| Abstract/Notes | The Early Cretaceous Halasheng deposit, located in the southern Erguna Block, is an intermediate sulfidation epithermal Ag-Pb-Zn deposit in the Derbugan metallogenic belt. The Halasheng deposit comprises both proximal skarn mineralization and distal hydrothermal vein-type Pb-Zn-Ag mineralization, which can be further divided into three stages represented by Fe-As-S, Pb-Zn-Cu-Fe-S, and Ag-Pb-Zn-Sb-S element associations. The main ore minerals in the Halasheng deposit include galena, sphalerite, pyrite, arsenopyrite, chalcopyrite, bournonite, falkmanite, and argentiferous minerals. Visible silver in the form of independent argentiferous minerals, mainly including freibergite, polybasite, stromeyerite, pyrargyrite, acanthite, and native silver, is the major type of silver occurring in the Halasheng district. Fluid inclusion studies of sphalerite and quartz from different mineralization stages revealed that skarn mineralization has the relatively highest homogenization temperature (322 398 °C), while in the vein-type hydrothermal mineralization stage, the homogenization temperature has a declining trend from the early stage to late stage (from 300 350 °C to 145 236 °C). In the whole mineralization process, the salinity of ore-forming fluids is almost constant at a relatively high level (10.5 21.9 wt% NaCl). Fluid cooling, or fluid–wallrock reaction, is supposed to be the major cause of metal precipitation in the Halasheng deposit. Through an analogy with the typical Ag-Pb-Zn deposits in the Derbugan metallogenic belt, it is suggested that the discovered orebodies in the Halasheng deposit likely belong to the shallow part of the epithermal system, and there is high potential to discover Zn, Cu-Zn orebodies, and even porphyry Mo-Cu mineralization. In terms of regional ore prospecting, Early Cretaceous intermediate-acid intrusions have the potential to form related Ag-Pb-Zn deposits and should receive special attention. Furthermore, places where Lower Cambrian marbles are exposed or concealed are favorable settings for skarn mineralization. |
