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.
Jaspillite is a type of sedimentary rock which is formed by the compaction and sedimentation of pieces of broken or weathered rocks and minerals.

All about Dolomite and Jaspillite Properties
Know all about Dolomite and Jaspillite properties here. All properties of rocks are important as they define the type of rock and its application. Dolomite and Jaspillite belong to Sedimentary Rocks.Texture of Dolomite is Earthy whereas that of Jaspillite is Banded, Trellis. Dolomite appears Glassy or Pearly and Jaspillite appears Banded and Glassy. The luster of Dolomite is vitreous and pearly while that of Jaspillite is earthy. Dolomite is available in black, brown, green, grey, pink, white colors whereas Jaspillite is available in red, reddish brown 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 Jaspillite are creating artwork, jewelry.
