Definition
Dolomite is a sedimentary rock containing more than 50 percent of the mineral dolomite by weight
Boninite is a mafic extrusive rock which is high in magnesium and silica content, formed in fore-arc environments, typically during the early stages of subduction

Etymology
From French, from the name of Dolomieu (1750–1801), the French geologist who discovered the rock
From its occurrence in the Izu-Bonin arc south of Japan

Features
Host Rock for Lead, Traps for subsurface fluids like Oil and Natural Gas., Zinc and Copper Deposits
Available in Lots of Colors and Patterns, High Mg content, Is one of the oldest rock
Archaeological Significance
Formation
Dolomite rocks are originally deposited as calcite or aragonite rich limestone, but during diagenesis process, the calcite or aragonite is transformed into dolomite.
Boninite is a type of Igneous rock which is formed through the cooling and solidification of lava or existing rocks.

All about Dolomite and Boninite Properties
Know all about Dolomite and Boninite properties here. All properties of rocks are important as they define the type of rock and its application. Dolomite belongs to Sedimentary Rocks while Boninite belongs to Igneous Rocks.Texture of Dolomite is Earthy whereas that of Boninite is Aphanitic to Porphyritic. Dolomite appears Glassy or Pearly and Boninite appears Dull and Soft. The luster of Dolomite is vitreous and pearly while that of Boninite is vitreous. Dolomite is available in black, brown, green, grey, pink, white colors whereas Boninite is available in bluish - grey, brown, green, grey colors. The commercial uses 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) and that of Boninite are an oil and gas reservoir, cemetery markers, creating artwork, soil conditioner, source of magnesia (mgo).
