| Nanwenhe scheelite deposit, a large-scale strata-bound deposit, is hosted in the Proterozoic metamorphic formation in Malipo county, Yunnan province, China..Based on the pervious researchers and detail field investigation, We are focusing on the geological characteristics, outside the geological characteristics, chronology in order to clarify the source and evolution of ore fluids,deposit genesis and geodynamic settings. There are two types of ore body occurrences, one is layered, plate-shaped, conformably hosted in and synchronal folded with the stratum; the other one is vein-type, which interludes the layered ore body, with mineralization enriched locally. The host rocks include skarnlike, leptynite, schist, tourmaline and monzonite et al. Base on chronology, Be sure that large scale mineralization event related to the Early yanshanian magmatic hydrothermal. Combined with the tectonic background, Analysis the interlayer gliding structure to its control during the formation of scheelite and yanshanian magmatic hydrothermal effect on it. To explore the structure of the Nanwenhe Metamorphic core complex, as the center of the laojun Mountain rock, as well as its control effect of Nanwenhe scheelite, Nanwenhe metamorphic core complex formation, development, evolution formed a close relationship with Nanwenhe scheelite. The surrounding has good resources potential. |
