What are the features that will help you distinguish crystalline metamorphic rock fram a crystalline igneous rock?

Answer 1

Crystalline metamorphic rocks typically exhibit foliation or banding due to the alignment of minerals under pressure, while crystalline igneous rocks lack this feature and have a more uniform texture. Additionally, metamorphic rocks may contain minerals that form under high pressure and temperature, such as garnet or kyanite, which are not typically found in igneous rocks. The presence of parent rock structures, such as sedimentary or igneous rocks, can also indicate metamorphic origins, whereas igneous rocks form directly from the cooling of molten material.
