| Abstract: | Based on the comprehensive analysis of tungsten and tin mineralization in Nangling, the information favorable for ore formation are abstracted and constructed by the method of evidence weight on the system of Morpas. We have predicted favourable areas according to the ore formation probability values. The prediction shows 4 minerogenetic prospective areas. Most of the tungsten and tin deposits which have been proven were contained by the Guposhan pluton, Jinjiling pluton and Dadongshan pluton. Lianyang pluton has not yielded tungsten and tin deposits. The conclusion of prediction has some indiction for further ore finding in this area. The research has shown that the evidence weight model on system of Morpas is easy to realize and has reliable results. The is helpful to increase efficiency and accuracyof mineralizing predication. |
