浙东南火山银矿成矿规律

本文综合了以往有关勘查和研究成果，总结浙江省江山—绍兴深断裂以南中生代火山岩区火山银矿床、点的时空分布、中型银矿床定位、成矿物质来源、成矿温度、矿石有用组分的垂直分带、矿物垂直分带、近矿围岩蚀变分带、矿体原生晕、稳定同位素、火山岩下的基本底物质组成差异与银矿的成矿关系等统计规律与成矿系列，认为浙东南火山岩区仍有良好的火山银（金、铅锌）矿找矿远景。

METALLOGENIC LAW OF VOLCANIC SILVER DEPOSITS IN SOUTHEASTERN ZHEJIANG

The paper synthesizes the previous relative results of geological explorationa and researches in southeast part of Jiangshan-Shaoxing deep fault of Zhejiang Province. It sumsup metallogenic series in Mesozoic Volcanic rock area, the space-time distribution of volcanic silver deposits (occurrence), the location of middle size silver deposits, origin of ore-forming materials, metallogenic ternperature, wallrock alteration zoning, vertical zoning of useful elements or minerals, protogenic haloes of orebody, stable isotope, the relation between the defferent basement matters under volcanic rocks and sivler deposits etc. It is considered that this area has good propeeting for volcanic silver (gold, lead-zinc) deposits.
