德勒诺尔铁矿赋矿地层形成时代为中元古代,其后经历过多期多次构造叠加作用,变形变质作用较为复杂。成矿期后的断裂、褶皱、节理等构造十分发育,受褶皱和断裂构造的影响,矿体的空间形态和产状极其复杂,给钻探工程部署造成很大困难。本文在地面磁测数据处理、转换及构造增强的基础上,对其所蕴含的深部构造信息进行了提取和解释,初步建立起了矿区的基本构造格架,揭示了不同期次、不同方向、不同性质的构造对矿体的控制作用,较好地解决了矿体形态复杂的找矿难题,有效提高了钻探工程的见矿率。
The formation age of the ore-bearing strata of the De Lenoer iron orefield is the Mesoproterozoic, and then undergoes superimposition of multiple tectonics for many times since. The metamorphism and metamorphism are complicated. The structure of faults, folds and joints after the metallogenic stage is well developed. Due to the influence of folds and faults, the spatial shape and shape of the orebody are extremely complicated, which makes it very difficult for the drilling project to be deployed. Based on the processing, transformation and enhancement of terrestrial magnetic data, the paper extracts and interprets the deep structural information that it contains, and initially establishes the basic tectonic framework of the mining area. It reveals the characteristics of different stages, different directions, Different structure of the control of the ore body to better solve the complex ore prospecting problems and effectively improve the seepage rate of drilling projects.
