Beginning with a shale parent, Barrovian metamorphism produces a sequence of metamorphic rocks that goes through slate, and then through phyllite, schist, and gneiss. It can be hard to imagine at first that all these very different looking rocks can come from the same sedimentary parent, but we know that they do.
Shale > Slate > Phyllite > Schist > Gneiss > Migmatite > Complete Melt 2 people found this useful What rock is formed when shale is transformed to metamorphic rock? Slate is the metamorphic rock ...
Slate, schist, and gneiss are three common foliated metamorphic rocks. Slate is a hard, fine-grained rock with a well-developed rock cleavage or slaty cleavage caused by the incipient growth of platy (micaceous) minerals, due to metamorphism of fine-grained clastic sediments such as shale and siltstone and also volcanic tuffs.
Slate is a fine-grained, foliated, homogeneous metamorphic rock derived from an original shale-type sedimentary rock composed of clay or volcanic ash through low-grade regional metamorphism Phyllite is a fine-grained metamorphic rock with a well-developed laminar structure, and is intermediate between slate and schist rocks
Best Answer: Shale is USUALLY the parent rock to slate and phyllite. Shale is sometimes the parent rock to schist - other rocks such as basalt and other volcanic rocks can also be transformed into schist. As for gneiss, the level of metamorphism here is so high that almost any rock composed of several ...
What sequence of rock types will shale pass through with successively higher grades of metamorphism? Shale, slate, phyllite, schist, gneiss, partial melting Match each rock with its first-order metamorphic equivalent (the first rock it would turn into when metamorphosed).
Shale produces the greatest diversity of metamorphic rocks, so many changes in fact that it is sometimes hard to believe they could all come from the same parent. We can see this in the chart below where sedimentary shale turns into slate, then phyllite, then schist, then gneiss.
*Note: Phyllite has a texture that is intermediate between slate and schist. This results in slaty cleavage and shiny cleavage surfaces but grains that are still microscopic. SLATE. Slate is a low-grade foliated metamorphic rock formed by regional metamorphism.
Metamorphic rocks in which minerals are brought into line or layers due to heat and pressure, common for regoinal metamorphism, type of foliation can identify rock. Examples: slate, phyllite, schist, gneiss
There are two basic types of metamorphic rocks. Foliated metamorphic rocks such as gneiss, phyllite, schist, and slate have a layered or banded appearance that is produced by exposure to heat and directed pressure. Non-foliated metamorphic rocks such as hornfels, marble, quartzite, and novaculite do not have a layered or banded appearance ...
