Dome-Growth Stages

Abstract

As a salt structure evolves, it passes through three stages of growth, known as the pillow stage, the diapir stage, and the postdiapir stage. The model shown in figures 1 and 2 assumes that all thickness variations in strata are primary and caused by syndepositional rise or fall of the sedimentation surface because of salt flow beneath. Evidence suggests that once initiated, the crest of a salt diapir stays more or less at a constant shallow depth while its base and the surrounding strata sink as the basin floor subsides, a process known as downbuilding.
