Abstract An outcrop succession of the Challacó Formation preserved on southern flank Huincul Arch, at Quebrada del Sapo locality, Picún Leufú Sub‐basin, Neuquén Basin, Argentina, enabled us to carry out study a palynobiota. Several taxa are documented for first time in Argentina and Jurassic deposits as well strata other regions world. In light these unconventional records, diagnosis two has been extended (i.e. Trachysporites Ovoidites tripartitus ). On basis palynostratigraphic markers...
Palynofacies analysis of surface sediments from the Beagle Channel, Tierra del Fuego, Argentina, was carried out to establish modern analogues for comparison with other Holocene marine records in southern Isla Grande de Fuego. Our results show dominance highly degraded translucent phytoclasts, associated amorphous organic matter (AOM) and palynomorphs, while opaque phytoclasts are poorly represented. The constituents indicate proximity continental source area environments, distances and/or...
There are few recognized examples of fluvial-dominated deltaic systems affected by hyperpycnal discharges. The development predictive models in those essential to understand the distribution sedimentary facies and for determining location main sandy bodies, which constitute potential hidrocarbon reservoirs. In Portada Covunco Sierra de la Vaca Muerta areas (Neuquén, Argentina), Lajas Formation constitutes an excellent example a fluvio-dominated succession consisting prodelta front...
A multidisciplinary analysis of palynofacies in a sequence-stratigraphical framework, TOC (total organic carbon) and TAI (thermal alteration index) analyses, has been applied to outcrop samples the uppermost Los Molles Formation (Middle Jurassic), Neuquén Basin, Argentina, order characterise palaeoenvironmental palaeoclimatic conditions during deposition this unit.Five types (P-1 P-5) have identified are interpreted indicate restricted marine inner neritic environment.In P-1 P-4, environment...
The statistical analysis of published Paleocene–Late Miocene palynological data from Patagonia supports several major stages vegetation. These represent distinctive floral assemblages, both in composition and structure. Detrended correspondence shows that during the Paleocene, southern South America was dominated by Australasian, Neotropical Pantropical phytogeographical elements (Gondwanic paleoflora). climate warm very humid. Early Eocene taxa (Subtropical Gondwanic Paleoflora) a reduced...
This work aims to analyze the paleovegetation, paleoclimates and paleoceanography of Paleogene Río Foyel section (El Group), Ñirihuau Basin, Argentina.It comprises Troncoso, Salto del Macho formations.Sporomorph analysis reflects a regional forest dominated by Nothofagaceae, Myrtaceae, Podocarpaceae Palmae, developed under temperate warm-temperate humid climate.In studied section, relation between terrestrial/marine palynomorphs is considered.In Troncoso Formation, terrigenous dominate over...
PALYNOSTRATIGRAPHY OF SALTO DEL MACHO FORMATION, PALEOGENE THE ÑIRIHUAU BASIN, ARGENTINA. The complete record of the palynomorphs from Salto del Macho Formation (Paleogene) is presented its type locality at Foyel River section, Ñirihuau Basin Andean area, Argentina. Elements continental and marine origin were identified: a total 109 species corresponding to Bryophyta, Lycopodiophyta Polypodiosida spores, Gymnospermophyta Magnoliophyta (Angiospermae) pollen grains, algae organic-walled...
PALYNOLOGICAL STUDY OF SPORES FROM SALTO DEL MACHO FORMATION, PALEOGENE THE ÑIRIHUAU BASIN, ARGENTINA. The first palynological data from the type locality of Salto del Macho Formation, at Río Foyel section, Ñirihuau Basin, Argentina, is here presented. Nineteen taxa trilete and monolete spores Bryophyta Tracheophyta (Lycopsida Polypodiopsida) belonging to following genera were recorded: Anthocerisporis, Azolla, Baculatisporites, Biretisporites, Cingutriletes, Cyatheacidites, Cyathidites,...
Palynological analysis, with emphasis on palynofacial analysis was carried out Holocene marine deposits located the northern coast of Beagle Channel, Argentina.This allowed paleoenvironmental assessments and paleoclimatic inferences.A fossil section from Albufera Lanushuaia (54°52'04.4"S-67°60'44.9"O),located Channel analyzed.The set particulate organic matter indicate proximity area continental input to environments, distances and/or times transport relatively short.The presence pyrite...
