根据吉林省通化二密铜矿资源潜力宏观评估的三项标志:其一成矿时代为130～100Ma,系中国东部最为重要的燕山期成矿事件组成部分;其二成矿边缘受拉分—张裂复合火山盆地的构造系统和次火山岩侵入构造叠加所制约,具有多重成矿边缘;其三成矿流体为与安粗岩系岩浆活动有关的含矿流体,有极好的铜、金等成矿元素的专属性。因此,应存在较大、较好的找矿空间。本着“找矿先找岩体,评价岩体优先评价岩体边界”的找矿方针,不仅可在矿区内对已知的三期岩体“探边摸底”寻找隐伏岩体和盲矿体;还可以在矿区外马鹿沟—曙光、大西岔—黎明等两条北西向花岗斑岩小侵入体岩群及可能发现的火山机构开展找矿工作。
According to the macroevaluation of Tonghua Bismuth Mine resource potential in Jilin Province, the three indicators are as follows: the first metallogenetic age is 130-100 Ma, which is the most important component of the Yanshanian metallogenic event in eastern China; the second metallogenic margin is affected by the pull- There are multiple ore-forming margins in the tectonic system of the Zhangjiahe composite volcanic basin and superimposition of sub-volcanic intrusive tectonics. The third ore-forming fluid is a ore-bearing fluid related to the magmatic activity of the burnt rock series and has excellent copper, gold, etc. Exclusiveness of ore elements. Therefore, there should be larger, better prospecting space. Based on the prospecting principle of “looking for rock mass first, evaluating the priority of rock mass to evaluate the rock mass boundary”, we can not only search for the hidden rock mass in the mining area for the known phase III rock mass And blind orebodies. It is also possible to carry out prospecting work in two small intrusive granitoids in the northwestern granite porphyry and other volcanic structures outside the Mugu deer-Dawning, Daxifu-Dawn, and other places.
