Abstract

The Kaladawan Fe-Mo ore field in Altyn (Xinjiang Province, NW China) contains six Fe (-Mo) deposits, with total proven reserves of 60 Mt Fe and 10,000 t Mo. Tabular, lensoidal and stratiform orebodies occur in the Cambrian foliated marble, phyllite, carbonaceous slate, chlorite-sericite schist and quartz-sericite schist along the exocontact zone of the Kaladawan granite. Skarns are extensively developed and dominated by garnet, pyroxene, epidote, tremolite and actinolite, with minor chlorite, zoisite, quartz and calcite. Ore minerals are mainly magnetite and molybdenite. Five alteration and mineralization stages (I-V) were identified: the prograde (I) and retrograde (II) skarns are characterized by assemblages of garnet-pyroxene and epidote-tremolite-actinolite, respectively, intruded and replaced by mineral assemblages of magnetite-epidote-zoisite (III), quartz-sulfides (IV) and calcite-chlorite (V) in younging order. The Kaladawan garnet contains more andradite (61.2-94.4 mol%) than grossularite (37.5-5.0 mol%). Pyroxene is Mg-rich and Fe-poor, with an endmember range of 55.4-94.7 mol% diopside and 42.5-4.7 mol% hedenbergite. Amphibole comprises mainly tremolite and actinolite. The Kaladawan skarn mineral contents resemble typical skarn Fe and Mo deposits. In-situ LA-ICP-MS magnetite trace element analysis had identified unusually high Mg, Mo and Cr concentrations. The high Mo and the absence of molybdenite inclusions in magnetite suggest that the hydrothermal fluids may have been Mo-rich. The magnetite also contains similar (Ti + V) and (Al + Mn) values with typical skarn Fe deposits. Therefore, the Kaladawan Fe-Mo mineralization is best attributed to be skarn-type, and related to the Kaladawan granite intrusion.
