Ecca Group
The Ecca Group is the second of the main subdivisions of the Karoo Supergroup of geological strata in southern Africa. It mainly follows conformably after the Dwyka Group in some sections, but in some localities overlying unconformably over much older basement rocks. It underlies the Beaufort Group in all known outcrops and exposures. Based on stratigraphic position, lithostratigraphic correlation, palynological analyses, and other means of geological dating, the Ecca Group ranges between Early to earliest Middle Permian (Asselian - Roadian) in age. Background During the time of the deposition of the Ecca Group, the depositional environment, with some exceptions, was predominantly marine. The Ecca sea was vast but shallow, reaching only around 500 m at its deepest in its west/northwestern and southern facies where the Tanqua and Laingsburg Depocenters are situated respectively. The marine environment ranged from deep pelagic, submarine fan systems in the lower deposits whi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
