Physical properties
Barite has a Mohs hardness of 3 to 3.5, white to clear color, vitreous luster, and perfect cleavage. The host matrix is a dark, vesicular igneous basalt rock.
Formation & geological history
Formed through hydrothermal precipitation of barium-rich fluids within gas cavities or fractures of volcanic basalt rocks.
Uses & applications
Used in industrial drilling muds, chemical manufacturing, and as a sought-after specimen for mineral collections.
Geological facts
Barite is unusually heavy for a non-metallic mineral due to its high barium content, earning it the historical name 'heavy spar'.
Field identification & locations
Easily identified by its high specific gravity, tabular crystal habit, and reaction-free nature with acid compared to calcite.
