dc.description.abstractThe Travis Peak Formation has been stratigraphically divided into five units through well-log correlations. A depositional system tract characterized by fluvial-deltaic-paralic-shelf environments was interpreted based on analyses of sedimentological and stratigraphic data from each unit, along with well-log and core data. During the early development of the Travis Peak Formation, braided streams deposited sediments such as channelbelt, floodplain, and overbank deposits across most of the study area. Towards the downdip regions of the braided streams, deltas extended southward and southeastward over a shallow and stable shelf. As the braided streams migrated and expanded, the location of deltaic deposition moved southward and expanded northeastward. Estuaries formed in areas between the centers of deltaic deposition where sediment supply was relatively low. Seaward of the deltas, shelf sandstones accumulated due to sediment-gravity processes induced by high sediment loads and rapid deposition in the deltas. The late evolution of the Travis Peak Formation is characterized by shoreline transgression and the development of coastal-plain and paralic environments. Fluvial systems transported a sediment load rich in mud and transitioned from sinuous-braided to meandering forms. Channelbelts traversed a coastal plain with extensive floodplains and lakes, feeding small retrogradational deltas. Estuaries grew larger and became prominent coastal features as the coastal plain continued to submerge. With ongoing transgression, marine limestone of the Sligo Formation overlapped the Travis Peak Formation.
