Division of Vein Quartz Metallogenic Belts and Construction of Prospecting Model in the Southern Dabie Mountains Ultrahigh-Pressure Metamorphic Belt,Anhui Province
摘要
Abstract
Quartz veins are widely developed in the southern segment of the Dabie Mountains Ultrahigh-pressure(UHP)Metamorphic Belt,Anhui province.The ore is characterized by low impurity content and high purity,making it an ideal raw material for high-purity quartz.However,due to the generally small scale of individual veins,complex geological structures,unclear ore-controlling conditions,and the lack of systematic exploration theories,prospecting efforts in this area have historically yielded limited breakthroughs.This study systematically analyzed the metallogenic conditions and summarized the key ore-forming factors and genetic mechanisms through field investigations and detailed studies of typical deposits.Furthermore,the metallogenic belts of vein quartz were delineated,and the prospecting criteria were synthesized to establish a prospecting and exploration model.The results indicate that vein quartz mineralization in the Dabie Mountains area is closely associated with regional high-pressure metamorphism,multi-stage magmatic intrusion,and secondary tensional fault structures.It also exhibits a genetic linkage with specific stratigraphic units(or lithostratigraphic horizons).The mineralization is characterized by diverse combinations of ore-forming elements,multi-stage superposition,and complex geological processes.This study has delineated 7 vein quartz metallogenic belts and achieved significant prospecting progress in practical applications,thereby providing a theoretical basis for the exploration of high-purity quartz raw materials in the Dabie Mountains area.关键词
