深部成矿预测已成为海沟金矿当务之急。为进一步加强区内、外找矿工作,本文提出金成矿预测新思路———控矿构造层次。依据金矿产出地质条件的不同,将金矿控矿构造划分为中部、浅部、浅—表部和表部四个层次。每个层次都有特征性的控矿鉴别标志,分别反映出是大陆张裂、隆—滑和拆离构造等多种大陆壳动力学机制转变过程中的产物。最后通过纵、横向不同层次控矿构造特征变化规律进行成矿预测。
Deep mineralization prediction has become the top priority of the Haigou gold mine. In order to further strengthen the prospecting work both inside and outside the region, this paper presents a new idea of gold mineralization prediction --- the structure of ore-controlling structure. According to the different geological conditions of gold output, the gold ore control structure is divided into four levels: middle, shallow, shallow-surface and surface. Each level has its own characterization of ore-control identification marks, respectively, which are the product of changes in the dynamics of various continental continental crusts such as the continental rift, the Long-slip and detachment structures. Finally, the ore-forming prediction is made through the variation of the ore-controlling tectonic features at different levels in the vertical and horizontal directions.
