Exploration Geophysics


Introduction

Airborne and surface geophysics methods are utilised in various geological terrains around the world including greenstones for delineation of favourable target areas for follow-up drilling. A comprehensive data acquisition,. processing and interpretation service is offered. We attach significant importance to in-situ data processing, client involvement during the field phase to ensure that all needs are fully met and a comprehensive geological interpretation of the geophysical results. This may entail integration of geochemical, geological and remote sensing datasets to produce optimised favourability maps.

Techniques

AIRBORNE geophysical methods used include; gradient magnetometry, VLF-EM and HLEM, and multispectral radiometrics. SURFACE methods include gradient magnetometry, gravimetry, induced polarisation, electromagnetic conductivity profiling / sounding and imaging (including MT, CSAMT), 2D resistivity imaging, resistivity sounding, electrokinetic sounding, self potential, and seismic refraction/reflection. BOREHOLE geophysical methods used include; crosshole seismics, seismic tomography, and wireline logging.
