摘要:

吉林省长白玄武岩覆盖区位于重点成矿区带辽东—吉南成矿带北东段,围绕玄武岩覆盖区金、多金属矿床(点)星罗棋布。研究区内已发现典型矽卡岩型金矿床——八道沟金矿床,综合分析研究区地质特征,认为研究区具有寻找矽卡岩型金矿床的潜力。通过对高精度重力异常特征分析,在研究区内布置了重-磁-电-地综合剖面,对该综合剖面地球物理特征进行了总结,推测玄武岩盖层下碳酸盐岩与中酸性侵入岩的分布及接触位置。综合分析认为,重-磁-电-地综合剖面10110—10280点段与11400—11700点段2处具有寻找矽卡岩型金矿床的潜力。在研究区内进一步开展地球物理工作,有望实现玄武岩覆盖区的找矿突破。

Abstract:

The Changbai basalt-covered area of Jilin Province is located in the northeast section of the East Liaoning-South Jilin national key ore belt.A great deal of gold and polymetallic deposits are distributed around the basalt-covered area.A typical skarn type gold deposit—Badaogou Gold Deposit,is discovered in the study area.Based on comprehensive geological characteristics analysis of the area,it is deemed that the study area has prospecting potentials for skarn type gold deposit.Through high precision gravity anomaly characteristics analysis,a gravity-magnetism-electricity-ground comprehensive profile is arranged in the study area and summarized the geophysical characteristics of the comprehensive profile.The distribution of carbonatite and mid-acidity intrusion rock under the basalt-covered layer as well as their contact location is inferred.Comprehensive analysis takes that the gravity-magnetism-electricity-ground comprehensive profile 10110-10280 spot and 11400-11700 spot have prospecting potentials for skarn type gold deposits.Further geophysical work in the study area could lead to prospecting breakthroughs in basalt-covered area.
