Abstract


Papers in Chuxiong Cenozoic basin countries succeed solid mineral resources crisis mine prospecting projects, \Yunnan sandstone-type copper as an important component part of the Copper River in Chuxiong Basin Haojiatai south, in the southern extension Kangdian axis Yuanmou ancient land west of the Chuxiong Basin in south-central , northwest Chuxiong Basin in Qinghe - Chenghai fault bounded with the Indo- fold system Bayankala adjacent ; west of the Red River fault constraints, Sanjiang fold system with phase ; East to Puduhe breakage and green juice river breaks and long Kangdian axis Yuanmou ancient land uplift separated for ore mineralization area provided favorable conditions . By Hao in Yunnan Copper River area two and a half geological survey and indoor construction work completed 1:5000 geological mapping, geochemical mapping 1:2000 construction work, combined with previous data, the geological background , geological conditions , deposit characteristics and geochemical aspects of the comprehensive study , pointed out the copper mineralization Hao River ore-controlling factors , upper Cretaceous conglomerate Matoushan Department as the main ore-bearing strata . After reviewing previous research in Yunnan Copper Sandstone , based on the combination of geological conditions of the work area , the application of geochemical prospecting method , Copper River region through research Hao and elemental geochemistry anomaly studies , the establishment of geochemical anomalies ideal model . Copper body at the instructions in the combination of elements of Cu-Ag-Mo-As-Sb-Hg; indicator elements contained within the seam vertical zonation of ( top to bottom ): Zn → Cs → Pb-Tl-Mo → Cu -Ag-As → Sb-Hg; lateral zonation ( from west to east ) is a Cu-Ag-Mo → Cu-Hg-Ag-Pb-Ba → Cu-Ag-Pb-As-Sb-Hg. Through the application of geochemical methods to determine the mineralization of geochemical anomalies , delineated the forecast Zone A seven valuable exception , combining stratigraphy, lithology and other favorable ore-controlling factors , the delineation of the prospecting target , after exploration engineering experience has been implemented . Practice has proved that rock geochemical prospecting method is effective in this area .
