Petrographic and SEM data indicate that the veins are fracture filling structures, with three types of textures:1) Granular aggregates of calcite (GA); 2) Elongated granular aggregates of calcite (EGA); and 3) Fibrous aggregates of calcite and dolomite (FA). The textural relationship suggests that GA must have been formed in an environment of widespread extension of the basin, while EGA and FA must have been formed in a compressive environment. The geochemical analyses of REE carried out in the dominant fill of the veins (GA) indicate that these fillings must have been formed in a closed system (intraformational fluid movement) for the drilling well Alfa-1, while in the drilling wells Alfa-2 and Alfa 3, these fills (GA) must have been formed in a characteristic environment of open system (transformational fluid movement).

  • Paleontology and Sedimentology of Middle Eocene Rocks in Lago Argentino Area, Santa Cruz Province, Argentina
    AMEGHINIANA (Rev. Asoc. Paleontol. Argent.) - 46 (1): 27-47. Buenos Aires, 30-04-2009 ISSN 0002-7014 Paleontology and sedimentology of Middle Eocene rocks in Lago Argentino area, Santa Cruz Province, Argentina Silvio CASADÍO1,2, Miguel GRIFFIN1,2, Sergio MARENSSI3,2, Laura NET4, Ana PARRAS1,2, Martín RODRÍGUEZ RAISING5,2 and Sergio SANTILLANA3 Abstract. Sedimentological and paleontological study of the Man Aike Formation at the Estancia 25 de Mayo, SW of Santa Cruz Province, Argentina, represents the evolution of an incised valley from fluvial to marine environment during the late middle Eocene. At the base of the unit there is an unconformity that corresponds to fluvial channels which cut down into the underlying Maastrichtian sandstones of the Calafate Formation. The fauna of invertebrates (mostly molluscs) illustrated herein was collected from shell beds interpreted as tidal ravinement surfaces. The fauna includes terebratulid brachiopods, bivalves of the families Malletiidae, Mytilidae, Pinnidae, Ostreidae, Pectinidae, Carditidae, Crassatellidae, Lahillidae, Mactridae, Veneridae, and Hiatellidae, and gastropods of the families Trochidae and Calyptraeidae, and a member of Archaeogastropoda of uncertain affinities. The similarities of this fauna with that recorded in the Upper Member of the Río Turbio Formation, together with 87Sr/86Sr ages, sug- gest a late Middle Eocene age for the Man Aike Formation. Resumen. PALEONTOLOGÍA Y SEDIMENTOLOGÍA DE LAS ROCAS DEL EOCENO MEDIO EXPUESTAS EN EL ÁREA DE LAGO ARGENTINO, PROVINCIA DE SANTA CRUZ, ARGENTINA. Los estudios sedimentológicos y paleontológicos real- izados en rocas asignadas a la Formación Man Aike, expuestas en la estancia 25 de Mayo, al sur de Calafate, provincia de Santa Cruz, Argentina, sugieren que esta unidad representa la evolución de un valle inciso desde ambientes fluviales a marinos durante el Eoceno medio tardío.

ABSTRACT This study �ocuses on the lower Aptian desmoceratid �auna o� Oliete sub-basin (Teruel province). The systematic revision o� these biostratigraphy well constrained ammonites, allowed us to work on two issues. On the fist place, we improved the systematic and taxonomic knowledge about Pseudosaynella raresulcata (d’Orbigny, 1841), Pseudosaynella bicurvata (Michelin, 1838) and Pseudohaploceras liptoviensis (Zeuschner, 1856) whose definitions, previous to this study, were based on scarce material and �ew studies on their ontoge- netic variation. On a second place, we constrained their stratigraphical ranges, especially �or the Pseudosaynella species, and their correlation with the lower Aptian standard ammonite Mediterranean zonation. Keywords: lower Aptian, ammonoids, systematics, biostratigraphy, Oliete sub-basin, Iberian Chain, Te- ruel, Spain.

  • The Barremian Heteromorph Ammonite Dissimilites from Northern Italy: Taxonomy and Evolutionary Implications
    The Barremian heteromorph ammonite Dissimilites from northern Italy: Taxonomy and evolutionary implications ALEXANDER LUKENEDER and SUSANNE LUKENEDER Lukeneder, A. and Lukeneder, S. 2014. The Barremian heteromorph ammonite Dissimilites from northern Italy: Taxon- omy and evolutionary implications. Acta Palaeontologica Polonica 59 (3): 663–680. A new acrioceratid ammonite, Dissimilites intermedius sp. nov., from the Barremian (Lower Cretaceous) of the Puez area (Dolomites, northern Italy) is described. Dissimilites intermedius sp. nov. is an intermediate form between D. dissimilis and D. trinodosum. The new species combines the ribbing style of D. dissimilis (bifurcating with intercalating single ribs) with the tuberculation style of D. trinodosum (trituberculation on entire shell). The shallow-helical spire, entirely comprising single ribs intercalated by trituberculated main ribs, is similar to the one of the assumed ancestor Acrioceras, whereas the increasing curvation of the younger forms resembles similar patterns observed in the descendant Toxoc- eratoides. These characters support the hypothesis of a direct evolutionary lineage from Acrioceras via Dissimilites to Toxoceratoides. D. intermedius sp. nov. ranges from the upper Lower Barremian (Moutoniceras moutonianum Zone) to the lower Upper Barremian (Toxancyloceras vandenheckii Zone). The new species allows to better understand the evolu- tion of the genus Dissimilites. The genus appears within the Nicklesia pulchella Zone represented by D. duboise, which most likely evolved into D. dissimilis. In the Kotetishvilia compressissima Zone, two morphological forms developed: smaller forms very similar to Acrioceras and forms with very long shaft and juvenile spire like in D. intermedius sp. nov. The latter most likely gave rise to D. subalternatus and D. trinodosum in the M.

EMIG Abstract: The first descriptions of Lingula were made from then extant specimens by three famous French scientists: BRUGUIÈRE, CUVIER, and LAMARCK. The genus Lingula was created in 1791 (not 1797) by BRUGUIÈRE and in 1801 LAMARCK named the first species L. anatina, which was then studied by CUVIER (1802). In 1812 the first fossil lingulids were discovered in the Mesozoic and Palaeozoic strata of the U.K.
