Abstract: Resource distribution characteristics are considered as main factors for mineral physical geological data screening. In this paper, with comprehensive consideration of influence of various factors on the physical geological data screening, comprehensively fuzzy evaluation method is introduced on the basis of predecessors' research. Furthermore, the principle of screening classification for mineral physical geological data is established by the evaluation factors which include 8items of 3categories such as geological characteristics, metallogenic background and economic characteristics. Meanwhile, taking an example of China tin deposit, we selected and classified typical Chinese tin deposits according to the screening and grading principle by systematically analysis of resource distribution characteristics such as the metallogenic background, metallogenic zones(belts), metallogenic epoch, genetic types. Results showed that, fuzzy evaluation is a relatively more effective method for classified screening due to the great fuzziness of the evaluation factors themselves on the tin physical geological data.
