摘要
矿床时空四维结构模型是对矿床(体)与诸主要控矿因素时空配置关系的描述,它基于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诸控矿因素之间的内在联系的结构关系,它是矿床模型研究的重要前沿问题之一。本文通过对康古尔金矿床中矿体的形态空间展布及控矿构造型式、成矿阶段、成矿物质来源、成矿时代等方面的综合研究,提出火山岩、韧性挤压变形带、同构造花岗岩体、晚期韧-脆性正断剪切带是矿床金成矿的四个重要地质条件,这四个控矿因素同位一体是康古尔金矿床的时空四维结构模型。
The time space four dimensional structural model of a mineral deposit is a generalization of time space disposition relationship between a mineral deposit (or orebody) and many main ore controlling factors. It describes the spatial distribution pattern of a mineral deposit (or orebody) and the structural relationship of inner link between the pattern and many main ore controlling factors in the light of time evolution, thus serving as one of the important forefront research subjects of the mineral deposit model. Based on synthetic analysis of many characteristics of the Kanguer gold deposit, such as its shape and spatial distribution of gold orebodies, the ore controlling structural pattern, stages of mineralization, material sources and the metallogenic epoch, the authors have found that the volcanic rocks, the ductile compressive deformation zone, the syntectonic granite and the later ductile brittle normal shear zone constitute four important metallogenic geological prerequisites, and the four ore controlling factors in one body make up the time space four dimensional structural model of the Kanguer gold deposit.
