5.1 Formation

Andesite is a fine-grained igneous rock that forms when the magma is erupted onto the surface and is crystallized quickly.

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.

Andesite vs Soapstone Information

Earth’s outer layer is covered by rocks and these rocks have different physical and chemical properties. As two rocks are not same, it’s fun to compare them. You can also know more about Andesite and Soapstone Reserves. Andesite is a dark, fine-grained, brown or greyish intermediate volcanic rock which is a commonly found in lava. It is a metamorphic magnesium rich rock because it is composed of the mineral talc. These rocks are composed of many distinct minerals. The process of formation of rocks is different for various rocks. Rocks are quarried from many years for various purposes. You can check out Andesite vs Soapstone information and Andesite vs Soapstone characteristics in the upcoming sections.
