Abstract

Key-words: Clay minerals - Eastern Algarve.


XRD-analyses of pelitic deposits of Upper Triassic to Miocene age
occuring in the eastern Algarve (Portugal), give evidence of the occurrence of detrital clay minerals of continental origin as well as of conspicuous neoformations of marine provenance. The vertical succession of clay-mineral associations indicates the existence of three distinctive evolutionary cycles which are thought to reflect tectonically controlled transgressive-regressive events.
