Zusammenfassung
Aus dem Nord-Viktoria-Land, Antarktis, wird eine spätkambrische Turbiditfolge mit ihren sedimentologischen, biologischen und tektonischen Kriterien beschrieben. Ähnliche Sequenzen, die quer durch den ganzen Kontinent im Zuge des Transantarktischen Gebirges vorkommen, werden diskutiert. Die geotektonische Bedeutung dieses Flysch-Gürtels wird analysiert in seiner Beziehung zum ostantarktischen Schild, zum Gondwana Kraton und zu einem Proto-Pazifik.
Abstract
A late Precambrian turbidite succession is described from North Victoria Land, Antarctica, in its sedimentological, biological and tectonic aspects. Similar sequences occurring across the whole continent along the present Transantarctic Mountains are discussed. The geotectonic significance of this flysch belt is analysed in its relation to the East Antarctic Shield, the Gondwana craton and a proto-Pacific.
Résumé
L'auteur décrit, avec ses critères sédimentologiques, biologiques et tectoniques, une série de turbidites du Précambrien supérieur dans le Nord de la Terre Victoria de l'Antarctique. Il discute des séries analogues se présentant dans tout le continent suivant la présente Chaîne transantarctique. Il analyse la signification géotectonique de cette ceinture de flysch dans sa relation avec le bouclier de l'Antarctique oriental, du craton du Gondwana et d'un Proto-Pacifique.
Краткое содержание
Описана свита поздни х докембрийских турб идов, залегающих на севере Земли Виктории, Антар ктида. Их присутствие установлено на основ ании седиментологич еских, тектонических и биол огических критериев, а их распространение прослеживается в раз личных частях матери ка. Анализируют геотект оническое значение этих флишев ых поясов и их связь с восточно-антарктиче ским щитом, с кратоном Гонд ваны и с предшевствен ником Великого океана.
