Definition
Hyaloclastite is an aggregate of fine, glassy debris formed by the sudden contact of hot, coherent magma and cold water or water-saturated sediment
Dolomite is a sedimentary rock containing more than 50 percent of the mineral dolomite by weight

Formation
Hyaloclastite is a type of Igneous rock is formed through the cooling and solidification of lava or magma.
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 Hyaloclastite and Dolomite Properties
Know all about Hyaloclastite and Dolomite properties here. All properties of rocks are important as they define the type of rock and its application. Hyaloclastite belongs to Igneous Rocks while Dolomite belongs to Sedimentary Rocks.Texture of Hyaloclastite is Pyroclastic whereas that of Dolomite is Earthy. Hyaloclastite appears Dull and Dolomite appears Glassy or Pearly. The luster of Hyaloclastite is dull and grainy while that of Dolomite is vitreous and pearly. Hyaloclastite is available in brown, grey, yellow colors whereas Dolomite is available in black, brown, colourless, green, grey, pink, white colors. The commercial uses of Hyaloclastite 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).
