Calcite is a mineral made of calcium carbonate. It is one of the most common minerals on Earth and comes in a wide variety of shapes and colors. Calcite and aragonite are polymorphous to each other; they contain the same chemical composition but differ in crystal structure.Know More
Calcite is usually found in sedimentary, metamorphic and igneous rocks. It is the main component of limestone, marble and the Earth's crust and is one of the most widely used minerals. The properties of calcite make it suitable for agricultural soil treatment, construction material and pharmaceutical applications. Crushed limestone and marble are also used to neutralize acids in areas where streams have large quantities of acid mine drainage.
According to the University of Minnesota, calcite occurs in both crystalline and massive forms. Crystals of calcite are usually transparent to translucent, whereas masses of calcite tend to be light colored. Both these forms of calcite can create a wide range of colors when exposed to small amounts of impurities, which gives them a unique appearance depending on their location in the world. In powdered form, calcite often has an extremely white color that is used as a white pigment or "whiting," according to Geology.com.Learn more about Geology
Calcite is a mineral used in many ways, serving as a construction material and aggregate, a pigment, agricultural soil additive and an ingredient in pharmaceutical products. Calcite is most often found in limestone and marble, with many applications in those forms.Full Answer >
Sandstone forms over the course of centuries, as deposits of sand accumulate in rivers, lakes or on the ocean floor, and the sand blends with calcite or quarts and then undergoes compression. After enough time goes by, the pressure pushes all of these elements together to create sandstone. Because not all sand is identical but instead comes in a variety of colors and grain textures, each formation has a unique appearance.Full Answer >
A dolostone or dolomite rock is a former limestone wherein the calcite is replaced by dolomite, according to About.com. Geology.com states that this is a type of sedimentary rock found in sedimentary basins all over the world.Full Answer >
An example of an inorganic mineral is calcite. Having a trigonal system, it appears pearly with a vitreous or glass-like lustre. Calcite, a common mineral, can be found in colors such as red, yellow and white.Full Answer >
