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徵及其對成礦的影響.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、聚集和礦質沉澱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佈.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,並圈定出組合熵異常,由此確定了綜合地質異常與礦床的關系Hualun 110kv transmission power station automation system
