A borate mine in the Tincalayu borax deposit. Tincalayu open pit measures 1,500 meters wide, 500 meters long and 100 meters deep. Produces 130,000 tons/year.
Located exactly on the border of Salta and Catamrca province, in the northern part of Salar del Hombre Muerto.
The Boroquimica company used to extract the ore in Salar del Hombre Muerto (mainly Tincalayu mine) and to transport it to its Campo Quijano plant to be processed.

541 - 1000 Ma
|Neoproterozoic intrusive and metamorphic terranes|
Age: Neoproterozoic (541 - 1000 Ma)
Comments: Mixtures of metamorphic and intrusive or plutonic rocks, tracts known as crystalline, migmatitic terranes, moderately to highly metamorphosed rocks of unknown origin with or without intrusions. This classification is inherently prone to variable interpretation, as other compilers might distinguish some packages by their metamorphic or gneissic protoliths, and the associated age ranges may be more variable.
Lithology: Intrusive and metamorphic terranes
