Slate: compact, very fine-grained, metamorphic rock These notes will also be useful for other competitive exams like banking PO, SSC, state civil services exams, and so on. Brittle, massive rocks often become good host rocks in areas affected by dynamic metamorphism because shearing causes the rocks to shatter, thereby developing fluid pathways and sites for mineralization.
