摘要
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。
Formation and distribution of lead-zinc deposits in the Fengtai mineral cluster region are clearly controlled by various geological factors which always lead to ore formation with inherent genetic and spario-temporal relationship. Based on deep analyzing of the metallogenic geological characteristics for leadzinc, space-locating rule of orebodies has been researched under the guidance of great geological events generated ore theory and modern mineralization theory, starting with the analysis of the spatio-temporal structure that lead-zinc mineralization in the region. The results show that mineralization is closely related to great geological events, characterized by many mineralization stages. Spatially, a structure of ＂one region divided into-two belts and four centers＂ has been formed,with orebodies distributed along lithologic interface , enriched in the turn end of subordinate anticline and gained a lateral trending in opposite direction.
