Zusammenfassung
Das Becken von Mexiko befindet sich im Zentrum des Transmexikanischen Vulkangürtels, einer Ost-West-Struktur, die den nordamerikanischen Kontinent entlang des 19. Breitengrades durchschneidet.
Paläomagnetische Messungen legen die Vermutung nahe, daß 2 (Guadalupe- und Chichinautzin-Gruppe) der 7 vulkanischen Phasen, die das Becken formten, von wahrscheinlich kurzer Dauer waren. Die Chichinautzin-Gruppe, die das Becken im Süden abschnürte, muß sich grundsätzlich in den letzten 700 000 Jahren gebildet haben.
Die vulkanische Tätigkeit, die im Oligozän begann und sich kontinuierlich bis in dic heutige Zeit fortsetzte, förderte nachweislich im wesentlichen andesitische Produkte.
Abstract
The basin of Mexico lies in the center of the Trans-Mexican Volcanic Belt, an east-west structure which dissects the North American Continent along the 19th parallel. Paleomagnetic measurements suggest that two of the seven eruptive phases —Guadalupe Group and Chichinautzin Group — that formed the basin, probably were of short duration; the Chichinautzin Group, which finally closed the basin to the south, must have been formed principally in the last 700,000 years.
The volcanic activity which began in Oligocene time and has continued until the present, has been proved to be essentially andesitic in composition.
Résumé
Le bassin de Mexico se trouve au centre de la ceinture volcanique de Mexico, une structure est-ouest qui recoupe le continent nord-Americain près du 19e parallèle. Les mesures paléomagnétiques conduisent à supposer que deux des sept phases d'activités volcaniques, celles de la Guadaloupe et du Chichinautzin, étaient courtes. Les roches du Groupe de Chichinautzin, fermant le bassin au sud, ont été formées pendant les derniers 700,000 ans.
L'activité volcanique, qui a débuté à l'Oligocène et se continue encore actuellement a une charactère essentiellement andésitique.
Краткое содержание
Мексиканский бассей н находится в центре трансмексиканского вулканического пояса — некой структу ры, которая пересекае т северо-американский материк
вдоль 19-й параллели с во стока на запад. Палеомагнитные изме рения разрешают пола гать, что две из семи вулканически х фаз, именно группа Guadalupe и Chichinautzin, образовавших этот бассейн, повсей вероя тности, были очень непродолжттельными. Группа Chichinautzin, продукты которой сос тавляют границу басс ейна на юге, появилась в последние 700000 лет.
Вулканическая деяте льность, начавшаяся в олигоцене и продолжающаяся непрерывно по сегодн я, подняла главным обр азом андезиты.
