With the aim to know the paleotopographic pedestal (quartzite) in the ancient sedimentary cover (dolomites and calciaire).IF THE JOINT CROSS SCHEMATIC BASE WHICH WE WANT TO KNOW ITS COVER paleotopographic
Hallo H. Baoutoul,
My approach will be to use seismic refraction. Depending on the depth of investigation, you can use a betsygun as a source to make sure that the energy of the source is large enough and that the frequency content is high enough to compensate for the frequency lost due to the high frequency filtering that the subsurface will have on your seismic waves.
If you can give me more information about the envisaged depth of exploration, I can suggest geophone spacings etc. Please look at my profile and download the paper:" Planning for shallow high resolution seismic surveys".
If you think you can use it, I will mail you an Excell spreadsheet to model the correct frequencies for the depth you are interested in.
Hope this helps.
Kind regards
Stoffel
Either very high resolution seismic reflection survey or the ground penetrating radar should work, depending on the size and depth of the area you are interested in.
Depending upon the depth of occurrence or expected depth of acoustic basement below the seabed (in case of marine environment) or normal ground/earth surface, a high frequency seismic source is a good device. This is true if the acoustic basement is expected to occur at shallow depth.
With variable frequency seismic sources, and appropriate receivers (hydrophone/streamer/geophone array), it is possible to image the paleotopography of the acoustic basement/other subsurface horizons.
depending on in water or on land. you would better give more information about your question.
