摘要
为了解决物探在寻找隐伏铝土矿上的难题,对华北地台的河南陕-渑-新、嵩-箕及鲁-宝-临铝土矿成矿区作了直流电法寻找铝土矿的试验。阐述了工作区内铝土矿成矿的沉积特征和铝土矿的地球物理特征。在该项工作的阶段性总结的基础上,简要介绍了定性解释法、干扰因素的识别和排除法、定量解释法、物探划地层法、识别地堑、地垒的"分散圈"法、物探剥地层法以及λ值法等关键技术在找矿实践中的应用。
In order to find a solution to search for the concealed bauxite deposit by geophysical prospecting, a test has been made in Shan-Miao-Xin, Song-Qi and Lu-Bao-Lin bauxite ore zone with DI method.The paper discussed the sedimentary and geophysical characteristics of the bauxite deposit in the working area. The application of key techniques in ore prospecting was briefly introduced on the basis of the sum-up of the temporary work, including qualitative explanation method, discrimination and elimination of interference factor, quantitative explanation, geophysical stratum classification,rift valley indetification, horst outlining, geophysical stratum stripping and λ value method etc.
