A Palynological And Sequence Stratigraphic Study Of Santonian - Maastrichtan Strata From The Upper Magdalena Basin, Sandra Garzon

LSU Master's Theses

This manuscript presents a biostratigraphic and sequence stratigraphic interpretation of palynological data from two outcrop sections on the NE flank of the Upper Magdalena Valley (UMV) basin comprising the Santonian to Lower Maastrichtian interval. The objectives of this study where: a) to characterize the lithologically similar Lower Lidita, Upper Lidita, and El Cobre, Buscavidas formations and b) to provide a better understanding of important correlation horizons in the northeastern part of the UMV basin and to confirm the age assignment of stratal units. A cyclic pattern of palynomorph distribution was recognized in both sections and tied to the different stages …
