| Abstract: | Based on the spatial analytical module of MAPGIS system, this paper tries to carry out the statistical analysis of a large regional spatial data, and statistically analyses some properties of the related objects including favorable ore-forming strata, structure, magmatic rock and the distribution trend of tin-polymetallic deposits in South China. Preliminary summarization of the favorable combination index for mineralization of tin polymetallic deposits, points out that the most favorable area for tin-polymetallic deposit is the crossing place with the magmatic rocks of Yanshanian and Jinningnian and the strata of Devonian and Jurassic plus NE or NEE tectonic structure. This paper finally provides sound evidence for metallogenic prediction and related geological survey and ore exploration disposition for ore deposits. |
