摘要
五莲七宝山地区已发现中型金铜矿1处、中型多金属矿1处,属陆相火山热液型矿床,近年来在该地区完成了一系列勘查工作,取得了新的找矿成果。区内金铜及多金属矿与七宝山次火山杂岩体活动十分密切,次火山侵入岩能引起高磁异常,金铜矿、方铅矿、闪锌矿能引起可控制音频大地电磁(CSAMT)低阻异常,研究发现七宝山金铜矿物探异常特征为低磁、CSAMT低阻。结合前人短红外光谱蚀变测量,确定了七宝山热液中心。上述综合找矿信息,为金铜矿深部外围找矿中发现新的含金铜及铅锌矿体指明了方向。
One medium sized gold and copper deposit and one medium sized polymetallic deposit have been discovered in Qibaoshan area in Wulian county.It is a terrestrial volcanic hydrothermal deposits.In recent years,a series of exploration work have been completed,and new prospecting achievements have been achieved.The gold,copper and polymetallic deposits are closely related to subvolcanic complex rock activity in Qibaoshan area.Subvolcanic intrusive rocks will cause high magnetic anomalies,while gold,chalcopyrite,galena and sphalerite will cause controlled source audio magnetotelluric(CSAMT)low resistance anomalies.It is found that anomalous characteristics of Qibaoshan gold and copper deposit are low magnetic and CSAMT low resistance.Combining with previous short infrared spectrum alteration measurements,it is determined that Qibaoshan area is the hydrothermal center.It will provide comprehensive exploration information for discovering gold,copper and polymetallic ore bodies in the deep surrounding areas of gold and copper deposit.
