陕西凤太地区寻找优势矿种铅锌金的有效方法

Effective Method for Finding the Lead-zinc and Gold-Preponderant Mines in Fengtai Area

凤太地区是我省重要的铅锌金矿集中区,也是寻找铅锌金矿的热点地区,具备有寻找铅锌金矿的潜力和条件。在寻找深部隐伏铅锌矿和金矿方面积累了大量的经验和教训,也取得了重大突破。寻找隐伏铅锌矿最有效的方法就是沿着矿体、含矿地层、控矿背斜顺藤摸瓜循序渐进。凤太地区近四十年左右的时间找了三个金矿（太白金矿、四方金矿（也叫八卦庙金矿）、庞家河金矿）,累计探明黄金资源量近200 t,三大金矿的发现都是化探异常提供的线索。找金矿的有效方法,先用化探次生晕扫面,有异常再用化探分散检查定位,再用化探原生晕地化剖面进行检查确认,用化探方法检查验证化探异常最终达到找矿的目的,投资少、见效快、简单易行、效果好。

Fengtai area is our important region focused on the lead-zinc and gold, ant it is also a hot spot district for seeking the lead-zinc and gold which have the big potential and good condition for prospecting the lead-zinc and gold deposits. Here we accumulated a lot of experiences and moral in searching for the deeply-burried lead-zinc and gold, and also make a significant breakthrough. The most effective method for prospecting the deeply-burried lead-zinc mines is make a deeper investigation and proceed in an orderly ways along the ore body, mineralized stratum, mineral-controlled anticline. Here in Fengtai area three gold mines had been explored in forty years, they are Taibai, Sifang and Pangjiahe gold deposits. The measured gold resources in accumulative total is nearly 200 tons. These three gold mines were found by the clue of geochem- ical anormals. The effective method for gold-finding is geochemical secondary halo scanning in first, and geochemical dispersion trains check when find the normals in second, and confirm with geochemical primary halo in third, and verify with geochemical method in the end. These four steps can achieve the purpose of ore prospecting which have the characteristic s of less-investment, operate quickly and easy-to-accomplish steps.
