“…Examples of vein barite deposits are found in the Culpeper, Hartford-Deerfield, and Newark basins in the Eastern United States (Robinson and Woodruff, 1988), the North Pennine and South Pennine orefields of England (Ixner and Vaughan, 1993), and the Greater Caucasus in the Republic of Georgia (particularly the Chordi deposit) (Tvalchrelidze and Shcheglov, 1990).
