摘要
在寻找金矿中,物探方法的主要任务是:查明探矿的断裂带、破碎带和蚀变带;圈定含矿岩体和岩层;确定弱矿化带;寻找石英脉和其它含矿岩脉。重力、磁法、激电法、甚低频电磁法等常规方法均有良好效果。试验工作表明,压电法、射电法及较电激电法是很有前途的方法;研究岩石矿物的热电性和热致光特征是值得重视的,对于矿产预测及评价含金矿性都有积极作用。
Abstract
The main tasks of geophysical prospecting techniques in search for gold
deposits are detection of or--controlling fault zonesl fracture zones and altera-
tion zones, delineation of ore-bearing rock bodies and strata, determination of weak mineralization zones and search for quartz veins and other ore-bearing veins. Such traditional techniques as gravity, magnetic method, induced polari zation method and extremely low frequency electromagentic method all prove to be effective. Tests show that piezoelectric method, radio method and seis mic induced polarization method are quite promising. In addition, the study of thermoelectricity and thermoluminescent characteristics of rocks and mine rals is a new subject which deserves due consideration and will play an acti ve role in prognosis of ore resources and evaluation of ore potential.
