Formation

Formation
Oil Shale forms on the beds of seas and lakes and its formation starts with the organic debris settling and accumulating at the bottom of a lake or sea which are then transformed into rock with the help of high temperature and pressure.   
Migmatites form by high temperature regional and thermal metamorphism of protolith rocks where rocks melt partially due to high temperature.

All about Oil shale and Migmatite Properties

Know all about Oil shale and Migmatite properties here. All properties of rocks are important as they define the type of rock and its application. Oil shale belongs to Sedimentary Rocks while Migmatite belongs to Metamorphic Rocks.Texture of Oil shale is Splintery whereas that of Migmatite is Foliated. Oil shale appears Muddy and Migmatite appears Dull, Banded and Foilated. The luster of Oil shale is dull while that of Migmatite is dull to pearly to subvitreous. Oil shale is available in black, brown, buff, green, grey, red, yellow colors whereas Migmatite is available in black, bluish - grey, brown, brown- black, dark greenish - grey, dark grey to black colors. The commercial uses of Oil shale are an oil and gas reservoir and that of Migmatite are cemetery markers, jewelry, tombstones, used to manufracture paperweights and bookends.
