“…Of all the diversity of metamorphic rocks [35], the carbonate facies by the presence of marbles [136] and, in part, greenstone formation, similar in composition to ultrabasic and basic igneous rocks can most reliably be diagnosed [40,12,91,1,3,28]. They have been studied and described from different standpoints of composition, age, structure, and ore content [45,93,94,157,[68][69][70]. The various formational groups among the metamorphic rocks are distinguished [146,106,87].…”
