Amplitude
versus offset is a seismic interpretation technique that analyzes
variations in amplitude as a function of offset, in certain
circumstances, it is an indirect hydrocarbon indicator |

In
reference to hydrocarbon traps, one typified by alterations
of the composition (such as permeability) of the natural layering
of the strata |

current (large mass of sediment, such as from rapid erosion
from a canyon or shelf collapse) flowing down a continental
shelf |
