By applying the theory and method of geological anomaly , it is focused on the analysis of the characters of major geological anomalies and their effect of mineralization in daye - jiurui region . the analysis result shows that the basement fault anomalies control a few major large hidden batholiths and their associated orefields ; that the anomalies of cover structure confine most cu - au deposits and fe - cu deposits within their scope ; that the geochemical anomalies and lithofacies - paleogeographical anomalies are major geological factors leading to trataboundness of some cu - au deposits ; that the anomalies of rock operties provide the favorable chemical and physical conditions for the ore - forming process , including the seepage , circulation , convergence and deposit of ore - bearing hydrothermal solution ; that the anomalous ctive stage of mesozoic magmatite is almost consistent with the major mineralization epoch of the fe , cu deposits , and the structure of multi - levels , and the zoning in magmatic system determine the spatial distribution of the mineralization system . then , based on the above analysis , a comprehensive variate , geological combination entropy , is brought forward for reflecting the complex degree of the combination of geological ore - controlling factors . after circumscribing the anomalies of geological combination entropy , the relations between the anomalies and ore deposits are determined 從地質異常的角度,重點分析了大冶九瑞地區主要地質異常的特征及其對成礦的影響.由分析可知:基底斷裂異常控制了本區若干重要規模較大的隱伏巖基及伴生礦田,而蓋層構造異常控制銅金礦床和鐵銅礦床的空間位置;地層的地球化學異常和巖相古地理異常是造成一些銅金礦床層控性的主要地質因素;蓋層的巖性異常為含礦熱液的滲流、循環、聚集和礦質沉淀等一系列成礦作用提供了有利的物理和化學條件;中生代巖漿巖的異常活動期也是本區主要的鐵銅成礦期,巖漿巖系統的多層分枝和分帶性結構控制了本區成礦系統的三維空間分布.在上述分析的基礎上,構置了地質組合熵作為反映控礦地質因素組合系統結構復雜程度的綜合變量,并圈定出組合熵異常,由此確定了綜合地質異常與礦床的關系
