Abstract:

According to the Methodology of Deposit Modeling and Integrated Geological Information, and on the basis of geological, geophysical, geochemical, remote sensing and placer survey data in Hunan Province at the middle and large scales, 16 predicted areas are delineated by different prediction and evaluation models. By analyzing the ore-controlling factors and metallogenic regularity, combining with the comprehensive information ore predicting theory of GIS, the tin potential is predicted by quantitative and position finding methods. 221 minimum tracts are delineated, and potential resources amount is estimated at about 6.906 6 million tons, including 1.240 8 million tons proved reserves. The quantitative analysis is carried out for the predicted resources on basis of prediction models, depths, precisions and availability. Moreover, 24 exploration areas are determined, which provide scientific basis for the reasonable planning of tin exploration.
