吉林省东部早中元古界金矿集中区成矿特点及成矿远景

The metallogeuic features and prospects of the early-middle proterozoic gold concentration areas in eastern Jilin Province

吉林省东部早中元古界有三个较大的金矿(化)集中区集(安)通(化)、老岭、金(银别)海(沟)集中区,具有成矿局限性、矿石工艺复杂、有含金宇宙尘加入等局部特点,和层控性、多源性、与岩浆关联性、继承性、穿时性等区域特点。可划分出九个成矿带及两个潜在远景区。

: There are three larger early-middle prolerozoic gold concentration areas in eastern Jilin Province,namely, Ji' an-Tonghua, Laoling, Jinyinbie-Haigou concentration areas, which have the local features of ore-forming limitation,ore-processing complexity .auriferous cosmic dust contamination and the regional features of stratabounding, multiple source, magma-relation, inherence, diachronism etc. They may be divided into nine mineralization bells and two potential prospective areas.It is initially estimated to be a better prospect and high potential area for ore-finding.
