Contribution to the stratigraphy of the onshore Paraíba Basin, Brazil Anais da ABC (AABC)
Rossetti,Dilce F.; Góes,Ana M.; Bezerra,Francisco H.R.; Valeriano,Márcio M.; Brito-Neves,Benjamim B.; Ochoa,Felipe L..
Several publications have contributed to improve the stratigraphy of the Paraíba Basin in northeastern Brazil. However, the characterization and distribution of sedimentary units in onshore areas of this basin are still incomplete, despite their significance for reconstructing the tectono-sedimentary evolution of the South American passive margin. This work provides new information to differentiate among lithologically similar strata, otherwise entirely unrelated in time. This approach included morphological, sedimentological and stratigraphic descriptions based on surface and sub-surface data integrated with remote sensing, optically stimulated luminescence dating, U+Th/He dating of weathered goethite, and heavy mineral analysis. Based on this study, it...

Ostracoda and foraminifera from Paleocene (Olinda well), Paraíba Basin, Brazilian Northeast Anais da ABC (AABC)
PIOVESAN,ENELISE K.; MELO,ROBBYSON M.; LOPES,FERNANDO M.; FAUTH,GERSON; COSTA,DENIZE S..
ABSTRACT Paleocene ostracods and planktonic foraminifera from the Maria Farinha Formation, Paraíba Basin, are herein presented. Eleven ostracod species were identified in the genera Cytherella Jones, Cytherelloidea Alexander, Eocytheropteron Alexander, Semicytherura Wagner, Paracosta Siddiqui, Buntonia Howe, Soudanella Apostolescu, Leguminocythereis Howe and, probably, Pataviella Liebau. The planktonic foraminifera are represented by the genera Guembelitria Cushman, Parvularugoglobigerina Hofker, Woodringina Loeblich and Tappan, Heterohelix Ehrenberg, Zeauvigerina Finlay, Muricohedbergella Huber and Leckie, and Praemurica Olsson, Hemleben, Berggren and Liu. The ostracods and foraminifera analyzed indicate an inner shelf paleoenvironment for the studied...
