Barite/celestite/selenite/calcite mineralization at Bell Lake sink, Lea County, New Mexico
— Carol A. Hill

Sulfur, carbon, oxygen and strontium isotope values of barite, celestite, selenite and calcite at Bell Lake Sink suggest that Bell Lake Sink may be a structure such as a breccia pipe which connects a brine reservoir at depth with the surface. The ultimate source of barium and strontium for the barite and celestite may be the anhydrites of the Castile and Salado Formations and also oil-field brines in the Bell Canyon Formation. Age of mineralization could be late Quaternary.
