摘要
现阶段常用于地质探测的方法有多种,瞬变电磁法作为其中的一种常用方法,一直以来适用于较厚松散沉积地层的探测,在基岩埋深较浅的情况下很少使用。本文选取青藏高原一处特殊地质条件下的区域作为研究区,根据初步调查资料,该区域基岩埋深浅,为使用瞬变电磁法进行探测提供了有利条件。为了保证探测结果的可靠性、全面性,在以瞬变电磁法为主的基础上,还结合了构造特征、钻孔岩心和地温监测数据,在后期进行数据分析时作为参考。
At present,there are many methods commonly used in geological exploration.As one of the common methods,transient electromagnetic method has always been suitable for the detection of frozen soil in thick loose sedimentary layer,and rarely used in the case of shallow bedrock.In this paper,a special geological condition area of the Qinghai Tibet Plateau is selected as the study area.According to the preliminary survey data,the bedrock depth in this area is shallow,which provides favorable conditions for the use of transient electromagnetic method for exploration.In order to ensure the reliability and comprehensiveness of the detection results,based on the transient electromagnetic method,combined with the structural characteristics,drilling core and geothermal monitoring data,it can be used as a reference in the later data analysis.
