Slate is a metamorphic rock
Did you know?
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 determined by the amount and type of iron and … See more The tectonic environment for producing slate is usually a former sedimentary basin that becomes involved in a convergent plate boundary. … 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.

Geiss WebMay 10, 2024 · Slate is a low-grade metamorphic rock with a dull luster and strong cleavage. It is derived from shale by regional metamorphism. Slate forms when shale, which consists of clay minerals, is put under pressure …
WebMetamorphic rocks form when high temperatures and pressure act on a rock to alter its physical and chemical properties (metamorphism means 'to change form'). These conditions often stretch, twist and fold the rock as it cools. In metamorphic rocks some or all of the minerals in the original rock are replaced, atom by atom, to form new minerals.
