Distal scheelite skarns hosted by Cambrian metasediments.
These skarns were formed, after intrusion of the Hercynian Granitic Complex, by selective infiltrative metasomatic alteration of argillaceous dolomitic limestone.
Three main levels of strata-bound, boudin-shaped, 0.5- to 4-m-thick bodies, having a total resource of 380,000 tons (t) with an average grade of 0.51 percent WO3.
