Is soapstone a foliated metamorphic rock?
Soapstone – Soapstone (also known as steatite, or soaprock) is a talc-schist which is a type of metamorphic rock. It is largely composed of the mineral talc and is one of the softer stone choices. It is the finest grained foliated metamorphic rock.

What type of metamorphism is soapstone?
Soapstone is a type of talc-schist metamorphic rock. It is produced by dynamothermal metamorphism and metasomatism. It occurs in the regions where tectonic plates are present, replacing the rocks with heat and pressure, with the flow of liquids, but without melting.
What is the characteristic of soapstone?
Physical characteristics Soapstone is easy to carve; it is also durable, heat-resistant and has a high heat storage capacity. It has therefore been used for cooking and heating equipment for thousands of years.
Is soapstone a metamorphism Regional?
Soapstone is a talc and carbonate containing metamorphic ultramafic rock commonly found in greenschist-amphibolite facies greenstone belts. The regional metamorphism and shear zones as pathways for CO2 containing water fluids are interpreted to have been essential to the formation of soapstone.
Is soapstone non porous?
Soapstone is a non-porous natural stone. As such, you will not have to worry about liquids sipping into the stone and staining it. This is unlike granite and marble. Porosity is an important factor when choosing your countertop material.
Is Marble foliated?
Marble is a metamorphic rock composed of recrystallized carbonate minerals, most commonly calcite or dolomite. Marble is typically not foliated, although there are exceptions.
Why is soapstone called soapstone?
Soapstone is the common name for the mineral steatite. Steatite is at least 50% talc combined with other minerals, mostly magnesite, that have been geologically metamorphosed into stone through a combination of heat, pressure and time. It is called soapstone because the talc gives the stone a soapy feel.
Is soapstone a natural stone?
The variety- Soapstone is a natural occuring stone. As such, it is only available in shades of light grey, soft white and deep charcoal. Most soapstone countertops exhibit gentle veining, with some having hues of green, blue or Perl.
