http://www.coastalwiki.org/wiki/Closure_depth WebThe computations needed in order to create a sediment thickness from a velocity profile are quite basic, and can be derived from the fact that depth equals time multiplied by velocity. The vital step in depth conversion is determining the correct interval velocities, which is done when generating the velocity profile. senior thesis animationWebFigure 5.4. 1: Horizontal strata in southern Utah. The most basic sedimentary structure is bedding planes, the planes that separate the layers or strata in sedimentary and some volcanic rocks. Visible in exposed outcroppings, each bedding plane indicates a change in sediment deposition conditions. This change may be subtle. senior things to do
