WebMetamorphic Rocks: New rocks formed from metamorphism. Examples include slate, schist, and gneiss. Related Processes: Deformation: the process of changing the shape or size of a rock due to stress, which can occur during metamorphism. WebSlate is formed by a metamorphosis of clay, shale and volcanic ash that results to a fine-grained foliated rock, resulting in unique slate textures. ... form schist and gneiss. This …
Slate during metamorphism
Did you know?
WebThe main factors that control metamorphic processes are: the mineral composition of the parent rock, the temperature at which metamorphism takes place, the amount and type of pressure during metamorphism, the types of fluids (mostly water) that are present during metamorphism, and the amount of time available for metamorphism. Parent Rock The WebSlate is a fine-grained metamorphic rock with perfect cleavage that allows it to split into thin sheets. Slate usually has a light to dark brown streak. Slate is produced by low grade metamorphism, which is caused by relatively low temperatures and pressures. Slate has been used by man in a variety of ways over the years.
