The residual barite deposits in the Cartersville, Georgia District, were formed by secondary concentration of primary barite veins and barite-filled breccias. The deposits are found in deep, 200 feet thick, residual clays. Primary barite was formed by precipitation of barium-bearing solutions in shattered Lower Cambrian dolomite. The mineralization is thought to be associated with magmatic activity during Appalachian deformation in late Carboniferous time. Primary fluid inclusion in the barite homogenize in the temperature range of 126 degrees to 297 degrees C (uncorrected for pressure). This is compatible with hydrothermal derivation of the solutions. A 5,000 feet depth of emplacement requires a +20 degrees to 30 degrees C pressure correction for these temperatures. Boiling seems not to have occurred during the time of inclusion entrapment. Lack of daughter salts in the inclusions is indicative of salinities below about 26 weight percent.
