OCORRÊNCIA DE PALINOMORFOS EM SEDIMENTOS PALEOZÓICOS DA BACIA DE JATOBÁ (PERNAMBUCO)

Resumo

The palynological analysis of Paleozoic sediments of 2-IMst-l-PE (Ibimirim-Pernambuco, Jatobá Basin) well, yielded microfossils such Ancyrospora cf. ancyrea, Hystricosporites corystus, Maranhites brasiliensis, Reticulatisporites spp., Hymenozonotriletes lepidophytus, Knoxisporites spp and Tholisporites sp. This association characterize the Upper Devonian (Strunian) and Lower Carboniferous (Tournaisian/Visean) to the interval studied. On the Devonian sediments of Ibimirim well, were found a great amount of the genus Maranhites and Tasmanites which are normally associated with reducing conditions and sediments rich on radioative elements like uranium and radium. The Devonian microfossils forms characterize marine conditions; on the Carboniferous section there are not evidences of the depositional environment. The paper presents illustrations of the sporomorphs acompanied by correlation with Carboniferous and Devonian sediments from the Mac Mahon Basin (Algerian Sahara) and comparison with the Devonian from the Paraná Basin.
