摘要
长江中下游地区是我国重要的金属矿床成矿带,姚家岭铜铅锌矿床是近年来在长江中下游地区发现的大型矿床。文章通过收集和分析姚家岭铜铅锌矿的实际勘探资料,使用Surpac三维建模软件对姚家岭矿床的矿体及相关围岩的空间位置数据建立相应的地层和矿体三维模型。地层及矿体的三维形态表明姚家岭铜铅锌矿的控矿构造明显受到印支期和燕山期2期相互近垂直的构造应力的作用,其记录了中生代特提斯构造体制与太平洋构造体制转换的过程,符合长江中下游转换构造结内具有的结点成矿规律。
The middle-lower Yangtze River area is one of the most important metallogenic belt in Chi- na. The Yaojialing Cu-Pb-Zn deposit is a newly-discovered ore deposit in the middle-lower Yangtze River area. By collecting and analyzing the actual exploration data of Yaojialing Cu-Pb-Zn deposit, the strata and ore body 3D models of Yaojialing deposit are built based on the strata data of Yaojialing de- posit and the data of space position of related wall rock by using Surpac 3D modeling software. The 3D structure models show that the ore-controlling structure in Yaojialing Cu-Pb-Zn deposit is the re- sult of mutually nearly vertical tectonic stress in Indosinian and Yanshanian periods. It records the tectonic regime transition process between Tethys and Pacific tectonic regimes. Node-type mineraliza- tion can be found within the structural knots of the middle and lower reaches of Yangtze River.
