英文摘要	大兴安岭是我国北方一个重要的多金属成矿带。本文从成矿的物质来源和构造作用两方面讨论大兴安岭的成矿系统。Sr、Nd、O、Pb同位素的研究显示大兴安岭成矿物质的深部来源,大兴安岭晚中生代壳幔混熔花岗质岩石组成及其构造环境的研究,表明它们是在板内非造山的伸展环境下形成的A型花岗岩。与南岭花岗岩及其成矿作用的对比研究,将加深对大兴安岭中生代成矿特征的认识。深部构造特征也进一步印证了大兴安岭的成岩-成矿的背景。; The Da Higgan Mts. is an impotent polymetallic mineralized zone in the north part of China, This paper discusses the metallogenetic system of the Da Higgan Mts. according to the source of its metallogenic materials and its tectonic settings. Sr-Nd-O-Pb isotopic researches show a deep source of the metallogenic materials in the Da Higgan Mts., and studies on composition of the Late Mesozoic crust-mantle migmatitic granitic rocks in the Da Higgan Mts. and their structural environment indicate that they are A-type granitic rocks formed in an intraplate and non-orogenic extensional environment. Understanding of the Mesozoic metallgenetic characteristics of the Da Higgan NI is. is deepened through comparison with Nanling granitic rocks and its mineralization. The deep structures of the Da Higgan Mts. further reveal its tectonic background of lithogenesis and mineralization.; http://gateway.webofknowledge.com/gateway/Gateway.cgi?GWVersion=2&SrcApp=PARTNER_APP&SrcAuth=LinksAMR&KeyUT=WOS:000276676700001&DestLinkType=FullRecord&DestApp=ALL_WOS&UsrCustomerID=8e1609b174ce4e31116a60747a720701 ; SCI(E); 中文核心期刊要目总览(PKU); 中国科技核心期刊(ISTIC); 中国科学引文数据库(CSCD); 19; 03; 649-656; 26
