Pliocene to Recent infilling and subsidence of intraslope basins offshore Louisiana

Intraslope basins on the lower eastern Louisiana continental slope are modern analogs of large oil- and gas-charged basins infilled on the upper Louisiana slope and buried landward beneath the shelf. High-resolution, gridded multibeam bathymetry and single-channel seismic reflection profiles are used to 1) characterize the morphology and shallow stratigraphy of 46 intraslope basins within the outer slope region; and 2) look for surficial evidence among the basins of slope channelways that fed sediment flows to the Mississippi Fan during the Pliocene-Pleistocene. -from Authors
