| 摘 要： | 大架金矿床位于吉林省桦甸市夹皮沟金矿田南部溜河地区，属蚀变岩型金矿床。受六批叶NW向韧脆性剪切带及后期脆性构造控制，与印支期岩浆活动及脉岩有时空成因联系；具有矿体多、矿化均匀、厚度较稳定和埋藏浅等特点。该矿床产出地质环境及地质特征在吉南地区有一定代表性，并突破了“太古宙高级变质区内无大矿的传统观念”。

| Abstract: | Locating at the southern Jiapigou gold deposit,Jilin Province,Dajia gold deposit is an altered rock-type gold deposit controlled by Liupiye NW brittle-ductile shearing belt and after brittle structure,and has a time-space relation with the magmatism and veins of Indo-Chinese epoch.The deposit shows such characteristics as rich orebody,uniform mineralization,less variable thickness and low embedded depth,etc.The geological environment and features are typical in south Jilin Province.The conclusion denies the traditional idea that there is no large gold deposit in well-altered rock of Archean epoch. |
