1. Argentite’s composition is silver sulfide, it molecular weight equals 247.80gm. It is used as an ore of silver; reduce metal availability. It is a popular mineral, the polishing on sterling silver. Important specimens have been found in mines. Its specimen deposits can be found in several areas such as Mexico, Great Britain and Kongsberg.
2. Asbestos is found in fibers which belong to two types of mineral groups and refers to six types of naturally occurring mineral fibers. It has been historically used in industrial and construction applications.
3. Calcite is a major component of sedimentary rocks. It is common and is found everywhere. Calcite is used as a construction material, pharmaceutical, agricultural soil treatment and

It is of fine grained natural rock or soil material that combines one or more clay minerals with oxides and matter.
6. Dolomite is a rock of calcium magnesium carbonate with the chemical composition of (CAMg) (CO3)2. Its uses are cement manufacture, ornamental stone, an oil and gas reservoir and construction. One of the largest rocks on Earth is a mountain range in northeastern Italy which is part of the Italian Alps. There was a unique dolomite occurrence in Spain, and in the Congo of Zaire, which produced colorless transparent crystals resembling the Iceland Spar.
7. Feldspar is called a rock shaping mineral and is usually making up a huge part of the rock and the earth’s crust. Its composition is basic, X(AI,Si)4O8 and is used mostly in industrial mineral; ceramics and glass making. New Mexico, Virginia and Oregon are known locations of deposits.
8. Galena uses an ore of lead, its composition is lead; sulfide, PbS. Galena is metallic on fresh surfaces. It is also easy to smelt and weathers easily. Galena are sometimes mined. A cubic galena crystal with attached calcite crystals was collected at the Sweetwater Mine in Missouri.
9. Gypsum is the world’s primary ore of lead; it is mined from a huge number of deposits in many countries. It is an evaporate mineral and is found in sedimentary deposits in layers associated with halite, anhydrite,
The collection of the rocks was based on just picking up the most amount of difference looking rocks that was possible and bringing them home to analyze. This was done for about two months from many difference locations including campgrounds, beaches, rivers, highways as well as construction sites. After about two months there were many rocks so I started to analyze and take out the rocks that were of the same kind. I found many granite, basalt and conglomerate rocks.
Jade Stones “nephrite” are a mineral composed of magnesium, iron, and silicate of calcium. Usually, they are formed through extreme heat and pressure known as metamorphism. Surprisingly, it can be found on every continent in the world, including countries like New Zealand, Brazil, China (Sinkiang), Canada, Zimbabwe, and the United State. It can be found in serpentine rock, by mining, alongside riverbanks, and seashores. Due to its composition these stones are shaped and polished before it is used in massage ("Nephrite Jade Gemstone Information", 2014).
Quartz is the most abundant single mineral on earth. It makes up about 12% of the earth's crust, occurring in a wide variety of igneous, metamorphic and sedimentary rocks.Quartz varieties are commonly separated into two groups based on the size of the individual grains or crystals. Macrocrystalline quartz in which individual crystals are distinguishable with the naked eye, and cryptocrystalline quartz in which the individual crystals are too small to be easily distinguishable under the light microscope. Some of the verities of the Macrocrystalline quartz are
Conglomerate is a sedimentary rock that consists of rock fragments, many of which are visible to the naked eye (Fig. e The rock cycle states that sedimentary rocks are formed through the compression of sediment, and conglomerate contains minerals and rock that have been compressed, providing visual evidence of the rock cycle (Rocksandminerals.com, 2013).
Amethyst is purple quartz; the color is caused by iron (Fe4+) impurities. Azurite is a copper mineral. Calcite is a very common and widespread mineral and has highly variable forms and colors. Lodestone is a natural magnet. Mica is a sheet silicate. Rose quartz is translucent and a variety of the silica mineral quartz, found in pegmatite. Talc almost always found in foliated masses in metamorphic rocks with many carbonate minerals. Pyrite is a very common mineral. The brassy-yellow metallic color of pyrite has lead people to mistaking it for Gold, so its common nickname is
Next, we can see that the rock displays a subtle porphyritic texture with plagioclase comprising the phenocrysts. The overall texture of the surrounding groundmass is granoblastic equigranular. Under thin section we also see a weakly defined foliation evidenced in the preferential alignment of actinolite grains and to a lesser extent chlorite grains. Undulose extinction is also observed in quartz indicating the rock was subject to deformation. The normalized quartz, alkali-feldspar, and plagioclase (QAP) values of this rock indicate that it is classified as a grano-diorite according to the IUGS QAPF classification system which is consistent with the hand sample interpretation.
10. The minerals shown in Figure 1.12 (p. 7 lab book) are fluorite and topaz that have been tested for hardness. Use the Mohs scale in Figure 1.11 (p. 7 lab book) to identify which is fluorite and which is topaz.
This is a relatively new mineral found in the world. “Benitoite is sometimes called the "blue diamond." In the early 20th century is was first found in a California river known as the Benito River. The people that discovered it thought it was a sapphire or a diamond. Just looking a Benitoite gemstone, it would be easy to get them confused. Earth has many kinds of rocks and minerals but this gemstone is the rarest of the rare.
There are two types of minerals that we find in Earth - rock-forming and ore minerals.
Gypsum is the most common sulfate and has extensive deposits and found through the world. Main locations of gypsum mines are within the United States (in California, Iowa, New York, Texas, and Oklahoma), Candida, Spain, Thailand and Iran. One un-noted location within in the United States is New Mexico where White Sand dunes are frequent due to the crystal origins in mines within Mexico which wind blows particles into New Mexico. Gypsum are mainly found in sedimentary rocks and are usually the first to be deposited due to it crystalizing from evaporation of saltwater (waters that are usually high in calcium and sulfates). It also commonly occurs interstratified through limestones and stales. If gypsum recrystallizes in veins, satin spar is then
They cost 75 dollars per square foot. Quartz is made of silicon and oxygen atoms. On the Mohs scale it is 7 for hardness. The category it is under is oxide mineral. The crystal structure is trigonal. The Chemical formula is SiO2. The luster is vitreous, waxy, dull. The streak color is white. The fracture is conchoidal. Quartz is found in all types of rocks igneous, metamorphic and sedimentary. Quartz is resistant to weathering. White sands are the easiest way to find quartz in the sand. There is also some white or pink feldspar as well. Quartz is one of the most common minerals in the earth crust. Quartzs is a constituent of granite and felsic igneous rocks.
Gypsum is a great example because it can be used for industrial things, like a house, or can be in food items. Essentially, when Gypsum is used in a house, there are many different benefits. It could be lifesaving if your house was on fire or overheating. In addition, Gypsum in food can help you take in more calcium, which is essential to the human body. Gypsum has many other surprising uses that is not just for industrial or food use. Also other minerals like Fluorite can be used in toothpaste or Diamonds can be used as jewelry or for industrial use to cut materials. Overall, minerals are used in everyday life because they surround you. They are in the food at the grocery store, in the walls of houses, in toothpaste, and in many other things that you use
In my opinion the most useful mineral for human civilization will be Asbestos. It was given the name to a group of minerals that occur in the environment as bundles of fibers. The fiber is resistant to heat, fire, and chemical inert. This is suitable because it is use in fireproof fabrics, paper, gaskets, roofing composition, brake linings, tiles, cement, and chemical filters. Asbestos its use for everything. Research study and proclaims that Asbestos is the number one mineral use among human beings.
Copper deposits usually found along with other elements such as lead, silver, gold and zinc in Earth’s crust. Porphyry copper deposit is a large body of rock which a large amount of copper can be found. This deposit began when a large amount of molten rock slowly cooled and crystallizing inside the Erath’s crust. A large crystals was developed during the cooling process, along with the smaller size forming around them. This smaller rocks are porphyries. Initially, the molten rock contained small amount of copper, as the molten rocks cools and other minerals solidify, the copper in the fluids increase in concentration. As the process of crystallization made the rock shrink and formed cracks, the fluid containing copper run along those cracks
iatomaceous Earth is naturally-formed sedimentary mineral rock made up of fossilized remains of tiny, aquatic organisms call diatoms. Whoa! That was a lot to take on in one sentence, but don’t worry I am about to explain what this means! Although you may have never heard of diatomaceous earth it is commonly used in a range of products such as water filtering, food manufacturing, skin products and even farming, as it naturally eliminates free radicals, viruses, insects, parasites and other harmful organisms.
