long a carefully chosen procedure. Companies who mine kaolinite drill hundreds of core samples over extremely large areas before giving the go ahead for an actual mine to be constructed. Companies who mine for Kaolin usually have more than one mine because the quality of the kaolinite can vary within a single deposit. Even though Kaolinite is so abundant, I would consider it to be an extremely important mineral as it is important for the manufacturing of such important day to day materials. Ralph, J., & Chan, I. (2014, March 30). Kaolinite. : mineral information and data...

...What is granite made up of? It is a rock, not a mineral, so it is built up of several different minerals, which include; Mica, quartz, hornblende, magnetite, and feldspar. Although some may argue against the inclusion of magnetite and mica I firmly believe that those minerals are some of the most prominent appearing in granite. Mica and quartz are known to be metallic and have a low hardness on the Mohs scale. Both of which were exemplified by our sample of granite. Along with a slight magnetic pull that our granite gave off, implying that the granite included magnetite too. Not to mention the granite is partly grey (A similar shade to hornblende), proving that yet another mineral, hornblende, is included within granite. Feldspar is also...

...Moonstone is a semi-precious Feldspar mineral that is most commonly seen as a white stone with a bluish sheen. Also known as Ceylonese Opal, Girasol, Fish-Eye, Aphroselene, Chandrakanta and Wolf’s-Eye, the moonstone was named after the moon due to the similarities between the moon’s glow and the stone’s adularescence. The adularescence is the blue color sheen that is seen when light is reflected from the stone. Moonstones, though most commonly white, can also be colorless, silver to grey, green, orange, peach, yellow or multi-colored. They can be found in Brazil, Burma, Germany, India, Madagascar, Mexico, Tanzania, and the United States, but the highest quality moonstones come from the region of Sri-Lanka. This stone has been around and prominent since ancient times. Romans thought that the stone was actually formed by the moonlight, while in the Orient it was believed the stone was made up of these rays and the sheen produced by the stone was a sign that a good spirit lived in the stone. A similar belief was held in India and the stone is still considered sacred there today. Their legend...

...Abstract Central Texas contains Precambrian rocks, which were exposed due to the Llano uplift. This paper looks further into the Devil’s Waterhole of Ink’s Lake to get a better understanding of the area. First the geology of the Llano uplift is studied to get a better understanding of how the rocks in the area were formed. The rocks in the area, which consists of Valley Springs Gneiss and Town Mountain Granite, are studied even further to see the composition of each and how each was formed. The Valley Spring Gneiss is split into amphibolite, biotite gneiss, quartz-feldspar gneiss, and quartzite. Each of the five different rock samples were observed and studied in the area to give us a better understanding of their compositions, how they were formed, and what their protoliths are. The Devil’s Waterhole of Ink’s lake is the area of focus in studying Precambrian rock. Throughout the Ink’s Lake region we will take focus on the Precambrian metamorphic rock that was exposed due to the Llano uplift. The Llano uplift contains some of the oldest rocks in North America and is exposed in Ink’s Lake, Texas. This is exposed due to the oceanic-continent collision, which drove the Llano uplift upward. After the weathering away of the younger rock on top, the currently exposed metamorphic rock is more easily observed. Following the Llano uplift exposure, there was an intrusion of the Town Mountain Granite, which we will also look further into. We also observe the areas reactions such as...

...Granite is made up primarily of three minerals: quartz, alkali feldspar (alumina and silica) and plagioclase feldspar (sodium and calcium). Granite may also contain additional minerals such as mica, hornblende and occasionally pyroxene. The Granite texture is very granular, and can come in many different colors ranging from white, pink, light or dark gray. The composition of Granite is felsic and is a very plentiful rock in the Earth's continental crust. The lighter density of the felsic composition lets the granite escape subduction, keeping this rock closer to the surface.https://en.wikipedia.org/wiki/Granite. The Pikes Peak Mountain Range is one home to this Intrusive rock. The Peaks formations that occurred were due to magma that has moved in a upward motion cutting across pre existing rock which creates forms known as plutons...

...Versus All-Ceramic Crowns | | 14 | Conclusion | | 15 | References | | INTRODUCTION The word ceramic is derived from the Greek word keramos which literally means ‘burnt stuff’ but which has come to mean more specifically a material produced by burning or firing. The term ceramic refers to any product made from a non-metallic inorganic material usually processed by firing at a high temperature to achieve desirable properties. This material is opaque, relatively weak and porous and would be unsuitable for dental applications. It consisted mainly of kaolin. The more restrictive term porcelain refers to a specific compositional range of ceramic materials originally made by mixing kaolin (hydrated aluminosilicate), quartz (silica), and feldspars (potassium and sodium aluminosilicates), and firing at high temperature. Dental ceramics for metal-ceramic restorations...

...In addition to the radioactive minerals, there was also found niobium, molybdenum, some rare earths and the very rare and unusual thucholite. Plus a modest amount, (618 tons) of feldspar was harvested in 1925 the year McQuire & Robinson Radium & By Products Co. increased their stake to 50 acres. As for the uraninite mined, a few hundred pounds of it was sent to various museums (an example is ROM #M12500) and sold to collectors due to their high quality. In the end, Harry McQuire applied to the Lieutenant Governor of Ontario to surrender the charter for the McQuire-Robinson Radium and By-Product Limited as of April 1932. Several of the McQuire brother's land claims in the Lawson Bay area fell into tax arrears to be sold off by the government in 1939. Harry did better than his brother spending his later life in the upper class Forest Hill area of Toronto. The discovery of high grade uranium and thorium ores attracted 'rock...

...Associate Level Material Comparison Worksheet Use the following table to compare extrusive and intrusive rocks. Describe and compare each type in at least 150 words. Extrusive Rock Intrusive Rock Extrusive rock refers to igneous volcanic rock formation in which hot magma from inside the Earth flows out to the surface as lava or explodes violently into the atmosphere to fall back as pyroclastic. This is different from intrusive rock formation, in which magma does not reach the surface. The main effect of extrusion is that the magma can cool much more quickly in the open air or under seawater, and there is less time for the growth of crystals. Often, some of the lava fails to crystallize at all, becoming an interstitial natural glass or obsidian. If the magma contains abundant volatile components which are released as free gas, then it may cool with large or small vesicles (bubble-shaped cavities) like those found in pumice or scoria. These rocks form many kilometers below the Earth’s surface, as molten rock called magma flows into cracks or underground chambers. There, the magma cools very slowly over thousands to millions of years. As it cools, elements combine to form common silicate minerals, the building blocks of igneous rocks; the mineral crystals can grow quite large if space allows. Rocks that form in this way are called intrusive igneous or plutonic rocks. The mineral crystals within them are large enough to see without a microscope. There are many different...
