The drift of the Indian subcontinent; an interpretation of recent palaeomagnetic data

  • C. T. Klootwijk

Abstract

The Precambrian and Phanerozoic drift of the Indian subcontinent is discussed on the hand of available palaeomagnetic data.

Hard secondary magnetization components of Early Tertiary Deccan Trap origin were found in a number of red beds studied. Incompatabilities in some previously published red beds data of mainly Early Gondwana age are presumably due to incompletely cleaned results. A modified apparent polar wander curve is proposed after rejecting certain data on the grounds, that they reflect a later Deccan Trap remagnetization.

The spatial and temporal relations between the Early Cretaceous Rajmahal Trap- and the Early Tertiary Deccan Trap effusions does not accord with a mantle fixed hot spot model. The Indian palaeomagnetic data when compared with data from the other Gondwanaland continents favour the hypothesis of an early fragmentational movement of Gondwanaland before Penno-Triassic times. Implications of available palaeomagnetic data on the convergence of India and Asia are discussed in relation to some recent plate tectonic models.

Zusammenfassung

Die präkambrische und phanerozoische Drift des Subkontinentes Indien wird anhand bisheriger paläomagnetischer Daten diskutiert. Harte sekundäre Remanenzkomponenten von frühtertiärer Deccan-Trap-Herkunft wurden in einer Anzahl der untersuchten „red beds“ festgestellt. Unvereinbarkeiten in bisher publizierten „red bed“-Daten von meist Frühgondwana-Alter sind anscheinend die Folge störend überlagernder und nur zum Teil durch die Entmagnetisierung beseitigter sekundärer Remanenzkomponenten. Eine modifizierte Polwanderungskurve wird vorgeschlagen nach Ausschluß bestimmter Daten wegen nicht völlig eliminierter sekundärer Deccan-Trap-Remanenzkomponenten.

Die räumliche und zeitliche Beziehung zwischen den frühkretazischen Rajmahal-Trap- und den frühtertiären Deccan-Trap-Effusionen stimmt nicht überein mit den mantelfixierten „hot spot“-Modellen. Ein Vergleich der paläomagnetischen Daten Indiens mit Daten der anderen Gondwana-Kontinente stützt die Hypothese einer fragmentierenden Bewegung Gondwanas vor der Permotrias. Folgerungen der bisherigen paläomagnetischen Daten für die Konvergenz von Indien und Asien in Beziehung zu rezenten plattentektonischen Modellen werden diskutiert.

Résumé

La dérive précambrienne et phanérozoique du subcontinent indien est discutée à partir des données paléomagnétiques connues aujourd'hui. Des composantes rémanentes secondaires dures, issues de l'activité volcanique du Deccan Traps au début du Tertiaire, ont été identifiées dans des couches rouges.

Des contradictions entre quelques données paléomagnétiques, notamment des couches rouges permiennes et triassiques, sont probablement dues à des données issues d'une désaimantation insuffisante. Il a été proposé une courbe des pôles paléomagnétiques modifiée, après exclusion de certaines données d'où l'influence de cette aimantation sécondaire du Deccan Traps n'a pas été complètement éliminée.

Les rélations dans le temps et dans l'espace entre les effusions des Rajmahal Traps (crétacé inférieur) et des Deccan Traps (début du tertiare) ne concordent pas avec le modèle d'un point chaud fixé dans le manteau. Les données paléomagnétiques Indiennes, comparées avec les données des autres continents gondwaniens, viennent à l'appui de l'hypothèse d'une ancienne phase de fragmentation du Gondwana avant l'époque permotriassique. Certaines implications des données paléomagnétiques disponibles sur le rapprochement de l'Inde et de l'Asie sont actuellement discutées, car elles ne semblent pas en accord avec de nouveaux modèles récemment présentés sur la tectonique des plaques intéressant cette partie du globe.

Краткое содержание

На основании имеющих ся палеомагнитных да нных обсуждается докембр ийский и фанерозойский дрей ф субконтинента Инди и. Твердые вторичные остаточные компонен ты раннетретичного Декан-Трап-происхожд ения установлены в ряде ис следованных «красны х породах».

Все опубликования об этих породах, главн ым образом раннегодв анского возраста, довольно противоречивы. Это св язано с тем, что одна ча сть их осталась перекрытой, а другая — в результат е вторичных процессо в — потеряла остаточный магнетизм. После отбр оса некоторых данных, полученных на образцах, не потерявших полность ю остаточный магнети зм, предложили улучшенн ую кривую смещения полю са. Пространственные и в ременные взаимоотно шения между реннемеловыми эффузиями Rajmahal-Trap и раннет ретичными эффузивми Deccan-Trap не совпадают с моделями «горячих точек», фикс ированными мантией Земли. Сравнение палеомагн итных данных Индии с д атами других материков Год ваны подтверждает гипоте зу о фрагментаром дви жении Годваны в период перм-триас. Рассматри ваются вытекающие из полученных палеомагнитных данных выводы о конве ргенции Индии и Азии в свете современной модели тектоники плит.
