Zusammenfassung

Die tonalitische Magmenfolge des Archäikum wird durch hohe Al2O3- und Na2O-Gehalte gekennzeichnet. Tertiäraltrige Tonalite mit ähnlicher Hauptelement-Zusammensetzung entstanden in Subduktionszonen. Deshalb wird vorgeschlagen, daß die archäischen Tonalite im Zusammenhang mit Subduktionszonen entstanden, wobei das primäre Magma der Folge dioritischer Zusammensetzung war. Das primäre Magma entstand unter einem Druck von etwa 15 kbar; in jüngster Zeit entsteht aber Andesit bei etwa 30 kbar. Die höhere Entstehungsrate im Archäikum wird, so wie auch die verhältnismäßig geringe Entstehungstiefe, zu den etwas höheren Manteltemperaturen im Archäikum in Beziehung gesetzt.

Abstract

The Archean tonalitic magma series is characterized by a high Al2O3 and Na2O content. Tertiary tonalites with similar major element composition have been generated in subduction zones. It is therefore suggested that the Archean tonalites was generated in relation to subduction zones, the primary magma of the series being of dioritic composition. The generation of the primary magma occurred at about 15 kbar, while the recent generation of andesite occur at about 30 kbar. The higher frequency of generation in the Archean, and the relatively small depth of geneeration is related to the slightly higher temperatures of the mantle in the Archean.

Résumé

La série des magmas tonalitiques de l'Archéen est caractérisée par une haute teneur en Al2O3. Les tonalites tertiaires, de même composition quant aux éléments majeurs, ont été engendrées dans des zones de subduction. C'est pourquoi il est suggéré que les tonalites archéennes aient été engendrées en relation avec des zones de subduction, le magma primaire de la série étant de composition dioritique. La genèse du magma primaire se fit sous environ 15 kbar, tandis que la genèse récente des andésites se fait à 30 kbar. La fréquence élevée de la formation dans l'Archéen et la profondeur relativement faible de cette formation est en liaison avec les températures légèrement plus élevées du manteau dans l'Archéen.

Краткое содержание

Тоналитные свиты маг мы архея характеризу ются высоким содержанием окисей алюминия и нат рия. Тоналиты третичн ого возраста, по химическ ому составу основных эле ментов сходные с выше названными, возникло, вероятно, в зоне субдукции. Поэт ому высказыввется предположение, что ар хейские тоналиты тоже образо вались в зонах субдук ции, причем первичная магма могла иметь диоритны й состав. Первичная ма гма могла возникнуть при давле нии в 15 кбар. Более быстрое обазование ее в архее, как и сравнительно небольшую гоубину ее залегания, связывают с более высокой темппратуро й мантии Земли в архее.
