- Middle-Upper Jurassic palynology of the Sagres region and the Carrapateira Outlier, southern PortugalPublication . Borges, Marisa; Fernandes, Paulo; Pereira, Zélia; Riding, James B.The palynology of the Middle-Upper Jurassic fill of the Sagres region (Algarve Basin) and the Carrapateira outlier, southern Portugal was investigated. Samples were collected from Mareta beach, Cilheta beach and the Carrapateira outlier. Dinoflagellate cysts are confined to the Upper Bajocian to Upper Callovian sedimentary rocks exposed at Mareta and Cilheta beaches and the Lower Kimmeridgian strata of the Carrapateira outlier. The palynostratigraphical study of the Jurassic successions has yielded new biostratigraphical data based on dinoflagellate cysts and miospores. The results confirm, and in some cases refine, the existing macrofaunal age determinations of these successions.
- A re-assessment of the organic maturation and palynostratigraphy of the wells Ruivo-1 and Corvina, offshore Algarve Basin PortugalPublication . Fernandes, Paulo; Borges, Marisa; Rodrigues, B.; Matos, V.The Algarve Basin is the southernmost geological province of portugal. The nowledge of its offshore geology is limited to a few hydrocarbon exploration wells and seismic profiles. Two of these wells, Ruivo-1 and Corvina, were studied in order to assess its organic maturation levels and age using the biostratigraphy of dinoflagellate cysts. The well Ruivo-1 intercepted a thick Callovian succession whereas the well Corvina intercepted a thick Oxfordian succession. Both Jurassic successions are within the oil-window.
