Zusammenfassung
Ein Vergleich von absoluten ‚'Argon“-Altersbestimmungen an kristallinen Gesteinen der ‚'Crystalline Nappe“ (Kumar, 1971, unveröffentlichte Doktorarbeit) und der ‚'Root zone“ (Jaspa Granit) führt zu einem wichtigen Ergebnis in bezug auf die Interpretation der Entwicklung der ‚'Crystalline Nappe“ und ihrer Verjüngung.
Abstract
Comparison of “argon” absolute age determinations of crystalline rocks of the “Crystalline Nappe” (Kumar, 1971, unpublished Ph. D. thesis) and of the “root-zone” (Jaspa granite) has led to an important conclusion concerning the interpretation of the development of the “crystalline nappe” and its rejuvenation.
Résumé
La comparaison de déterminations d'âge absolu à l'aide de la méthode « Argon » sur des roches cristallines de la « nappe cristalline » (Kumar, 1971, thèse de doctorat nonpubliée) et de la « Root zone » (granite de Jaspa) a fourni un résultat important relatif à l'interprétation du développement de la « nappe cristalline » et de son rajeunissement.
Краткое содержание
Сравнение абсолютно го возраста кристалл иновых пород „кристаллинового покрова“ (Kumar, 1971, неопублик ованая диссертация) и ноны „корней“ (гранит Jaspa) по аргоновом у методу дало новые ас пекты для интерпретуции развития этого крист аллинового покрова и его „омоложения“.
