A Study Of Development Prospects Of Fluorite In China And Assessment Of Mineral Resources Potential In Strategy Blocks

1 With the development of economy, fluorite, as an important strategic resource in China, has got quite bright development prospects. However, after decades of large-scale exploration, the easily-found outcrop mine, shallow mine and known mine are reducing and the difficulty for ore-finding is enlarging. Therefore, it is significant both theoretically and practically to have assessment of fluorite block and strengthen geological exploration and research to predict the locations of concealed and semi-concealed fluorite deposits.This paper, with relevant industrial development tendency as the basis, has compared and analyzed current domestic and foreign developments, and supply and demand situation of fluorite resources, and through meta-analysis, made quantitative forecasts on the demand and development prospects in the following 5-10 years in China. After analyzing the main factors that influence the strategic area selection of fluorite resources in China comprehensively, this paper has formed an evaluation indicator system for strategic selection, on which a quantitative ordination of the provinces and areas has been made that have abundant fluorite resources. Then, the author makes potential assessment and prediction of fluorite in Chifeng, an important fluorite place in Inner Mongolia----------the top second in the quantitative ordination, and learns that the studied area has advantages for fluorite metallogenic and potentials for ore-finding. According to the advantages for fluorite metallogenic and the development characters of known mineralized cues, the author divides the prospecting target of fluorite in the studied area into two categories---------- Class A, the key target, including Linxi, Wengniuteqi, Aohanqi and Kelaqinqi; Class B, the prospecting target, including northwest of Lindong, Daban-----Tianshan and the surrounding areas of Jingpeng, Keshenkeqi. In the end, with the study of mineral deposit geology as basis, and VLF-EM and EH4 electromagnetic image as main methods, this article, taking Xiaosijia-Xiaolongfenggou fluorite mineral belt in Aohanqi, Chifeng area, as an example, shows the innovative exploration in evaluative methods for the location prediction of the concealed fluorite deposits in the covering area, and confirms the prospects and resource scale in Xiaosijia-Xiaolongfenggou fluorite mineral belt.
