De Brodtkorb et al. (1982) describeb such an economic Celestite-baryte
deposit in Early Cretaceous strata from the extra-Andean region of Neuquen,
west central Argentina.
The ores are located in the sub-Andean Mesozoic belt.
Data confirm an evaporitic origin for the Celestite.
The largest deposits, as in South America and Greenland,
tend to occur as epigenetic replacements in carbonate and evaporate hosts
within epeiric platforms that range in age from Silurian to early Pliocene.
