云南省龙陵县勐糯铅锌矿构造控矿因素分析

勐糯铅锌矿位于保山市龙陵县勐糯镇勐糯向斜的东翼,矿床主要呈近南北向展布,受地层、岩性及构造控制明显,矿区在构造控矿方面研究几乎空白,本文结合矿区研究的薄弱环节,在总结前人资料和大量的野外地质调查工作基础上,完成对勐糯铅锌矿矿区构造特征、矿区构造应力场演化、构造期次划分、不同类型构造控矿作用、构造应力场演化与成矿作用关系的分析,并建立勐糯矿区构造-沉积-成矿模式和构造-岩浆-成矿模式,填补了矿区构造控矿研究的空白。

Analysis on structural ore-controlling factors of Mengnuo lead-zinc mine in Longling County, Yunnan Province

Mengnuo lead-zinc mine is located in the east wing of Mengnao syncline in Longling County, Baoshan City. The deposit is mainly distributed in the north and south direction and is obviously controlled by strata, lithology and structure,and there are almost no research on structural ore control in mining area.On the basis of summarizing the previous data and a lot of field geological survey work, this paper combines the weak link of mining area research, completes the structural characteristics, tectonic stress field evolution and tectonic period division of Mengnuo lead-zinc mine area. The analysis of the relationship between the evolution of tectonic stress field and mineralization in different types of tectonics, and the establishment of tectonic-deposition-metallogenic model and tectonic-magmatic metallogenic model in Mengnuo mining area filled the blank in the study of tectonic ore-control in ore area.
