Abstract

The Baton Rouge Fault System (BRFS) is a system of deep-seated, east-trending normal faults. Analysis of a 2-D industry seismic dataset in Lake Pontchartrain and two, 3-D datasets in Lake Borgne, revealed three faults that may show lateral continuity beneath the East Orleans Land Bridge (EOLB). Biostratigraphy from 33 oil/gas industry well logs were used for correlation with deep seismic data. BasinMod was used to generate a burial history of the Cenozoic strata. Cross sections of 22 collected vibracores with 500 yr BP interval isochron estimations, calculated from 17 vibracore samples of radiocarbon dated (C14) relict marsh organics and Rangia cuneata shells, show fault displacement in Holocene stratigraphy. A grid of high-resolution, Chirp seismic data collected shows visible offset of strata during the Late Pleistocene and Holocene. Aerial imagery and Lidar datasets show possible scarps and other surface expressions along the projected surface traces of the BRFS on the EOLB.
