大兴安岭南段铜多金属矿成矿时空结构

成矿时空结构是将成矿的构造体系、流体系统及矿床定位结合,从时间演化的角度来考察矿床(体)的三维空间分布规律及其与储控矿因素之间的内在联系的结构关系.对大兴安岭南段铜多金属矿床成矿系统构造演化规律、铜多金属成矿带-锡铅锌铜矿带-铅锌铜矿带的空间展布格局、由燕山早期向中晚期演化的成矿时序结构、二叠系基底岩系和燕山期岩浆岩组成的"二元物质结构"等方面的综合研究,这四者的有机结合构成了大兴安岭南段铜多金属矿的成矿时空结构.

The metallogenic space-time structure of copper-polymetallic deposits in the southern segment of Da Hinggan Mountains, China

The metallogenic time-space structure of a mineral deposit is a combination of the tectonic system, fluid system and location of a deposit. It describes the spatial distribution pattern of the mineral deposit and the structural relationship of the inner link between the pattern and many main ore-controlling factors in the light of time evolution. The paper synthetically analyses many characteristics of copper-polymetallic deposit metallogenic systems in the southern segment of the Da Hinggan Mountains, such as the tectonic evolution regularity, the spatial distribution pattern from copper-polymetallic ore belt to tin-lead-zinc-copper polymetallic ore belt to lead-zinc-copper polymetallic ore belt, the temporal sequence structure from early Yanshanian period to middle and late Yanshanian period, the dualistic mineral structure of the Permian base rock series and the Yanshanian magmatite. The organic combination of the four characteristics makes up the metallogenic time-space structure of copper-polymetallic deposits in the southern segment of the Da Hinggan Mountains.
