摘要
Stratigraphic framework, tectonic framework and magmatic evolutionary series have been established in 1∶50 000 regional geological survey in Linxiang,Hunan Province. A zircon SHRIMP age of (829±13) Ma is obtained from the volcanic tuff in the Huanghudong Formation, which can provide age information for regional stratigraphic correlation and tectonic evolution history of Jiangnan orogenic belt. Many ore deposits(points) are newly found: 14 gold ore occurrences, 9 tungsten ore occurrences, 1 copper polymetallic ore occurrence, 1 zinc ore occurrence and 1 ilmenite stream ore occurrence. The newly found Xintangchong gold deposit and Xichong tungsten deposit is conformed to be mini-type deposis.
