Typical Seismic Velocities for Earth materials

Post by Mohamed »

I was wondering what the typical seismic velocities of the following earth materials would be based on the model shown below (created with MS Paint :oops: ). I know that the typical seismic velocity of the water is somewhere between 1400-1500 m/s, but how about the typical seismic velocities of the unconsolidated sediments and the basement underneath them? I have no information about lithology and depth.

The seismic velocities of earth crustal bedrocks (as the "basement in your model?) should be around 6 to 8 km/s. The thickness (mainly thin such as less than several hundreds meters, but up to 10km?) and the seismic velocity (mainly 2 to 4 km/s?) of the sediment vary a lot depending on the locations. BTW, the image is not bad.

Thanks a ton, gmowoe. That helps.
