Combining multiple components of InfiniTEM® electromagnetic data to better represent subsurface anomalies

Abitibi Géphysique，inc.，从现有技术中开发出一种名为InfiniTEM®的新系统，用于矿产勘探。该系统旨在定位和描绘加拿大的金属矿床。InfiniTEM系统是一种时域电磁系统。时变电流在布置在地面上的发射器回路中流动。该时变电流产生时变磁场，并且该磁场感生电流以在具有相对高的电导率的地质特征（诸如金属矿床）中流动。感应电流的影响可以在地表感知，从而揭示矿体的存在。导电地质特征的存在以复杂的正负特征的形式在InfiniTEM数据中表现出来。非专业人士很难解释这种签名。因此，该项目的目标是开发一种数据处理技术，将导体的复杂偶极InfiniTEM特征转换为单个，简单，一致的峰值。

Abitibi Géophysique, inc., have developed from existing technology a new system, called InfiniTEM®, for mineral exploration. The system is designed to locate and delineate metallic ore deposits in Canada. The InfiniTEM system is a time-domain electromagnetic system. A time-varying electric current flows in a transmitter loop laid out on the ground. This time-varying current creates a time-varying magnetic field, and this magnetic field induces electric currents to flow in geological features, such as metallic ore deposits, that have relatively high electrical conductivities. The effects of the induced currents can be sensed at the surface, thus revealing the presence of an ore body. The presence of a conductive geological feature manifests itself in InfiniTEM data in the form of a complicated, positive-to-negative signature. Such signatures are difficult for the non-specialist to interpret. The goal of this project, therefore, is to develop a data processing technique that will transform the complicated, dipolar InfiniTEM signature of a conductor into a single, simple, consistent peak.
