Abstract
Early Carboniferous palynological assemblages from the SM-4 well located in the Llanos Orientales Basin constitute the only definitively geological evidence of Carboniferous strata in this Basin. Stratigraphically significant species include: Anapiculatisporites concinnus, Apiculiretusispora mutiseta, Grandispora spiculifera, Indotriradites dolianitii morphon, Spelaeotriletes pretiosus and Prolycospora rugulosa. The presence of scarce acritarchs indicates a shallow marine environment. A Tournaisian age, probably reaching the Viséan, is proposed for the interval 2010-2340 ft based on the presence of distinctive spore species with previous records in the Viséan and Tournaisian of Western Europe and Western Gondwana. This report increases the knowledge about the distribution and composition of the Early Carboniferous palynological assemblages in Northern Gondwana.
