Abstract:
Global changes in sea level, primarily the results of tectonism and glaciation, control deep-sea sedimentation. During periods of low sea level, the frequency of turbidity currents is greatly increased. Episodes of low sea level also cause vigorous contour currents which winnow away the fines of turbidites. In the rock record, the occurrence of most turbidites and winnowed turbidites closely corresponds to global lowstands of paleo-sea level. An important exploration attribute of this model is the possibility of predicting the occurrence of potential deep-sea reservoir facies in frontier areas of exploration. This model may also be useful in resolving the controversy over a shallow-versus deep-water origin for certain Gulf Coast reservoirs.
