成岩成矿深度的构造校正测算方法,是从测算压力中先消除构造附加静水压力之后再计算上覆岩石厚度,即成岩成矿深度的方法(吕古贤和刘瑞珣,1999)。该方法建筑在对地壳岩石处于固体应力状态的认识之上,采用弹性固体模型代替静止流体模型,比沿袭至今单纯用压力/密度方法得出的深度更符合于实际情况。该文以胶东玲珑-焦家式金矿床为例,介绍了该方法的理论基础和野外地质研究方法——开展变形岩相形迹填图,在室内利用三维变形和古差应力测量,计算差应力时根据样品所处构造
The method of tectonic correction for diagenetic mineralization depth is to calculate the overlying rock thickness (ie, the depth of diagenesis and mineralization) after eliminating the additional hydrostatic pressure from the measured pressure (Lu and Yin, 1999). The method is based on the recognition that the crustal rock is in a state of solid stress. The use of the elastic solid model instead of the static fluid model is more realistic than the depth obtained by simply using the pressure / density method. Taking the Linglong-Jiaojia gold deposit in Jiaodong as an example, this paper introduces the theoretical basis of the method and the field geology research method-carrying out the metamorphic lithofacies mapping, using three-dimensional deformation and paleo-stress measurements in the room to calculate the differential stress According to the sample structure
