摘　　要：本文在简述复兴矿田水系沉积物异常和相关分析及数量化理论Ⅳ原理基础上.根据该区水系沉积物异常特点,以水系沉积物综合异常图为基础,按元素异常在105个预测单元所占面积比对12种元素实行半定量赋值.采用相关分析,结合数量化理论Ⅳ研究,详细地分析了复兴矿田整个矿区和各个分矿区各元素间组合特征.并指出了研究区元素组合特征与燕山期岩体相关,也与围岩有一定关系,区内成矿物质既来源岩浆活动,也来自地层.In this paper,based on description of abnormity of sediment in water system of Fuxingtun mineral area and the principle of number quantification theory Ⅳ,12 chemical elements abnormity of sediment in water system were carried out half quantificational evaluating in proportion as area occupied by 12 chemical elements abnormity in 105 forecast units according to characteristic of abnormity and synthesis abnormity map of sediment in water system of Fuxingtun mineral area. The combined characteristic among elements in whole mineral area and various sub-diggings were discussed and analyzed in detail by using relativity analysis and number quantification theory Ⅳ. The study results in paper indicate that the combined characteristics among elements in study areas are relative to rocks in Yenshan stage as well as to adjoining rocks, minerogenetic materials are come from magmatic activities as well as stratum in the area. Finally,the combined factors variables of geochemistry field in the area were extracted by K-LL transform in order to provide prediction variables of minerals product in Fuxing mineral area.
