In this lab, eight unidentified mineral samples are the subject of observation and experimentation. The purpose of this lab is to identify the samples based on the observations and experimentation. This paper will identify each of the samples and briefly discuss each one.
Mineral A - Kaolinite
Kaolinite, composed of hydrated aluminum silicate, is the result of “sedimentary rocks whose sediments were derived from weathered igneous and metamorphic rocks” (Schroeder, 2013). Much like talc, it is white in color. It differs from talc in that it has pale yellow coloring. Not quite as soft as talc, kaolinite scratches very easily. The uses for kaolinite include paper, ceramics and cosmetics.
Mineral B - Olivine
Olivine is not a single mineral but rather a mineral series. By definition, a mineral series contains multiple elements that have the ability to substitute for one another but leave the crystal structure intact in the process. “n olivine, iron (Fe) and magnesium (Mg) do this, so the Olivine Series has two end members. Favalite is the iron-rich version, while forsterite is the magnesium-rich version, although any combination of magnesium and iron is possible” (UM, n.d.). This sample much like quartz and its glass-like feel and appearance and difficulty to scratch, was easy to identify as not being quartz. The olive green color of this sample made it stand out from quartz. Gemstones and brick making are among the uses for olivine.
Mineral C - Malachite
Malachite with its green color, light green streak, dull appearance and ease in scratching all helped to identify this sample. The mineral is a copper carbonate mineral “that forms at shallow depths within the Earth, in the oxidizing zone above copper deposits” (King, 2013). Currently mined in the Congo, South Africa and the Middle East, common uses for malachite include gemstone and small sculptures.
Mineral D - Magnetite
Magnetite is a mineral found within all of the rock groups: igneous, metamorphic and sedimentary rock. A black mineral with a microscopic crystalline structure and metallic luster, “Magnetite is a natural magnet, hence its name” (UA, 2005). Identifying this mineral sample was the most fun out of all the samples in this lab. I did not bother with a scratch test or go by color and feel. I grabbed a magnet off my refrigerator door and tested the attraction to one another. When my sample and magnet found one another, my testing and identification of this sample was over. The uses for magnetite include abrasives, toner, paint pigments and fertilizer.
Mineral E- Quartz
Quartz, a mineral that is one part silicon and two parts oxygen otherwise known as silicon dioxide, “is the most abundant mineral found at Earth's surface and its unique properties make it one of the most useful natural substances” (King, 2013). Found among all three rock types, igneous, sedimentary and metamorphic rock, its white streak, glass-like feel and appearance and difficulty...

Continental Margins Essay

673 words - 3 pages Continental Margins What is weathering and erosion? Weathering is basically the breakdown and alteration of rocks and minerals at or close to the Earth’s surface into products that are more in equilibrium with the conditions found in its environment. Erosion is “the removal of weathered rocks by moving water, wind, ice, or gravity” (Thomas and Turk). These two processes together help make the Earth’s surface how it is today. Weathering is a

Question: What are the 3 main kinds of rocks?

2361 words - 9 pages Question: What are the 3 main kinds of rocks?The 3 kinds of rocks are igneous, sedimentary, and metamorphic.Igneous rocks are either glassy, fine grained, coarse grained, or porphyritic. Volcanic rocks sometimes have holes in them from escaping gases (called vesicles). Sometimes the holes are filled with minerals, and then the rock is amygdaloidal. Rocks that have vesicles are usually fine grained like basalt. Volcanic rocks are fine grained

Insulation and Influences

753 words - 4 pages temperatures. Regional metamorphism occurs as mountain form and are subjected to high heat and pressure. Earth’s internal heat causes temperature to increase with depth. Overlying rock contributes to high pressure. Minerals in the rock align in layers when the pressure is stronger in one direction. This process can be speeded up with the help of hot liquids and gases in the deep rocks. The two types of local metamorphism (contact and deformational

Effects of High Fructose Corn Syrup

Obesity is a major problem, as High Fructose Corn Syrup does not release leptin—which is what signals the brain to stop eating, so society is prone to over consumption. It also alters the heart's use of other minerals and enables the appropriate minerals to reach the part of the body that needs them, (such as calcium for bones). Lack of the minerals cause
