Electromagnetic surveys are conducted as a form of geophysical exploration in order to detect non-metallic minerals and valuable minerals. The mining industry uses this surveying method as a means of comparatively lower cost prospecting to acquire useful data for map development. While electromagnetic surveys can be done either by air or on the ground, airborne … Read more

Exploration geophysics is used as a means of uncovering quality data regarding the mineral consistency within certain areas of the Earth’s crust. The information gathered during an exploration aids in the production of geophysical maps, which are utilized by mining companies as part of the prospecting stage for mineral exploration. The process of exploration geophysics … Read more
In terms of conducting geophysical surveys, gamma spectrometry or airborne radiometric surveys can be employed as a means of detecting gamma rays or natural radioactive emanations. This detectable radiation comes from the decaying of some of the natural elements occurring in the Earth. For geological mapping, three elements are most diagnostically useful: potassium, uranium and … Read more
Exploration geophysics is the science of acquiring data regarding the Earth’s properties using above ground survey methods. Electromagnetic surveys are used to assess the varying electric currents conducted between sulphide minerals and barren silicate minerals. Airborne electromagnetic surveys (AEM) offer a fast and cost effective means of acquiring data on electromagnetic currents. Through the use … Read more
Airborne magnetic geophysical surveys or aeromagnetic surveys are one of the most commonly employed geophysical survey methods being practiced today. Aeromagnetic surveys are considered a primary and essential survey technology and are typically flown in conjunction with other survey technologies. An airborne magnetic survey is able to measure the earth’s magnetic fields from the air. … Read more
Airborne geophysical surveys and magnetic data acquisition are common practices that benefit the mining industry and a wide range of exploration professionals. Airborne geophysics provides a broad overview of the geology of a particular area, as well as measure the fluctuating magnetic signatures found in the Earth’s crust that may be indicative of mineral concentrations. … Read more
The acquisition of Airborne magnetic data is the first step in the exploration process, providing geologists with detailed mapping of magnetic field and anomalies. The magnetic data is then interpreted by Geophysical consultants to further pinpoint areas of interest to continue the exploration process. Aeromagnetic surveys acquire the data necessary to create geophysical maps, and … Read more
In the past several decades, airborne magnetic surveys have become a common means of acquiring data required for mineral and hydrocarbon exploration. The information uncovered during a magnetic survey is often the first phase of an exploration program to detect valuable minable magnetic ores such as kimberlites, chrome, and magnetic iron ores, as well as … Read more
