采用V8多功能电法工作站在河南新安石寺—北冶地区铝土矿调查评价项目中进行可控源音频大地电磁测深(CSAMT)。CSAMT法凭借其抗干扰能力强、探测深度大、资料解释手段成熟等特点,在铝土矿调查评价项目中起到了至关重要的作用。它清晰地反映了调查区铝土矿含矿目标层、奥陶系古风化壳形态沿走向的变化情况以及地层的产状,为地层的划分及后续铝土矿调查评价工作提供了深部电性信息,为钻孔布设和矿产预测提供了依据。
The V8 multi-function electric method workstation was used to conduct controllable source audiotelemetric electromagnetic sounding (CSAMT) in the project of bauxite survey and evaluation in Shi’an-Beiye area, Xin’an, Henan. The CSAMT method plays a crucial role in the project of bauxite survey and evaluation by virtue of its strong anti-interference ability, large exploration depth and mature data interpretation methods. It clearly reflects the change of the ore-bearing target layer of the bauxite in the study area along the strike of the Ordovician paleo-weathering crust and the occurrence of strata, providing deep electrical properties for the stratigraphic division and subsequent investigation and evaluation of bauxite The information provided the basis for drilling layout and mineral prediction.
