浅析红山子盆地西环推覆构造与铀钼成矿关系
|
摘要
红山子铀矿床是我国北方比较典型的火山岩型铀矿床。区内成矿地质条件优越,构造活动强烈。构造与成矿关系密切,它既是区内各种地质体之间耦合关系的主导因素,也是矿(化)体赋存的主要部位。作为该区重要的构造类型之一,推覆构造是本区F1断裂以西最主要的控矿因素。目前,区内推覆构造的表现形式、精细构造组成、形成时代及其对矿化的控制或破坏作用研究甚少,且存在很大争议,因此,加强构造控矿特征及其构造活动形成产物(断裂构造岩和充填于断裂构造中的矿脉)的研究,对指导推覆构造区的找矿工作有着重大的意义。本文着重对推覆构造的形成过程以及控矿作用进行了推断和讨论。
The Hong Shanzi uranium deposit is the typical volcanics-type uranium deposit In the North of China There are some good conditions for the formation of the Hong Shanzi uranium deposit,and tectonic activities frequency.The structure is on intimate with the formation of the deposit,it is a location where the deposit occurrences,and a dominating factor which controls the coupling relationship of a variety of geologic body.As a Important types of strcture,The nappe structure has a important effect for the formation of deposit,it is the main control factors which is the formation of deposit located nappe area land west of the F1.So far there is few research about forms、composition of fine Structure、formation age of the deposit and the action of control or destruction of the nappe structure,and there is a great deal of disagreement,so to enhance research about feature of structure contro and the result of tectonic motion(vein located in the faulting tectonic rocks and filled in the structure),has a significance to guide to mineral prospecting.In this article,the forming process of nappe structure,and the effect ore-controlling will be emphasized to concludeing and discussing
