Abstract

Sulfur and strontium isotope analyses have been used to test the possibility that barite veins in the Galeana district of northeastern Mexico formed where barium-bearing solutions intersected an overlying gypsum-bearing unit. Barite at Galeana occurs in essentially monomineralic veins in red beds of the Mesozoic-age Huizachal Group at and just below its contact with gypsum of the Olvido Formation. Sulfur isotope analyses confirm that the sulfur in the barite (δ34S = 12.3-17.4‰) has the same range as Olvido gypsum (13.1-17.6‰) Solubility calculations and data on barium and strontium contents of formation waters indicate that a fluid volume of about 1011 m3 would be required if the mineralizing solution contained about 100 ppm barium. -from Authors
