The epithermal mineralization is related to the Capillitas diatreme, a volcanic pipe composed of intrusive and volcanoclastic rocks of rhyolitic to dacitic composition of Miocene age which is located in the granitic basement block of the Sierra de Capillitas. The deposit consists of numerous mineralized veins which crosscut the diatreme volcanics and the adjacent Capillitas granite. The different geológical environments, the alteration features and the ore mineralogy enable to distinguish between highand intermediate-sulfidation environments, which are overprinted by supergene processes. The first group is accompanied by advanced argillic alteration and silicification and in the second rhodochrosite and quartz are the predominant gangue minerals. The polymetallic character of the Capillitas epithermal deposit is clearly emphasized by its complex Cu-Pb-Zn-Fe-Mn- As-Sb paragenesis, with minor W, Bi, Sn, Te, Ag and Au and traces of Ge, Cd, In, V, Ni and Tl, present in more than 150 different minerals. Additionally, Capillitas represents the type locality for the two new mineral species putzite and catamarcaite. The hydrothermal vein system at Capillitas was formed under strongly changing p-T-X conditions. Cu, As, Te, Sn, Bi and Au represent the key metals of the high-sulfidation stage whereas the metal association Zn-Pb-Ag is typical for the intermediate- sulfidation stage. Based on fluid inclusion studies, the Capillitas deposit can be characterized by temperatures of ore formation mostly below 300 ºC and low salinities ( 6 wt. por ciento NaCl equivalent).  aArtículo en pdf (RAGA 64_3_514.pdf) 4aMineralogía 0aCatamarca96203 0aMina Capillitas958897 4aArtículo9246051 aPaar, Werner H.9588981 aTopa, Dan9588992 aAsociación Geológica Argentinaeeditor9205810 tRevista Asociación Geológica Argentinagvol.64, no.3, p.514-524x0004-4822  cAR2cdu  aidgymd2009-11-30  c42092d42092  00102cdu4070aGMbGMd2025-12-22l0oC-5r2025-12-22 00:00:00w2025-12-22yAR
