Radiometric Surveys detect and map gamma rays, and can be performed on the ground, in the air, or in a borehole. Airborne gamma-ray spectrometry or radiometric surveying for mineral exploration measures the gamma-rays that are emitted from naturally occurring radioactive isotopes that are found in rocks and soils near the surface. The most abundant of these … Read more
Geophysical surveying is a technique of the mining industry which uses a specialized instruments to measure the physical properties of rocks and soil in the surface and subsurface. The goal of geophysical surveying is to detect and/or predict the presence and position of elements and minerals, ground water, oil and gas and other components of … Read more
Geophysical Survey Increases Geophysical survey companies are experiencing significant growth due to increases in the number of mineral and oil exploration projects worldwide. Declines in reserves are directly tied to an increase in funding for exploration activities. Geophysical surveys are an essential part of these exploration processes and are imperative to locating mineral or hydrocarbon … Read more
A Growing Industry The practice of geophysical surveying is growing in popularity and acceptance due to breakthroughs in the technology. Geophysical surveys are important because they provide the ability to accurately map a survey area rapidly and economically. There are many innovative and exciting advances in the industry of geophysical surveys that will alter the … Read more
Geophysical exploration is a means of sourcing out high concentrations of various minerals and commodities under the Earth’s surface by employing surveying methods, such as electromagnetic surveys and magnetic surveys. Geophysical exploration can be conducted on the ground or by air and can detect a variety of different magnetic minable ores such as kimberlites and … Read more
A qualified geophysical company is capable of providing a wide range of geophysical surveying services, though typically specialize in either ground or airborne acquisition. The capabilities of a geophysical company are contingent upon their years of survey experience within the field of geophysical exploration as well as their dedication to quality QA/QC and good field … Read more
Quality, experienced Geophysicists are integral to overseeing the proper execution of all stages of the the acquisition process. Starting with initial survey design and an extensive review of the client’s survey targets and goals, Terraquest incorporates an experienced Geophysicist from the start of the planning process to provide input into extensive survey planning including, There … Read more
Even though airborne surveys are a relatively low cost and efficient method of exploration, each survey must be as economically viable as possible in the grassroots stage of exploration. Therefore it is extremely important that your airborne survey is thoroughly planned and executed according to the predetermined survey plan. Integral to the planning process are … Read more
Airborne Electromagnetic geophysical surveys measuring the electrical resistivity of the earth are conducted from the air using towed EM arrays or EM loops. Airborne EM typically use a transmitter that carries a current that varies in magnitude as a function of time to measure electromagnetic conductors. In Time domain EM systems, the current is turned … Read more
