1.1 Definition
Appinite is an igneous rock in which the crystals are so fine grained that individual minerals cannot be easily distinguished
It is a metamorphic magnesium rich rock because it is composed of the mineral talc
1.2 History
1.2.1 Origin

1.3 Etymology
From the variety of Lamprophyre Greek lampros bright and shining + porphureos purple
From 17th century, because of its greasy feel and use like a soap

8 Formation
8.1 Formation
The formation of Appinite takes place deep beneath the Earth’s surface at around 150 to 450 kms, and are erupted rapidly and violently.
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.
