Types of geophysical survey. There are many methods and types of instruments used in geophysical surveys. Technologies used for geophysical surveys include: Seismic methods, such as reflection seismology, seismic refraction, and seismic tomography.This type of survey is carried out to discover the detailed structure of the rock formations beneath the surface of the Earth.
The instruments used were a 22kHz piezoelectric probe generating a sonic (seismic) pulse, and a receiver of the same frequency. A sparker probe with 100J output operating at about 4kHz was also used, but for demonstration only. The procedure required fluid in the boreholes, a condition which was fulfilled only in the sections below the water table.
A poorly lithified and often glauconite rich sandstone rests upon the Precambrian bedrock. The glauconitic sandstone has been formed in a marine environment with relatively high water levels (Kornfält et al. 1978), and it is overlain by the Cretaceous limestone.Several transgressions and regressions occurred during the late Cretaceous, and the limestone consists to a large degree of carbonate ...
