摘要
通过对彩霞山重力场平面特征的研究,确定了控矿大理岩的分布和范围,间接探索了与控矿大理岩相关的铅锌矿体分布区段。通过对重力剖面的研究,发现铅锌矿体赋存于高密度板体上或紧邻一侧。通过可控源音频大地电磁法(CSAMT)的研究,发现"半椭圆状"、"椭圆状"高阻异常反映了控矿大理岩或蚀变带相关的控矿体。上述特征得到浅部钻探的验证,在找矿中发挥了积极的作用。又应用此模式进行深部矿体的分析预测,并得到了深部钻探验证。
By studying on the characteristics of gravity in Caixia Mountain, the author discovered the distribution and extent of the ore marble, and indirectly explor the distribution of lead and zinc related to ore marble. Through the study on gravity profiles, be found Lead - zinc occurrence on high - density body or near the side. Through the study on CSAMT , he also found that ＂half oval - shaped＂ , ＂oval - shaped＂ high resistance anomaly reflects the ore marbleor alteration associated with ore. These characteristics was verified by shallow drilling, and played a positive role in prospecting. And applying this model, people can predict the deep ore body, and a drilling has been verified.
