Abstract:
The Xitian area is located at the northern margin of the east Hunan section in Nanling tungsten-tin-lead-zinc polymetallic metallogenic belt, and its geotectonic location is the junction belt between Yangtze Plate and Cathaysian Plate which has favorable metallogenic geological background. As an important territorial resources survey project approved by China Geological Survey in 2007, this project has deployed five aspects work as follows: 1∶50000 geological and mineral resources survey, ore area estimate, exploration demonstration, target verification, and comprehensive study. After a series of explorations and studies, we established the metallogenic geological model in Xitian area, brought forward the concept of "trinity ore-control system", determined the intrusive petrogenic age, determined the prospecting indicators, and figured out 301800 tons of tungsten and tin ore resources (332+333+334). However, as many mineral veins are still in pre-survey stage, we propose to increase exploration investment in further and to improve the resource level of Xitian area.
