探讨河南省栾川钼钨铅锌银多金属矿集区内不同矿床类型、不同成矿作用之间的内在联系。S、Pb、C、H、O 同位素及流体包裹体研究表明，研究区内不同类型矿床具有统一的物质来源，成矿流体是由斑岩体中心向外不断演化的岩浆热液流体体系。区内不同类型矿床均为晚侏罗世-早白垩世（162～131 Ma B．P．）岩浆热液活动的产物，钼钨铅锌银多金属成矿系统以晚侏罗世花岗斑岩体为中心，由中心向外分为中心成矿带（斑岩-矽卡岩型钼钨矿床）、过渡带（矽卡岩型硫锌多金属矿床）和边缘成矿带（热液型铅锌银矿床）。由中心向外，成矿时代具有由老到新的变化趋势，矿物组合和蚀变类型具有由高温到低温变化的特征，成矿流体具有由高温-高盐度岩浆热液流体向中低温-低盐度流体演化的趋势，晚期大气降水加入特征明显。由于不同成矿元素地球化学性质的差异和成矿流体运移路径上物理化学条件的不同，富含成矿物质的深源岩浆热液流体在斑岩岩浆热动力驱动下，形成了一个以燕山期花岗斑岩岩浆侵入活动为中心，时空密切关联的钼钨铅锌银多金属成矿系统。

This paper discusses the internal relation between the different types of deposits and between the different mineralizations in Luanchuan Mo-W-Pb-Zn-Ag polymetallic metallogenic concentration area.The reasearches of the S,Pb,C,H,O isotopes and fluid inclusions show that the different types of deposits share the ore source.The ore-forming fluid is the magmatic-hydrothermal fluid evolution continuously from the porphyry center and mixes with the meteoric water in the later period.The different types of deposits in Luanchuan are the products of the magmatic-hydrothermal mineralization in Late Jurassic-Early Cretaceous (162~131 Ma B.P.).The polymetallic metallogenic system takes the porphyritic pluton as the centre and is zoned into three metallogenic belts from the porphyry center outwards.The porphyry-skarn type Mo-W deposits in the core belt,the skarn type S-Zn polymetallic deposits in the middle belt,and the hydrothermal type Pb-Zn-Ag deposits in the periphery belt,respectively.From the center outwards,the mineralogenetic epochs trend from old to new,the mineral assemblage and alteration type have the characteristics varying from high temperature to low temperature,and the ore-forming fluid has the characteristics varying from the high temperature and high salinity magmatic-hydrothermal fluid to the middle(low)temperature and low salinity fluid.The deep magmatic-hydrothermal fluid is induced by the thermo dynamics of the granitic magma and due to the different metallic elements'geochemical characteristics and the different physical-chemistry conditions of the ore-forming fluid migration pathway,forms the Mo-W-Pb-Zn-Ag metallogenic system taking the Yanshanian granite-porphyry magmatic intrusion as the centre.
