SEISMIC EXPLORATION OF REFRACTRION TYPE

Instrumentation for geognostic investigation

Manufacturer M.A.E. - Advanced Geophysics Instruments

The seismic exploration of refraction type is among the most diffused and used active seismic methods.
This type of survey has the purpose to determine the thickness of the overburdens (aerated) above a rigid sub-layer and reconstruct a seismic stratigraphic sequence in terms of apparent longitudinal speed. If carried out according to more sophisticated calculation methods, it can be used to intercept, measure and characterize geo-structural profiles.
Seismic exploration of refraction type is carried out by placing equidistant geophones in line on the ground, and generating seismic pulses through mechanical “inputs”.
Then the travelling times of the pulses that once penetrated in the ground are refracted nearby the lithological passages at different density, will be measured.
