玲珑金矿田东风矿区深部构造叠加晕研究

Research on the Structural Superimposed Halo in Dongfeng Mining Area of Linglong Gold Deposit

摘要:

东风矿床主要赋存于坡头青主断裂下盘的蚀变带中。在野外地质工作的基础上，运用数学地质分析方法，系统研究了构造叠加晕的特征，建立了构造叠加晕的理想模式。矿区构造叠加晕分析结果显示，金矿成矿具有多期、多阶段的特征，通过研究该区原生晕轴向分带特征，识别出不同成矿阶段所形成的矿体（晕）在空间上具有前尾晕共存的叠加结构，该结构是深部盲矿预测的重要依据。

Abstract:

Dongfeng deposit locates in the alteration zone in the lower part of Potouqing main fault. Based on field geological work in Dongfeng mining area, using geo-mathematic analysis, characteristics of structure superimposed halo.have been studied, and the ideal model of structure superimposed halo has been set up. As showed by the structure superimposed halo of the mine, it is found that the mineralization have the characteristics of multi-period and multi-stage. Through the study on the halo axial zoning characteristics, the ore bodies （halo）formed in different mineralization stages have the characteristics of coexistence of head and tail halo. This structure is an important basis for blind orebody predication in deep part.
