Each of the following statements describes one or more characteristics of a particular metamorphic rock. For each statement, identify the metamorphic rock that is being described: a. calcite rich and nonfoliated b. loosely coherent and composed of broken fragments that formed along a fault zone c. represents a grade of metamorphism between slate and schist d. composed of tiny chlorite and mica grains and displays excellent rock cleavage e. foliated and composed predominately of platy materials f. composed of alternating bands of light and dark silicate minerals \(g\). hard and nonfoliated, often produced by contact metamorphism
Problem 3
Describe the textural changes that occur as shale goes from low-to high- metamorphic grade to form the rocks slate, schist, and gneiss.
