Regional metallogenic models for the Chizhou area,Anhui Province
摘要
Abstract
Major mineral deposits in the Chizhou area of Anhui Province are of skarn,hydrothermal,weathering and leaching,depositional superimposition and reworking types. Dominating in the area,the skarn type is further divided in-to the strata-bound,mixed and contact subs according to its mineralization characteristics. Ore bodies are mostly hosted in the Tangtou Formation of Ordovician about the S-O stripping surface,the upper horizon of Devonian,the Devonian-Carbonaceous boundary,the Huanglong-Chuanshan Formation of Carbonaceous and carbonate strata of Permian and Tri-assic. Important mineralization conditions in the area include the early Yanshanian intermediate-acid magmatic rock,in-terlayer decollement,favorable carbonate stratum,the binding place of structures of different direction and different na-ture. On the basis of a summary of previous work results of other geologists,this paper established regional metallogen-ic models for this area classifying mineral deposits into three major series: (1) W,and Mo-dominant series related to early Yanshanian calc-alkaline mantle-crust syntectic first intrusive;(2) Cu,Fe,S,Pb,Zn,W,Mo,(Au,Ag)series having to do with early Yanshanian mantle-crust syntectic diorite intrusion;(3) Ag,Cu,Fe,Pb,Zn polymetallic series con-cerned with late Yanshanian continental crust reworking type Si-and alkali-rich granite.关键词
