Decompression and Exfoliation weathering are common in Mica and Shale.
Shale.
Because it does,that the main reason jkThe mild heat and pressure that changes clay into shale causes the minerals in the clay to align and compress into more crystalline layers, ie. mica.
the metamorphic rock that is easily split is...A Mica, A Pumice and A Sulfur
The most common nonferromagnesian member of the mica family is muscovite.

Decompression and Exfoliation weathering are common in Mica and Shale.
Shale.
The most common minerals in gneiss are quartz, potassium feldspar, and sodium feldspar. Smaller amounts of muscovite, biotite and hornblende are common. Gneiss can also form from gabbro or shale.
yes, it's slate. it goes from shale to slate to phyllite to mica schist.

A Mica Garnet schist is a metamorphic rock formed from a shale or a granitic mother rock when this is squashed and heated at death in the crust.
Gneiss is a high grade metamorphic rock, the product of various rock types being exposed to intense pressures and heat under the surface of the Earth. Orthogneiss is a gneiss whose parent rock was igneous, and paragneiss is a gneiss whose parent rock was sedimentary.
some minerals are mica, fledspar, and rocks are marble, shale ,slate,granite etc.

Slate is so hard because it came from shale that is put under pressure with high temperature. The clay composition of shale converts to mica, making it hard.
The most common nonferromagnesian member of the mica family is muscovite.
