Question

What are minerals.Explain?

Answer 1

Answer:

The geological definition of mineral normally excludes compounds that occur only in living beings. However some minerals are often biogenic or are organic compounds in the sense of chemistry. Moreover, living beings often synthesize inorganic minerals that also occur in rocks.

The concept of mineral is distinct from rock, which is any bulk solid geologic material that is relatively homogeneous at a large enough scale. A rock may consist of one type of mineral, or may be an aggregate of two or more different types of minerals, spacially segregated into distinct phases.

Answer 2

• A mineral, or mineral species, is a solid chemical substance that exists naturally in pure form and has a very well-defined chemical composition and crystal structure. 
• Compounds found solely in living organisms are usually excluded from geological definitions of mineral. 
• However, some minerals (such as calcite) are typically biogenic or organic substances in the sense of chemistry (such as mellite). 
• Furthermore, living organisms frequently create inorganic minerals , which are also found in rocks.
• Minerals are separate from rocks, which are any large-scale solid geologic material that is relatively homogenous. 
• A rock can be made up of only one type of mineral, or it might be made up of two or more different types of minerals that have been separated into various phases spatially.
