The protolith of slate is what
WebbMetamorphic rocks, meta- meaning change and – morphos meaning form, is one of the three rock categories in the rock cycle (see Chapter 1 ). Metamorphic rock material has been changed by temperature, pressure, and/or fluids. The rock cycle shows that both igneous and sedimentary rocks can become metamorphic rocks. WebbAnswer choices. K is the mylonite. It has chunks of garnet in it. K is the mylonite. It has angular clasts and slickensides on the lower surface of the sample. L is the mylonite. It has chunks of garnet in it. L is the mylonite. It displays "augen" of several minerals, with "tails" that stretch out parallel to the foliation.

WebbMetamorphism is the change of minerals or geologic texture (distinct arrangement of minerals) in pre-existing rocks (protoliths), without the protolith melting into liquid magma (a solid-state change). The change occurs primarily due to heat, pressure, and the introduction of chemically active fluids. Webb9 apr. 2024 · Phyllite is a soft and durable metamorphic rock.

It is derived from shale by regional metamorphism. Slate forms when shale, which consists of clay minerals, is put under pressure with temperatures of a few hundred degrees or so.
