矿山厂层控铅锌矿床赋存于下石炭系摆佐组的碳酸盐岩地层内,并与一定的构造运动有着密切的成生联系。在地质历史过程中形成的矿床,其主岩与矿体都经历过多次构造运动,致使成矿与构造的关系变得模糊不清,而欲恢复成矿期构造,现行常用的方法是难以解决的。在矿山厂我们以控矿地层底板高程作为地质变量。采用地质推断取值法确定控制点,并应用多项式趋势面分析模拟构造运动的演化过程,从中鉴定出控矿构造模型,为恢复成矿期构造提供了依据。
The ore-bearing stratabound lead-zinc deposits occur in the Carbonate strata of the Lower Carboniferous Zuozuo Formation and are closely related to certain tectonic movements. In the geological history of the deposits formed, the host rock and ore body have experienced many tectonic movements, resulting in the relationship between mineralization and structure become blurred, and to restore the metallogenetic structure, the current commonly used method is difficult fixed. At the mines we use the floor of the ore-controlling formation as the geological variable. The geological control method was used to determine the control points. The trend of tectonic movement was simulated by the trend analysis of polynomial, and the ore-controlling tectonic model was identified, which provided the basis for the restoration of the metallogenic period.
