Permian palynostratigraphy of the Claromecó Basin, Argentina

Alcheringa: An Australasian Journal of Palaeontology, 2014
The first palynozonation for Permian strata of the Claromeco Basin (Argentina) is formally proposed, based on palynological assemblages recovered from the UTAL.CMM1 La Estrella.x-1 and UTAL.CMM1 Cruz de Sur.x-1 boreholes, drilled on the Argentinian Continental Platform and correlation with established zones from neighbouring basins.
