Slate metamorphism
Did you know?
WebSlate is a foliated, fine-grained metamorphic rock with a slaty texture of thin, flat sheets. It has a dull luster, and is most often gray, green, black, brown, or red. Slate is formed when clay-rich shale or mudstone is subjected to low degrees of metamorphism. WebSlate, derived from shale or mudstone, is a very fine-grained, metamorphic rock with well-developed rock cleavage, and the mineral grains are not visible to the naked eye. Slate …

Slate is composed mainly of clay minerals or micas, depending upon the degree of metamorphism to which it has been subjected. The original clay minerals in shale alter to micas with increasing levels of heat and pressure. Slate can also contain abundant quartz and small amounts of feldspar, calcite, pyrite, … See more Most slates are gray in color and range in a continuum of shades from light to dark gray. Slate also occurs in shades of green, red, black, purple, and brown. The color of slate is often … See more The tectonic environment for producing slate is usually a former sedimentary basin that becomes involved in a convergent plate boundary. Shales and mudstones in that basin are compressed by horizontal forces with minor … See more In the 1800s, elementary school students used a small piece of slate mounted in a wooden frame for writing practice and arithmetic problems.

It is the finest grained foliated metamorphic rock. Foliation may not correspond to the original sedimentary layering, but instead is in planes perpendicular to the direction of metamorphic compression. employer\\u0027s certificate of insurance paWebMetamorphism also produces distinctive index minerals that form at different metamorphic grades.
