Define the term “mineral”. Explain why in geochemistry, this definition may not always be true.
A mineral a chemical compound that you can find in nature in its pure form on or below the surface of the earth.
In Geochemistry, we are more focused on chemical structure of the mineral and also includes application of minerals to environment and hydrological activities and the studies related to mineral exploration. Thus, we can say that geochemistry includes an aspect of mineral while mineral does not include geochemistry. Geochemistry is a broader aspect. Thus, the definition is not sufficient in this case.
