摘要
The northern Daba Shan is part of the South Qinling orogenic belt,where deposited a set of siliceous-carbonaceous clastic rocks interbedded with carbonate sediments dominated by deep stagnant basin facies formed in the Sinian-Cambrian epoch.Previous exploration has discovered a large number of copper and zinc mineral occurrences or ore deposits,which are classified into the ductile shear zone type,quartz vein type and magmatic rocks contact metamorphic type according to the occurrence location,genesis of ore-bodies and types of the ores.Studies on the metallogenic conditions and regularities of these copper and zinc ore deposits suggest that the northern Daba Shan owns good source beds,perfect transporting and conducting systems and rich ore-storage space,indicating its large prospecting potential.It is pointed out that the of Zhuangzigou Fm.carbonate rocks adjacent to the deep and large faults are favorable ore-bearing loci.
