Question

Quizplus · Accepted Answer

Talc deposits can form through the reaction of olivine and pyroxene with hydrothermal fluids during regional metamorphism. This process involves the alteration of these minerals in the presence of hot, chemically active fluids, leading to the formation of talc.
