摘要
通过对浙东南地区层状铅锌矿床之成矿地质背景、矿床地质特征及成矿物质来源的研究,指出本区展状铅锌矿床的形成,经历了三个成矿阶段:1.沉积成矿阶段,形成了矿源层及部分硫化物;2.火山气液或(和)火山热泉的改造成矿阶段,它促使矿源层进一步发展成为矿层;3.火山期后热液成矿阶段,该阶段对已形成之矿体作了些轻微的改造,并形成了少量的脉状矿体。从成矿条件、成矿物质来源及稳定同位素特征来看,本类矿床应属沉积-叠加型层控矿床。
This paper deals with investigations on the background, characteric features and source materialof the straform Pb-Zn ore deposits in the Southeast Zhejiang Province. Three metallogenic stages arerevealed i. e. (1) Sedimentary stage during which the ore source bed and some sulfides were formed;(2) Volcanic exholative and hot spring stage during which the source bed was reworked and some orehorizons took their shapes; (3) post volcano hydrothermal fluid stage during which some ore veins wereformed.
