- Abstract:
- Kangkai iron deposit is located in the northern margin of the middle section of Tiekelik tectonic belt, West Kunlun, China. There are two types of iron mineralization including specularite and magnetite, which develop within the metamorphic rocks of Proterozoic Kalakashi Group and Ailiankate Group. The specularite mineralized body is controlled by fault structures, occurring as vein, stratoid, massive and veinlet. The magnetite mineralized body occurs both in the itabirite and the basic rock, the former is resulted from sedimentary-metamorphic process, and the latter is shown as disseminated magnetite and minor chalcopyrite developed within the basic rock. In terms of the characteristics of mineral assemblage and paragenetic association, ore texture and structure, wall rock alteration, and crosscutting relationship of different types of mineralized body, the mineralization of Kangkai iron deposit is divided into sedimentary, metamorphic, magmatic, and tectonic hydrothermal periods, namely this deposit is the product of multi-period superposed mineralization. The specularite formed during tectonic hydrothermal period is derived from the magnetite formed during sedimentary-metamorphic and magmatic periods, consequently the specularite occurred in shallow ground can be used as a kind of prospecting criteria for the exploration of magnetite related to the itabirite and basic rock at depth and surrounding area, and this prospecting criteria could be applicable to the whole Tiekelike tectonic belt.
