Definition
Vogesite is a porphyritic alkaline igneous rock and is a variety of Lamprophyre which is dominated by essential amphibole, usually hornblende, and potassic feldspar
It is a metamorphic magnesium rich rock because it is composed of the mineral talc

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

Formation
Vogesite formation takes place deep beneath the Earth’s surface at around 150 to 450 kilometres, 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.
