ECCA
Ecca Geoscience takes its name from the Permian aged Ecca Group in the Karoo Basin, South Africa.
The Ecca Group is a broadly shallowing-upward, marine succession where the distal basin plain deposits of the Vischkuil Formation are overlain by basin-floor fan deposits of the Laingsburg Formation. The overlying submarine slope succession of the Fort Brown Formation is dominated by channel-levee complexes and entrenched slope valleys. Continued progradation and infill of the basin is characterised by the ~400-m-thick lower Waterford Formation, which comprises a mixed river- and wave-influenced deltaic succession.
The shallow marine Waterfords Formation and its temporal and spatial changes in the Laingsburg Basin were the focus of George Jones's PhD thesis which can be found here
