三叠纪构造演化在中国地质历史过程中具有强度大、影响广泛的特点,然而与三叠纪重大构造事件有关的成矿作用研究明显滞后。本文基于最新研究成果,初步系统论述了中国三叠纪大规模成矿时空分布及基本特点。中国三叠纪金属矿产主要分布在昆仑—秦岭和红河—哀牢山两个三叠纪主造山带及其邻区,另外在华南、东北和新疆三个板内也发育有一系列多金属矿产。三叠纪矿床类型主要包括：①与基性-超基性岩有关的Cu-Ni硫化物矿;②与中酸性-酸性岩有关的斑岩Cu-Au、Cu-Mo、Mo矿,矽卡岩型Cu-Pb-Zn、Cu-Fe、Sn、W矿和脉状Au矿;③与高温气液-流体有关的伟晶岩型稀有金属矿;④与造山过程构造-热-流体有关的造山型Au矿;⑤与造山过程盆地流体有关的MVT型Pb-Zn矿;⑥与地幔流体有关的碳酸岩脉型Mo矿。昆仑—秦岭造山带内大多数三叠纪矿产都形成于碰撞造山或后碰撞环境,以前者为主。在东秦岭地区,三叠纪矿床以Mo、Au矿为主,形成时代集中在233～221 Ma;西秦岭地区三叠纪Au矿和Pb-Zn矿广泛分布,其中金矿受北西向脆韧性剪切构造带控制,而Pb-Zn矿集中出现在西成和凤太两大盆地内,成矿时代集中在晚三叠世（232～214 Ma）;东昆仑地区新探明的一系列Cu-Mo-Fe多金属矿床,其成矿时代为240～210 Ma。红河—哀牢山造山带受新特提斯构造演化影响,三叠纪矿产呈零星出露,主要出现在中甸古岛弧区、造山带东侧的滇黔川接壤区和滇东南都龙地区。在中甸岛弧区整体表现为中部以斑岩-矽卡岩型Cu矿床为主,向南北两侧变为斑岩-浅成低温热液型Cu-Pb-Zn矿床和Au矿床,成岩成矿年龄集中于228～201 Ma;川滇黔地区近几年的测年结果显示出其主要的Pb-Zn矿都形成于三叠纪;滇东南都龙地区新近发现一组三叠纪W-Sn矿床,成矿时代集中在214～209 Ma。除两条主碰撞带外,三叠纪矿床还有华南稀有

英文摘要：

Triassic tectonic evolution in China is characterized by high intensity and wide influence.However,the metallogenic study related to the major Triassic tectonic events has obviously been lagging behind.This paper preliminarily and systematically discusses the space-time distribution and basic characteristics of the large scale Triassic mineralization in China based on the latest research achievements.Triassic deposits in China are distributed mainly in the two main Triassic orogenic belts of the Kunlun-Qinling orogenic belt and the Red River-Ailaoshan orogen belt and their adjacent regions;Besides,there are a series of polymetallic deposits developed in the three intraplates of southern China,northeastern China and Xinjiang area.Major types of Triassic deposits mainly include： ① Cu-Ni sulfide deposits related to basic-ultrabasic rock;② porphyry Cu-Au,Cu-Mo,Mo deposits,skarn Cu-Pb-Zn,Cu-Fe,Sn,W deposits and vein-type Au deposits related to intermediate-acid rocks and acidic plutons;③ pegmatite-type rare metal deposits related to high temperature gas-fluids;④ orogenic Au deposits related to tectonic-hydrothermal activities in the orogenic process;⑤ MVT Pb-Zn deposits related to basinal fluids in the orogenic process;⑥ carbonated vein-type Mo deposits related to mantle fluids.Most of the Triassic deposits in the Kunlun-Qinling orogen belt were mainly formed in collisional stage,or in the post-collision setting.In East Qinling area,the Triassic deposits are dominated by Mo,Au,with the formation ages mainly concentrated in 233-221Ma.In contrast,Au deposits and Pb-Zn deposits of Triassic are widely distributed in West Qinling area,Au deposits are distributed along the NW-trending brittle-ductile shear zones,and Pb-Zn deposits are largely concentrated in the two targe basins of Xicheng and Fengtai,whose metallogenic epochs are mainly in the Late Triassic（232-214Ma）.In East Kunlun area,newly discovered Cu-Mo-Fe polymetallic deposits were formed in 240-210 Ma.Influenced by Neo-Tethys evolution,Triassic m
