Example of Application of Geophysical Techniques in Determining Geological Environment of a Coal Deposit

摘要

Geophysical seismic and gravity techniques have been of definite and tangible use in prospecting for Gondwana coal deposits in the Bogra-Rajshahi districts of East Pakistan. The geophysical inferences confirmed by drill holes have established that the distribution and attitude of the coal deposits are controlled by the configuration of the basement. By studying the environmental factors of the coal deposit it has been possible to delineate the limits of deposition and indicate the shallowest possible depth of a workable coal deposit in the Bogra-Rajshahi area. The results aptly and amply demonstrate the application of geophysical techniques in determining the subsurface geological environment of a mineral deposit.
