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
It is a metamorphic magnesium rich rock because it is composed of the mineral talc

Formation
Hyaloclastite is a type of Igneous rock is formed through the cooling and solidification of lava or magma.
Soapstone is a talc-schist, which is a type of metamorphic rock and it is largely composed of the mineral talc and is thus rich inmagnesium.
