四川代隆金矿床地质特征及成因探讨

代隆金矿床自发现至今，地质找矿还处于预查阶段，通过对代隆金矿床区域地质、矿区地质、矿体地质特征、成矿物质来源以及成因等的探讨，得出了矿床赋存于上三叠统新都桥组中，矿体受岩脉、构造控制；矿石类型为破碎蚀变板岩型和花岗斑岩型2种；主要的载金矿物为黄铁矿、毒砂以及辉锑矿；成矿物质来源为地层和岩浆双重来源，成矿温度属中温范围，成矿世代为晚三叠世-早侏罗世，矿床类型属中温热液蚀变岩型。以上结论为进一步研究该矿床的成矿规律，指导下一步地质找矿工作的开展提供了参考。

Geological Characteristics and Genesis of Dailong Gold Deposit in Sichuan Province

Dailong Gold deposit was found in 2005，but geological prospecting is still in pre-investigation stage. Through the researching of regional geology background，deposit geology，material source and genesis，the conclusi-on is that orebodies which is hosted in Upper Triassic Xinduqiao group is controlled by the rock and tectonic；the ore type is the broken alteration slate and granite porphyry；the main gold-bearing minerals are pyrite，arsenop-
yrite and stibnite；ore-forming material is from strata and magma，having the medium temperature range；metallogen-
ic epoch is Late Triassic-Early Jurassic；type of Dailong gold deposit is the mesothermal alteration.This study provi-
des reference for the further research on the metallogenic characteristics and the geological prospecting activities.
