Abstract The Rio de la Plata Craton (RPC) comprises extensive Neoproterozoic sedimentary successions cropping out mainly in Uruguay and Argentina. The lithostratigraphy and depositional environments of the Las Ventanas, Piedras de Afilar, Cerro Negro and Balcarce formations, and Mina Verdun, Sierras Bayas and Arroyo del Soldado groups is reviewed and

Marine Jurassic lithostratigraphy of Thailand
Journal of Southeast Asian Earth Sciences, 1996Abstract Marine Jurassic rocks of Thailand are well-exposed in the Mae Sot and Umphang areas and less extensively near Mae Hong Son, Kanchanaburi, Chumphon and Nakhon Si Thammarat, in the north, west, and south respectively. They are generally underlain unconformably by Triassic and overlain by Quaternary strata.

Lithostratigraphie de la grotte Scladina
Bulletin de l'Association française pour l'étude du quaternaire, 1986La Grotte Scladina comporte des sédiments d'une composition très variée. Après l'activité karstique un loess très ancien marque la première pointe froide du Weichsel. II est suivi de quatre niveaux cryoclastiques et des loess hesbayens. Ces couches froides sont séparées par des phases tempérées, représentées par des croûtes stalagmitiques, horizons ...

Lithostratigraphy of the Mesoproterozoic Twakputs Gneiss
South African Journal of Geology, 2021Abstract The Twakputs Gneiss is a garnetiferous, K-feldspar megacrystic, biotite granite-granodiorite orthogneiss. It represents a major unit in the Kakamas Domain of the Mesoproterozoic Namaqua-Natal Metamorphic Province extending about 250 km between Riemvasmaak in South Africa and Grünau in southern Namibia. The Twakputs Gneiss occurs

AAPG Bulletin, 1956
Practical considerations indicate a need for the recognition of three fundamentally differing kinds of lithostratigraphic units: (1) group, formation, member, et cetera, which are traditionally designated on the basis of their position in vertical sequence; (2) lithofacies, which are lateral quantitative variants; and (3) mutually intertongued bodies ...

Lithostratigraphy of the Mesoproterozoic Kliphoek Granite
South African Journal of Geology, 2016The Kliphoek Granite is a mesocratic, porphyritic post-tectonic granite in the western Namaqualand sector of the Mesoproterozoic Namaqua-Natal Belt. It was mapped as one of 26 different types of granite of the Spektakel Suite by Council for Geoscience geologists.

Lithostratigraphy of the Mesoproterozoic Jannelsepan Formation
South African Journal of Geology, 2017The Jannelsepan Formation forms part of the 1.30 to 1.24 Ga Areachap Group. It is a pre-tectonic calc-alkaline volcano-sedimentary unit in the 1.2 to 1.0 Ga Namaqua Sector of the Namaqua-Natal Metamorphic Province. The main rock types are amphibolites with subordinate clinopyroxene or biotite.

Gondwana Lithostratigraphy of Peninsular India
Gondwana Research, 2002Abstract The controversy regarding the stratigraphic interpretation of the Indian Gondwana succession in the Peninsular Basins has continued for more than a century, with the exception of the Damodar and Satpura Basins. While the stratigraphic reconstruction in Damodar and Satpur was based on the order of superposition of strata, elsewhere the ...

Lithostratigraphy of the Mesoproterozoic Wilgenhoutsdrif Group
South African Journal of Geology, 2017The Mesoproterozoic metamorphic formations of the Wilgenhoutsdrif Group underlie a large area around the Orange River east of Upington. The quartzitic Grootdrink Formation occurs at the base of the sequence and contacts with older units are either unconformable or along thrusts.
