IP/Resistivity
IP/RESISTIVITY Fender Geophysics’ key strength is our experience in running numerous styles of Induced Polarisation (IP) in a wide range of environments such as the remote parts of Australia, Peru and Russia, as well as densely populated areas of NSW. We have gained a...
Ground Magnetics
Ground Magnetics Fender Geophysics has years of experience applying ground magnetic surveys to a range of projects in varying environments from large mineral exploration surveys to the detection of buried metal objects such as steel drums and tanks. Magnetic surveys...
Gravity
GRAVITY Measurements of gravity provide information about densities of rocks in the subsurface by making precise measurements of the earth’s gravity field and how it changes spatially. The gravity method is relatively quick, non-invasive and cheap, and can be used...
Magnetotellurics
Magnetotelluric (MT) methods are a passive geophysical method that infer the Earth’s subsurface resistivity though measuring naturally occurring geomagnetic and geoelectrical fields at the Earth’s surface. These naturally occurring fields occur over a wide band of frequencies. Low frequencies correspond to locations deep in the crust, while high frequencies correspond to shallow depths. MT surveys focus on depth ranges from 100-10,000m and therefore have a much greater depth of penetration than other electrical or electromagnetic methods. MT measurements allow geologists to determine resistivity as a function of depth. The electrical resistivity of rocks and soils is a function of mineralogy, porosity, permeability, temperature and fluid composition.
