Abstract

Stratiform sulphide mineralization, believed to be of syngenetic origin, both on the French and Spanish sides of the central Pyrenees, may prove to be of economic interest. Some observations are reported, including quantitative probe analyses of sphalerite, pyrrhotite, chalcopyrite, galena, arsenopyrite, and pyrite from the Liat area. Metamorphism to greenschist facies conditions at 3.5-4 kbar caused recrystallization and annealing, followed by some limited remobilization of the ore minerals that locally gave crosscutting veins in the country rock. -R.A.H.
