Formation
Formation
Syenites are formed due to alkaline igneous activities and are generally formed in thick continental crustal areas or in Cordilleran subduction zones.
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.

All about Syenite and Oil shale Properties
Know all about Syenite and Oil shale properties here. All properties of rocks are important as they define the type of rock and its application. Syenite belongs to Igneous Rocks while Oil shale belongs to Sedimentary Rocks.Texture of Syenite is Earthy whereas that of Oil shale is Splintery. Syenite appears Banded and Foilated and Oil shale appears Muddy. The luster of Syenite is subvitreous to dull while that of Oil shale is dull. Syenite is available in brown, buff, cream, green, grey, pink, white colors whereas Oil shale is available in black, brown, buff, green, grey, red, yellow colors. The commercial uses of Syenite are cemetery markers, creating artwork and that of Oil shale are an oil and gas reservoir.
