Die Röntgenanaly se der Tonfraktion des Ober-Aptien aus dem Azarcq Becken zeigt die Anwesenheit von Illit, Mischmineralien (Illit-Montmorillonit) , Allevardit, Corrensit und Chlorit. Nach Untersuchung der Verteilung der Mineralien in diesem Becken, kommen die Verfasser zum Schluss dass eine Umbildung durch «Agradierung » der verwitterten Mineralien in einem karbonathaltigen chemischen Milieu.X ray diffraction analysis of the clay-fraction separated from rocks of the upper Aptian in the Arzacq Basin shows the presence of illite, irregular mixed-layered illite-montmorillonite, allevardite, corrensite and chlorite. After studying how the different minerals are distributed over the basin, we conclude upon a transformation through agradation of ...
