摘要
为解决铜山口老矿区深部及外围找矿重大突破的技术难题,以重力调查方法为主,配合磁法及电法勘探,在铜山口地区开展了深部找矿方法技术研究。根据该地区热液型多金属矿床的成矿规律,建立了该地区地质—地球物理找矿模式。这对在长江中下游地区寻找与中酸性侵入岩有关的矽卡岩型和斑岩型铜、铁、钼等矿床具有一定的指导意义。
For the purpose of solving the difficult technical problem of making important breakthrough in deep and peripheral ore-pros- pecting work of the Tongshankou old mining area, the author mainly used gravity survey in combination with magnetic and electrical ex- ploration to conduct researches on deep ore-prospecting methods and techniques in Tongshankou area. A geological-geophysical ore- prospecting model for this area was established on the basis of the metallogenic regularity of hydrothermal polymetallic ore deposits in this area. The results obtained are of some guiding significance in search for copper, iron, molybdenum and some other kinds of ore de- posits related to intermediate-acid intrusive rocks in the middle and lower reaches of the Yangtze River.
