According to geology.com, dolomite is a common rock-forming mineral. It is the primary component of the sedimentary rock known as dolostone and the metamorphic rock known as dolomitic marble.

Dolostones are commonly used in the construction industry — as a road base material, an aggregate in concrete and asphalt, railroad ballast, rip-rap, or fill.
It is also used as an ingredient in the production of glass, bricks, and ceramics.
Possible Health Hazards
According to the Material Safety Data Sheet (MSDS) of Texas-based cement supplier Lehigh Hanson, Inc., dolomite has the following hazard statements: "may cause cancer," "may cause damage to organs (lung) through prolonged or repeated exposure," "causes skin irritation," and "causes serious eye irritation."
The document also pointed out that dolomites are "naturally occurring mineral complexes that contain varying quantities of quarts (crystalline silica)" and "respirable crystalline silica may cause cancer."
In 2015, US-based contractor Blue Mountain Minerals explained that dolomite can cause skin, respiratory, and eye irritation.
Moreover, a study published in Iranian Red Crescent Medical Journal concludes that exposure to “high atmospheric concentrations of dolomite” is likely to be associated with respiratory symptoms.
