火山岩型热液铀矿床具有多种的容矿构造型式,除产于主断裂中或破碎带中的大脉型和透镜状矿体以及产于层间破碎带中的似层状矿体外,脉群也是常见的一种,而且是我国火山岩中某些大型热液铀矿床的主要容矿构造型式。它具有一系列特点。本文拟就这种脉群的构造特征及其形成机制作一探讨。
The volcanic hydrothermal uranium deposit has a variety of ore-hosting structure types. Except for the veins and lens-like ores produced in the main faults or in the crushing zone and the stratified ore bodies produced in the inter-layer crushing zone, The pulse group is also a common type, and it is also the main type of ore-hosting structure of some large-scale hydrothermal uranium deposits in volcanic rocks in China. It has a series of features. This paper intends to discuss the structural features of this pulse group and its formation mechanism.
