La Judita mine is located at 70 Km NE of Uspallata, in the province of Mendoza, cióse to San Juan limit. The outerops are irregular bodies elongated N-S, of small dimensions (with a length not exceeding 500 meters), emplaced on the western flank of the Precordillera. The main work is a quarry from which 500 tons m3 of material was extracted, constituted by tale with minor amount of chlorite, tremolite, calcite and iron oxides and hidroxides. Steatized sector, serpentini- zed altered zone and the chloritic schist (country rock of intrusive) were analyzed. Two polymorphs of serpentine were identified: antigorite (the main mineral developed during the serpentinization of the ultramafic rock) and chry- sotile in veins with irregular distribution. In the intensely altered zone, it was observed that tale is cióse related with chlorite, calcite and iron oxides. In the tale ore asbestiform morphologies were not distinguished, although in the serpentinitic bodies, cióse to the mine, chrysotile veins were recognized
