Mineralogist's primary job is to identify and compare common rock-forming minerals, mineral structures, and mineralogical properties.
One of the related fields of geology is mineralogy: the study of minerals. Geologists rely on minerals for a number of reasons. Some minerals, such as gypsum, are not only considered as resources we use, but also as the basis for the formation of rocks. Minerals are classified in different ways based on the elements they contain. Matter (element) makes up minerals, and minerals make up rocks. Unless we have a basic knowledge of minerals, we cannot understand rocks and rock formation processes or some other areas of geology.
Mineralogists focus on the identification, chemistry, and formation of minerals. Mineralogist jobs can be in laboratories, museums, companies, or **, but they mostly work "in the field". It is not uncommon to find them in very remote places such as caves. They can focus on the mineral identification of the location of the resource, the economic value of minerals such as diamonds, and they can examine the chemical content of minerals to help understand the Earth's interior and various geological processes. No matter what field they focus on, mineralogists need to have a strong foundation in chemistry and geology.
