General sediment conditions for both these provinces include Holocene-Pleistocene age silts and clays with intervals of sandy clay or sandy layers related to mass transport deposits (MTDs) from gravity flows. A key difference between the provinces is the potential for older geological units...

... complex shallow sediments. Instantaneous amplitude, phase, and frequency are the most widely used seismic attributes to indicate geological features, but those time-domain data are too limited to define an accurate subsurface model in depth. Therefore, seismic inversion is also required to generate...

Seismic inversion is a method to convert the wave signals from time-to space-domain and derive specific material properties by using iterative numerical modeling. In this paper, we introduce a probabilistic seismic...
