Bangong-Nujiang porphyry copper belt located in northern Tibet, is a newly discovered one, following by the Yulong porphyry copper belt in eastern Tibet and Gandise copper porphyry copper belt in southern Tibet.Currently, Gaerqiong copper-gold deposit is the first large and detailed investigation one in Bangong-Nujiang suture zone.In recent years, some supper large gold-rich porphyry copper deposits were discovered in the the western part of Bangong-Nujiang suture zone,such as Duobuza and Bolong copper-gold deposits. But on the whole, with the exception of the west of class anger Gaerqiong, Duobuza, Bolon ore deposits, the overall researching degree is not high, even no mention to the exploration model of mineral deposit.Based on the analysis of major ore-controlling factors about Gaerqiong copper-gold deposits, combined with the results of previous studies on 1∶10000 geochemical measurements, on 1∶10000 precision magnetic survey and on 1: 10000 induced polarization measurement results, it summaried the ore-controlling factors of the deposit and proposed the metallogenic model of the deposit, namely “porphyry-skarn-like IOCG”modle that is the shoshonite-high-K calc-alkaline diorite rock category, continent-continent collision with shoshonite-high-K calc-alkaline quartz remelting diorite genetically closely related to the genesis, the main ore-body laied in porphyry, skarn, structural fracture zone. Porphyry and skarn ore-bodies usually stand for the low magnetic anomalies (0~200nT), the polarization between 4% to 16%, the resistivity between 200~800Ω · m. However, as granitic porphyry and its contact with skarn have the feature of containing the high magnetic minerals,such as magnetite and pyrrhotite, they represent high magnetic (200nT above). Geochemistry shows that, on the plane, the abnormal elements are zoned clearly, overlapped and seat well, and the concentrations of that are graded obviously with the combination of elements abnormal concentration centers for Cu-Au-Bi-Mo-Ag-Sb-Zn-As-Pb, wherein Cu, Au, Mo, Bi and other elements for the inner ring, As, Sb, Pb, Zn for the peripheral elements. Like IOCG-type orebodies generally represent the low magnetic(0~200nT), the moderate polarization (4% to 6%) and the low resistivity (200 ~ 400Ω·m). On a sectional view, the apparent resistivity of like IOCG-, skarn- and porphyry-type ore bodies perform as the typical “W” type distribution pattern and the polarization ratio as “M” type distribution patterns. The content of Cu,Mo,Au and Ag corresponding to center of mineralization is significantly higher with undulating, while the content of Pb and Zn is much lower with no abnormal.The contacting zones between quartz diorite porphyry and granite porphyry and carbonate rocks, especially skarn zone at the contacting zones, are the direct prospecting marks to seeking for skarn orebodies; hematite + silica+ carbonate mineral is the symbolic mineral combination of F1 fault fracture zone, which is also the main prospecting mark to seek for like IOCG-type orebodies.
