Wollastonite: A Versatile Industrial Mineral

1. What is Wollastonite?

a. A mineral that combines garnet and quartz.

b. A mineral that combines quartz and feldspar.

c. A mineral that combines calcite and quartz.

d. A rock form.

Answer:

Wollastonite is a mineral that combines calcite and quartz. The correct answer is C.

Wollastonite is a mineral that combines calcium, silicon, and oxygen and has the chemical formula CaSiO3. It is a white to grayish mineral commonly found in metamorphic rocks and used in various industrial applications. Wollastonite is utilized in the production of ceramics, plastics, and paints due to its beneficial properties.

It is commonly found in metamorphic and some igneous rocks. Wollastonite is a versatile mineral used as a filler in industries because of its low moisture absorption, high brightness, and reinforcing characteristics.

The options "a. A mineral that combines garnet and quartz" and "b. A mineral that combines quartz and feldspar" are incorrect. Garnet and feldspar are different minerals with distinct chemical compositions and do not form wollastonite.
