Definition of Gypsum

Gypsum is a sulfate mineral that is widely and rapidly found in nature. In addition to its abundance in the earth, it appears in two main forms: as a mineral and as a sedimentary rock.

It is also known for its ability to interact with the mineral anhydrite and can be found in limestone or clay and may also exist in dolomite.

Types of Gypsum

There are two main types of gypsum:

• Natural Gypsum:

This type is most often found with salt rocks and usually appears flat. It may also occur in fibrous masses mixed with clay or sandstone. Its subtypes include:

• Gypsite:

Ground deposits with fine, parallel fibers that often appear as blocks full of cracks.

• Rock Gypsum:

A solid and compact form of gypsum, in addition to Alabaster, which is formed from fine-grained blocks.

• Synthetic Gypsum:

This type is manufactured from various industrial chemical materials. It is man-made and used in different industries and applications.

Forms of Gypsum

Gypsum comes in several different forms, including:

Crystalline Form

Characterized by its transparency and parallelogram-like structure. A well-known example is Selenite.

Amorphous Form

This form is white in color and commonly used in ornamental carvings. A well-known example is Alabaster.

Fibrous Form

Known for its distinctive luster and used in jewelry making. A prominent example is Satin Spar.
