摘要
赖子山背斜为黔西南卡林型金矿重要的控矿构造之一,央友金矿床位于该背斜南西段轴部。本文以央友金矿床为例,基于区域矿产地质调查和对赖子山背斜南西段开展的地球化学、山地工程等综合地质研究,对矿床地质特征及找矿方向进行了探讨。研究表明,该区金矿在赖子山背斜两翼层间滑动构造、NE向断裂构造及其次级断裂构造带均有分布。矿床总体上受背斜东翼的层间滑动断裂控制,呈层状、似层状产于二叠纪猴子关组,即矿体具有断裂、断裂+多层岩性组合联合控制的形态特点。
Laizishan anticline is one of the important controlling structures for Carlin type gold deposits in southwestern Guizhou province,while Yangyou gold deposit is located in the southwest axis of the anticline.In this paper,taking Yangyou gold deposit as an example,based on regional geological survey and comprehensive geological research on geochemistry,mountain engineering,and other aspects of the southwestern Laizishan anticline,geological characteristics and prospecting direction of the deposit have been studied.It is showed that gold deposits in this area are distributed in the interlayer sliding structures,northeast trending fault structures,and secondary fault structures on both wings of Laizishan anticline.The ore deposit is generally controlled by interlayer sliding faults in the eastern wing of the anticline.It occurs in Permian Houziguan formation in a layered or quasi layered manner.The ore body has morphological characteristics of joint control of faults,faults and multi-layer lithological combinations.
