根据作者对沃溪矿区含矿石英脉比较全面、系统的观察研究,本文从脉体的产状、劈理、小褶皱、构造透镜体、香肠构造等方面,叙述了脉体弯曲与围岩拱曲有相似的几何特征,它们是在同一挤压力作用下发生拱曲形成的。文中应用赤平投影,说明它们形成与褶皱生因关系。同时,利用趋势面分析,阐明矿区的褶皱与矿化的关系。提出本区富矿柱的延但主要是在倾伏背斜翼部次一级挠曲部位,矿体增厚也产生在褶皱翼部。
According to the author’s comprehensive and systematical observation on the ore-bearing quartz veins in the Woxi mining area, this paper describes the characteristics of veins bending and surrounding rock arches in terms of the occurrence, cleavage, small folds of the veins, the structure of lens bodies and the structure of sausages, Songs have similar geometric characteristics, they are under the same squeezing force arching occurs. The application of stereopair projection, the formation of their relationship with the fold causes. At the same time, the trend surface analysis is used to clarify the relationship between the fold and mineralization in the mining area. It is proposed that the prolongation of the ore-bearing pillar in this area is mainly in the secondary flexural part of the plunging anticline wing. The thickening of the ore body also occurs in the fold wing.
