| 摘 要： | 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。

| Abstract: | Metallogenic prognosis in the deep part has become the most pressing task at the moment in the Haigou gold deposit.The ore-controlling structure gradations are put forward as a new thought in metallogenic prognosis for further strength exploration inside and outside the mining area.According to the differences of metallogenic conditions,ore-controlling structure about gold deposit is divided into four structure gradations,i.e.mid,shallow,shllow-surface and surface.There are characteristic distinguishing indications and ore-controlling character in every tectonic gradation,which is respectively result changed of dynamic mechanisms which consiste of continental tension fracture,uplift-slip and dismantling structure.Finally,metallogenic prognosis is made by means of vertical and lateral changing regularities of ore-controlling structure with different gradations. |
