This document discusses gravity induced structures in sedimentary basins, specifically diapirs, diapirism, and growth structures. It defines diapirs as intrusions of sedimentary rocks like salt or mudstone into overlying sequences. Diapirism is a dynamic process that occurs under gravity as sediments accumulate, deforming the strata. Growth structures include growth faults, which are faults with thicker sequences on the downthrown side that increase in throw with depth, and listric faults, which are curved normal faults concave upward.
