Mineralogists study minerals, their composition, structure, properties, and processes of formation. They analyze mineral samples, conduct fieldwork, and use advanced techniques to identify and classify minerals. Junior mineralogists focus on assisting with research and data collection, while senior and lead mineralogists oversee projects, mentor teams, and contribute to strategic exploration and resource management efforts.
