Why Use Aeromagnetic Surveys? Aeromagnetic surveys are an efficient geophysical prospecting tool for many mineral and petroleum exploration companies and government agencies. A fixed-wing airplane or helicopter is extensively modified to be magnetically quiet and equipped with wingtip pods, a tail stinger, or a towed bird to house magnetometers for acquiring magnetic data. This type … Read more
Airborne magnetic surveys are an important geophysical prospecting tool for many applications. These surveys make it possible to gather detailed information about the presence of various magnetic and non-magnetic materials in the Earth’s crust over large geographical areas. This type of survey is cost-effective, safe and time efficient because of the large areas of land … Read more
Magnetic surveying is a geophysical method used in the mining industry to locate, calculate and determine quantities of minerals beneath the ground. It monitors spatial variations in the Earth’s magnetic field, which allows specialists to detect and map artifacts, features and various other formations beneath the Earth’s crust. These formations are often large deposits of … Read more
The Demand for Geophysical Surveys; Greater global demand for minerals is leading to an increased demand for mineral exploration and in turn geophysical surveying. Airborne geophysical surveying, in particular magnetics and radiometrics have become leading techniques to initiate the mineral exploration process, by economically and efficiently acquiring data from the air using small fixed wing … Read more
A mineral exploration is conducted in several stages, and the prospecting stage is arguably one of the most important. Mineral prospecting can be done in various different ways and geophysical surveys are enabling mining companies to acquire highly accurate results with regards to the mineral concentrations in the Earth’s crust. There are two specific types … Read more
Mining companies in the prospecting stage source out airborne geophysical companies that specialize in conducting highly precise surveys and employ reliable data acquisition services, as well as precise interpretation capabilities. The success of a geophysical survey is dependent not only upon the survey itself, but the ability to interpret the data obtained accurately and apply … Read more
Airborne geophysical data can be used indirectly to map some geological features in detail, including contacts, faults, shear zones, folds, alteration zones and other structures. To obtain this data, survey areas are systematically traversed by fixed wing or rotary wing aircraft carrying geophysical equipment along parallel flight lines. The traverse lines are oriented to intersect … Read more
There are a variety of geophysical survey methods that are used both in mineral prospecting or regional mapping. Using either ground or airborne techniques, geophysical companies employ the use of magnetic, radiometric and electromagnetic equipment to detect concentrations of minerals in the Earth’s crust. Magnetic Surveys: The most commonly used geophysical survey method is the … Read more
