摘要
本文从构造变形分析入手,论述了金顶矿床构造形成和演化的特征,探讨了铅锌矿化富集的规律,提出成矿作用主要表现为建造形成期的同生沉积带来了成矿元素并使其初步富集,而构造变形期则由于断裂沟通地下热卤水和天水的渗透,使其成矿物质运移到受推覆构造和穹隆构造控制的高孔隙度、高渗透率的砂岩、角砾岩和构造剥离带而富集成矿。
On basis of the analysis of tectonic deformation, this article demonstratescharacteristics of the tectonic initiation and the tectonic evolution of the Jinding lead-zinc deposit,studies the regularity of mineralization concentration,and proposes the model of mineralization process on the metallogenic elements and their preliminary concentration during the sedimentary formation. And the filtration of the ground thermal brine and the atmospheric water nearby the faulted zone caused the mineralizing materials to move and concentrate in sandstone and breccias with high porosity and high permeability and in the tectonic exfoliation belt, which are controlled by the thrust-nappe and dome structures.
