Abstract

Tsogttsetsii area, an intrusive complex associated with Cu mineralization, is located in the South Gobi, Mongolia. We performed the cross geochemical and extended exploration survey in Tsogttsetsii area. Cu mineralization in Tsogttsetsii area is porphyry Cu type related with alkali granite intruded in Late Carboniferous to Early Permian. In the concentrated occurring to malachite appears extensively prophylitic alteration zone having a chlorite and epidote. As results of the survey, Cu contents of potable XRF and of chemical composition for altered rocks ranges 1.08 to 18.3% in the 30 points and 1.08 to 32.9% in the 13 points, respectively. Ore minerals identified in XRD analysis and polarizing microscope that samples of copper oxides were composed mainly of malachite, azurite, permingeatite and cuprite and the other minerals are pyrite, chalcopyrite, pyrargyrite, dickite, calcite, chlorite and epidote. Mineralization can be considered occurring to selectively some granite of the surrounding aplite and faults in the only upper part coming up the hydrothermal solution of the remaining residual magma after the aplite intrusion.
