   The tungstiferous district is located in the eastern edge of Altohuasi – Culampajá hills, Catamarca province, Argentina. Julia Virginia lode is situated in the northern flank of Pachao hill at an approximate height of 3.500 m a.s.l. In the studied area mainly out crop metamorphic rocks of Loma Corral Formation and orthogneis rocks of Chango Real Formation. The ore mineral is wolframite disseminated in quartz veins filling fractures that affect the metamorphic rocks. The fluid inclusions presents in these veins were studied. Six types of inclusions have been recognized, including biphasic aqueous and vapour inclusions, H2O–CO2 inclusions and triphasic inclusions with NaCl crystals.2O–CO2 inclusions and triphasic inclusions with NaCl crystals.
