某地区志留系中的铀矿床,主要受硅灰岩和硅岩含矿层形态变异部位和断裂构造控制。 根据矿床构造的组合、规模和埋藏条件对其进行了分类。在腹状、似腹状、断裂状构造中矿体数量依次由多到少。矿床规模受构造规模和组合形态制约:在腹状构造中一般有与其规模相适应的工业矿床,在似腹状构造中一般有与其规模次一级或两级的矿床,在断裂构造中仅见有矿点。 成矿构造及其类型的研究,有利于成矿预测和揭露评价工程的合理布置。
The uranium deposit in the Silurian in a certain area is mainly controlled by the morphological variation sites and fault structures of the wollastonite and siliceous ore-bearing layers. It is classified according to the composition, scale and burial conditions of the deposit. In the abdomen, abdomen, rupture structure, the number of ore bodies in turn from less to more. The size of the ore deposit is controlled by the size of the structure and the combination pattern. In the belly structure, generally there are industrial deposits corresponding to their size. Generally, in the belly structure, there are deposits of one or two orders of magnitude smaller than those in the fault structure Mine point. The study of metallogenic structure and its type is favorable for the prediction of metallogenic and exposing the reasonable layout of the evaluation project.
