1 Definition
1.1 Definition
Syenite is a coarse-grained igneous rock which is composed mainly of alkali feldspar and various ferromagnesian minerals
Dolomite is a sedimentary rock containing more than 50 percent of the mineral dolomite by weight

5 Formation
5.1 Formation
Syenites are formed due to alkaline igneous activities and are generally formed in thick continental crustal areas or in Cordilleran subduction zones.
Dolomite rocks are originally deposited as calcite or aragonite rich limestone, but during diagenesis process, the calcite or aragonite is transformed into dolomite.

All about Syenite and Dolomite Properties

Know all about Syenite and Dolomite properties here. All properties of rocks are important as they define the type of rock and its application. Syenite belongs to Igneous Rocks while Dolomite belongs to Sedimentary Rocks.Texture of Syenite is Earthy whereas that of Dolomite is Earthy. Syenite appears Banded and Foilated and Dolomite appears Glassy or Pearly. The luster of Syenite is subvitreous to dull while that of Dolomite is vitreous and pearly. Syenite is available in brown, buff, cream, green, grey, pink, white colors whereas Dolomite is available in black, brown, colourless, green, grey, pink, white colors. The commercial uses of Syenite are cemetery markers, creating artwork and that of Dolomite are an oil and gas reservoir, as a feed additive for livestock, gemstone, metallurgical flux, production of lime, soil conditioner, source of magnesia (mgo).
