Upper Miocene planktonic foraminifera from Algarve. Chronostratigraphical implications
Ciências da Terra(UNL) Nº 15, pp. 199-208 New data on the planktonic foraminifera from the Upper Miocene Cacela Formation and Mem Moniz spongoliths are presented. The coiling type of Globorotalia menardii from Cacela and Quelfes and the occurrence at Quelfes of G. miotumida allow correlation with th...
