Soapstone is a metamorphic rock that is composed primarily of talc, with varying amounts of chlorite, pyroxenes, micas, amphiboles, carbonates, and other minerals. [4] Because it is composed primarily of talc it is usually very soft. Soapstone is typically gray, bluish, green, or brown in color, often variegated. To better understand what a metamorphic rock is, though, we need to look briefly at what metamorphism is and how it changes rocks. Learn more.

Metamorphic rocks (changed rocks) are made when existing rocks are subjected to high temperatures and high pressures for long periods of time. Metamorphism (meta = change, morph = form) happens when molten rock intrudes other rocks and bakes the contact zone where the molten rock touches the preexisting rock. Metamorphic rocks—rocks that undergo transformations in response to changes in pressure (P) and temperature (T)—are a primary source of information for investigating tectonic processes.39 likes, 0 comments - _semi_precious_stones_ on January 24, 2022: "퐒퐩퐞퐬퐬퐚퐫퐭퐢퐭퐞 퐠퐚퐫퐧퐞퐭 퐜퐚퐧 퐛퐞 퐢 ..."This rock contains a large percentage of chlorite, exhibiting its typical green color.
