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.   
Hawaiite is a fine-grained, hard rock that forms when bits of lava shoot out of volcanoes and reach the Earth's surface.

All about Oil shale and Hawaiite Properties

Know all about Oil shale and Hawaiite 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 Hawaiite belongs to Igneous Rocks.Texture of Oil shale is Splintery whereas that of Hawaiite is Glassy, Massive, Porphyritic, Scoriaceous, Vesicular. Oil shale appears Muddy and Hawaiite appears Dull and Soft. The luster of Oil shale is dull while that of Hawaiite is not available. Oil shale is available in black, brown, buff, green, grey, red, yellow colors whereas Hawaiite is available in black, brown, light to dark grey colors.
