Located South of Salau village, in Haute Vallée du Salat.
Granodiorite and quartz diorite massif (1.2 km2) intruded in Lower/Middle Paleozoic sandstones, pelites and limestones metamorphized into graphitic marbles.
Complex alteration :
- Albitization (replaces granodiorite plagioclases)
- Chloritization (chlorite + sagenite in cleavages replace granodiorite biotites)
- Epidotization (clinozoisite, pyrrhotite and chalcopyrite replacing granodiorite plagioclases and biotite)
- Microclinization (microcline replaces granodiorite plagioclase and quartz after epidotization phase)
- Silicification (quartz, scheelite, arsenopyrite) associated with mylonitization
Presence of tension fractures filled with black quartz + arsenopyrite + scheelite or with almandine + hedenbergite.
Presence of inverse shear fractures filled with calcite + quartz + apophyllite + chalcopyrite + galena + sphalerite.
Important contact metamorphism in marbles (diopside, vesuvianite, grossular, tremolite, calcite, clinozoisite and quartz) and metapelites (tremolite, albite, chlorite, clinozoisite and biotite).
