Abstract

Clay mineral and trace element data indicate that sediments in the vicinity of the North Mid-Atlantic Ridge derive from material of both Icelandic and Canadian origin. These sources agree with the marine and atmospheric circulation patterns observed in this area.

Resume

Resume

Les données concernant les minéraux argileux et les éléments traces indiquent que les sédiments situés près de la dorsale médio-atlantique nord dérivent de matériaux à la fois d'origine islandique et canadienne. Ces sources sont en accord avec les réseaux de circulation marine et atmosphérique observés dans cette région.

Kurzreferat

Kurzreferat

Daten über die Tonmineralogie und die Spurenelementgehalte weisen darauf hin, daß die Sedimente in der Nähe des Nördlichen Mittelatlantischen Rückens sowohl aus dem isländischen als auch aus dem kanadischen Raum stammen. Dies stimmt mit den atmosphärischen und marinen Zirkulationen dieses Bereiches überein.

Resumen

Resumen

Los resultados de los análisis de minerales de la arcilla y de elementos trazas en sedimentos cercanos al dorsal centro-atlántico septentrional, indican que estos sedimentos derivan de materiales procedentes de Islandia y Canadá. Este origen está, de acuerdo con los esquemas de circulación marina y atmosférica observados en esta zona.
