Definition
Hawaiite is volcanic rock that resembles basalt. It is an olivine basalt with intermediate composition between alkali olivine and mugearite
It is a metamorphic magnesium rich rock because it is composed of the mineral talc
Origin
Hawaii Islands

Etymology
From Hawaii Islands
From 17th century, because of its greasy feel and use like a soap

Formation
Hawaiite is a fine-grained, hard rock that forms when bits of lava shoot out of volcanoes and reach the Earth's surface.
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.
