摘要
新疆金沙滩金矿普查区以往的物探资料相对缺乏,这与该区较为困难的接地条件有关。相对而言,双频激电法具有受电流变化影响小、抗干扰能力强等优点,对该类地区的物探找矿具有一定的适用性。文章主要阐述了双频激电中梯扫面和双频激电测深在新疆金沙滩金矿普查区的应用;并通过视幅频率的数据处理,综合分析双频激电中梯平面、剖面异常特征和双频激电测深断面特征,进一步明确找矿范围,查明矿(化)体的赋存部位、分布规模等,实现找矿目标。
The geophysical exploration data for the Jinshatan gold deposit area in Xinjiang is rare because of the large resistance of the ground surface material. The dual frequency induced polarization （IP） method which include the dual frequency IP interme diate gradient method and the dual frequency IP sounding method is adaptive to this area for its advantages of slightly subjected to the change of current intensity and strong anti interference ability. In this paper, the application of the dual frequency IP intermediate gradient and the dual frequency IP sounding methods to the Jinshatan gold deposit area are discussed. The survey data are processed in apparent amplitude frequency plane, meanwhile, the ORE features in apparent amplitude frequency plane for both dual frequency IP intermediate gradient and dual frequency IP sounding methods are summarized, these features are critical for the ORE identifying while using the dual frequency IP method.
