What is a calcschist?

Answer 1

A calcschist is a for of metamorphosed argillaceous limestone which has a schistose structure - which is of the ability to readily divide into slabs or slates.

Answer 2

A calcschist is a metamorphic rock that forms from the metamorphism of limestone. It typically contains minerals such as calcite, mica, and quartz, and has a foliated texture due to the alignment of its mineral grains during metamorphism. Calcschists are commonly found in regions where there has been intense pressure and heat, leading to the transformation of pre-existing limestone into this metamorphic rock.
