Formation
Jaspillite is a type of sedimentary rock which is formed by the compaction and sedimentation of pieces of broken or weathered rocks and minerals.
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 Jaspillite and Dolomite Properties
Know all about Jaspillite and Dolomite properties here. All properties of rocks are important as they define the type of rock and its application. Jaspillite and Dolomite belong to Sedimentary Rocks.Texture of Jaspillite is Banded, Trellis whereas that of Dolomite is Earthy. Jaspillite appears Banded and Glassy and Dolomite appears Glassy or Pearly. The luster of Jaspillite is earthy while that of Dolomite is vitreous and pearly. Jaspillite is available in red, reddish brown colors whereas Dolomite is available in black, brown, colourless, green, grey, pink, white colors. The commercial uses of Jaspillite are creating artwork, jewelry 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).
