To explain what a mineral is properly, we have to introduce you to a bit of chemistry. [5] Rocks are important sources of materials for sculpture and architecture. Have you heard of oxygen, hydrogen, iron, aluminium . Water (H 2 O) is a polar inorganic compound.At room temperature it is a tasteless and odorless liquid, nearly colorless with a hint of blue.This simplest hydrogen chalcogenide is by far the most studied chemical compound and is described as the "universal solvent" for its ability to dissolve many substances. 2. The crust of the earth is made up of more than 2000 minerals, but out of these, only six are the most abundant and contribute the maximum. It is usually white or colourless. Carbonates Every Exam Solved MCQs gemstone: . It is usually tan, brown, or reddish in color, and often (but not always) displays noticeable layers. There are approximately 200 or so different sulfates, but most of those are found in very localized areas. Halite, pictured in the Figure 2.2 above, is NaCl (sodium chloride). Most minerals are chemical compounds consisting of two or more elements, however, some elements naturally occur in mineral form including gold, copper, platinum, sulfur, and iron. Minerals are simply a collection of one or more elements that are stacked neatly together in a form called a crystal structure. Mica minerals are usually found in igneous and metamorphic rocks, while clay minerals are more often found in sedimentary rocks. Chemical Composition Nearly all (98.5%) of Earth's crust is made up of only eight elements - oxygen, silicon, aluminum, iron, calcium, sodium, potassium, and magnesium . Often, many different minerals are present, but a few rock varieties are made almost entirely of one mineral. The United States has mines in Arizona, Utah, New Mexico, Nevada and Montana.

A rock is inorganic and a solid naturally-formed substance without any chemical composition or atomic structure. These low distillate inventories are why diesel prices are above $5.00 a gallon nationwide, even though the nationwide average price for gasoline has dropped below $4.00 a gallon. Two frequently found micas are dark-colored biotite, frequently found in granite, and light-colored muscovite, found in the metamorphic rock called schist. After the more easily decomposed minerals break down and disappear, the resistate minerals remain to become sediment. Rocks also change from one form to another and differ from one region to another because of the rock cycle. Different rocks have different properties; this enables us to use them in different applications. A rock usually contains two or more types of minerals. true.
