mineralogen
Mineralogen is a term that has been used in various contexts, sometimes referring to a substance or compound containing minerals, or a mixture of minerals. In some historical or less formal geological discussions, it might have been used to describe a naturally occurring solid aggregate of one or more minerals, essentially a rock. However, this term is not a standard or widely recognized classification within modern mineralogy or geology. The precise meaning can vary depending on the source and the era of its usage.
The study of minerals, mineralogy, focuses on the classification, occurrence, and properties of individual mineral species.
