| 摘 要： | 海德乌拉火山岩型铀矿床是我国在西北地区发现的第一个火山岩型铀矿床，具有重大研究意义。该矿床地处东昆仑成矿带基底穹状隆起的塌陷式火山盆地中，成矿地质条件优越。本文对海德乌拉地区火山岩型铀矿床的区域地质背景、断裂构造及火山机构进行了论述，探讨其成矿特征及控矿规律，建立了该铀矿床的区域找矿标志；海德乌拉火山岩型铀矿床受断裂构造及裂隙密集带控制，空间上具有多期次叠加成矿特点，成因类型为构造-热液型。

| Abstract: | Haidewula uranium deposit is the first volcanic rock type uranium deposit discovered in the Northwest China and is important for scientific research. It occurs in a collapsed volcanic basin of a basemental uplift in the east Kunlun ore belt. Here is superior in metallogenic condition. This paper deals with regional geological background, faults and volcanic apparatus and discusses the metallogenic regularity and establishes regional prospecting marks of such deposits. The volcanic rock type uranium deposit is controlled by fault and densely distributed fracture zones and characterized by multiple spatial over-prints of metallogenic activity. Genetically it is a tectonic-hydrothermal uranium deposit. |
