Quantitative interpretation of VLF anomalies under difficult geological conditions can be conducted with modified methods, developed in magnetic prospecting. Over complex geological sections. Abstract (summary): An airborne electromagnetic (AEM) prospecting system is used as a very rapid means of economically searching large geologically potential areas for sulphide ore bodies within the top few hundred feet of the earth's surface. This is possible because massive sulphide ores are usually much more electrically conductive than most host rocks.

Electromagnetic methods Introduction The electromagnetic techniques have the broadest range of different instrumental systems. They can be classified as either time domain (TEM) of frequency domain (FEM) systems. FEM: use one or more frequencies TEM: Measurements as a function of time. Electromagnetic method Electromagnetic (EM) surveying methods make use of the response of the ground to the propagation of electromagnetic field. This response vary according to the conductivity of the ground (in S/m). • Primary EM fields are generated using a alternating current in a loop wire (coil) or a natural EM sourceFile Size: 2MB.

  The paper describes equipment designed to study the effect of a conducting hostrock/overburden on the electromagnetic anomaly of sulphide ore bodies embedded therein. The model was constructed strictly according to the theory of electromagnetic similitude so as to constitute a direct reading reproduction of the field vectors. The experiments were conducted at a fixed, crystal Cited by: 1. Gravity measurements define anomalous density within the Earth; in most cases, ground-based gravimeters are used to precisely measure variations in the gravity field at different points. Gravity anomalies are computed by subtracting a regional field from the measured field, which result in gravitational anomalies that correlate with source body.
