陕西凤太矿集区铅锌矿床的形成与分布明显受控于各类致矿地质因素,并显示一定的内在成生联系和时空配置关系。在深入分析区内铅锌成矿地质特征的基础上,以重大地质事件致矿理论和现代成矿作用理论为指导,从铅锌矿化的时空结构分析入手,系统研究了矿体的空间定位规律。研究结果表明,在时间结构上,成矿与重大地质事件密切相关,具有多期次多阶段成矿的特点;在空间结构上,形成了“一区二带四中心”的基本矿化格局,矿体沿岩性界面分布,在次级背斜转折端富集,南、北两矿带相背侧伏。
The formation and distribution of lead-zinc deposits in the Fengtai ore-gathering area in Shaanxi Province are obviously controlled by various geological ore-forming factors and show some inherent relationships and temporal and spatial distributions. Based on the in-depth analysis of the geological characteristics of lead-zinc mineralization in the area and under the guidance of the ore-forming theory of major geological events and the theory of modern mineralization, the spatio-temporal structure of lead-zinc mineralization is analyzed. law. The results show that in terms of temporal structure, the mineralization is closely related to major geological events and has multi-stage multi-stage mineralization. In the spatial structure, the basic mineralization of “one zone, two zones and four centers” is formed Pattern, ore body distribution along the lithological interface, enrichment at the turning point of the secondary anticline, south and north of the two sides of the back volts.
