1.1 Definition

Dolomite is a sedimentary rock containing more than 50 percent of the mineral dolomite by weight

Hyaloclastite is an aggregate of fine, glassy debris formed by the sudden contact of hot, coherent magma and cold water or water-saturated sediment

5 Formation

5.1 Formation

Dolomite rocks are originally deposited as calcite or aragonite rich limestone, but during diagenesis process, the calcite or aragonite is transformed into dolomite.

Hyaloclastite is a type of Igneous rock is formed through the cooling and solidification of lava or magma.
