The southern margin of the Altaides had undergone intensive NW-SE compression since the Late Devonian to the Early Permian, which resulted in syn-orogenic metamorphism, deformation and hydrothermal mineralization. This was another important mineralizing epoch after the Early Devonian VMS mineralization. The Low Devonian Kangbutiebao Formation (D1k), distributed in the southern Altaides, is an important host for volcanic massive sulfide Pb-Zn(Cu) mineralization. Not only had VMS ores undergone deformation and metamorphism, but gold-copper-bearing sulfide-quartz veins formed during orogeny or post-orogeny. These quartz veins can be divided into two groups. The first group of quartz (Q1) occurs as lentoid or streaked quartz veins which are parallel to the foliated structure of the biotite-chlorite or garnet-chlorite schist. These quartz veins are synorogenic and contemporaneous with early regional metamorphism, and may be gold-bearing veins, such as at the Sarekoubu gold deposit. The second group (Q2) is chalcopyrite- bearing quartz veins which cut across chlorite schist and banded sulfides at small angles, which may represent a much younger, metamorphic-related overprinting event. This proposal focus on temporal and spatial patterns between gold (copper) and lead-zinc mineralization in southern Altaides, ore-forming mechanism, overprints on ore system, as well as ore-forming chronology, so as to deepen the research on tectonic-fluid-metallogeny during orogeny in Carboniferous and Permian. The research contents which will be carried on includes three aspects. Firstly, lode gold and bedded lead-zinc mineralization in the Sarekoubu-Tiemuerte area will be concerned, which covers temporal and spatial distribution of gold and lead-zinc ore bodies, fluid inclusions of bedded lead-zinc ores and vein gold ores, overprints of lode gold, as well as chronology of mineralization and alteration. Secondly, deformation and metamorphism, overprints on lead-zinc deposit, evolution of CO2-rich inclusions in the Abagong-Talate Pb-Zn deposits will be studied, which includes textures and structures metamorphic ores, fluid inclusions in sphalerite of massive sulfide and hydrothermal vein ores, carbonic inclusions in vein quartz, as well as chronology of ores and altered rocks. And the last, late gold-copper mineralization in the The late copper-bearing sulfide quartz veins in the Mengku and Abagong iron deposits will also be studied, which contains CO2-rich fluid inclusions in the late copper-bearing sulfide quartz veins, gold-copper overprints on iron ore bodies, as well as fluid inclusions in quartz porphyroclast of mylonite and vein quartz. The distinguishing features and new ideas of this proposal can be concluded: 1) the temporal and spatial characteristics of gold and copper deposits related with orogrny and metamorphism; and 2)emphasizing preservation, decomposition, and overprints of structral ores and their fluid inclusions.
