Question

What is a mineral assemblage?

Answer 1

Minerals are the various compounds or elements mixed together that are present on the surface of the earth. There are various types of minerals like quartz, mica, calcite, etc. There may be instances when various minerals are present in the composition of a rock. A rock may be examined to detect the mineral composition.

Complete answer:
There are a vast variety of minerals present in the earth’s crust. These minerals get accumulated on rocks and become a part of rocks. Rocks are a result of weathering or volcanic eruption on the earth. So, a rock may contain one or more than one mineral in its composition.
A mineral assemblage is the composition of the rock or the minerals that are present in a particular rock. It tells all the minerals assembled in a rock.
For example, the mineral assemblage of granite consists of quartz, feldspar, biotite mica and other minor minerals. Also, we can find the mineral assemblage of calcite in any rock containing calcium in large amounts.
Hence, mineral assemblage is the minerals that make up a rock.

Note:
Minerals are the compounds that have various elements in certain amounts. For example calcite has the formula $CaC{{O}_{3}}$, so it is a mineral of calcium. Elements can be extracted from their minerals or ores as they are a part of the same. There are various processes of extraction of elements from minerals and minerals from rocks.
