    Orbital Cyclicities Above and Below the Cretaceous-Tertiary Boundary, Umbria-Marche Region, Italy (2000)
    In:  CASI
    Details
    Publication Date: 2004-12-03
    Description: In the Umbria-Marche region of central Italy, the deep basinal carbonate Scaglia Rossa Formation contains an important sequence of Cretaceous-Tertiary strata including a detailed paleomagnetic record and the distal impactoclastic Cretaceous-Tertiary boundary clay layer. In addition to this significant paleomagnetic and impactoclastic record, the Scaglia Rossa also contains potentially important stratigraphic evidence of relatively long-term oceanic and atmospheric consequences of the Cretaceous-Tertiary bolide catastrophe, which we will describe for the first time herein. Additional information is contained in the original extended abstract.

    Surficial Geology of the Chicxulub Impact Crater, Yucatan, Mexico (1993)
    In:  CASI
    Details
    Publication Date: 2019-07-13
    Description: The Chicxulub impact crater in northwestern Yucatan, Mexico is the primary candidate for the proposed impact that caused mass extinctions at the end of the Cretaceous Period. The crater is buried by up to a kilometer of Tertiary sediment and the most prominent surface expression is a ring of sink holes, known locally as cenotes, mapped with Landsat imagery. This 165 +/- 5 km diameter Cenote Ring demarcates a boundary between unfractured limestones inside the ring, and fractured limestones outside. The boundary forms a barrier to lateral ground water migration, resulting in increased flows, dissolution, and collapse thus forming the cenotes. The subsurface geology indicates that the fracturing that created the Cenote Ring is related to slumping in the rim of the buried crater, differential thicknesses in the rocks overlying the crater, or solution collapse within porous impact deposits. The Cenote Ring provides the most accurate position of the Chicxulub crater's center, and the associated faults, fractures, and stratigraphy indicate that the crater may be approx. 240 km in diameter.

    Chicxulub Impact Ejecta in Belize (1997)
    In:  Other Sources
    Details
    Publication Date: 2019-07-17
    Description: Chicxulub ejecta deposits in Belize provide the closest exposures of ejecta to the crater and the only exposures of proximal ejecta deposited in a terrestrial environment. A quarry on Albion Island in northern Belize exposes Late Cretaceous, possibly Maastrichtian, carbonate platform sediments that were folded, eroded, and subaerially weathered prior to the deposition of coarse ejecta from Chicxulub. These ejecta deposits are composed of a basal, about 1-m-thick clay and dolomite Spheroid Bed overlain by a about 15-m-thick coarse Diamictite Bed. Many and perhaps most of the clay spheroids are altered glass. Many dolomite spheroids have concentric layers and angular cores are probably of accretionary lapilli origin. A slight Ir concentration (111-152 ppt) was detected in the base of the Spheroid Bed. The Diamictite Bed contains about 10% altered glass, rare shocked quartz, 3-8 m diameter boulders and striated and polished cobbles, one with a penetrating rock chip that plastically deformed the cobble. Ejecta deposits extend to the surface at Albion and the maximum thickness in this area is not known. Ejecta deposits are exposed in several roadside quarries in the Cayo District of central Belize. The Late Cretaceous here is also represented by carbonate platform sediments. The upper surface of the carbonate platform is a highly irregular and extensively recrystallized horizon possibly representing deep karst weathering. Approximately 30 in of diamictite overlies this horizon with a texture similar to the Diamictite Bed at the Albion quarry, but with a more diverse lithology. In three locations the Cayo diamictites, contain red clay layers with abundant polished and striated limestone pebbles and cobbles called Pook's Pebbles, several of which have penetrating rock chips and ablated surfaces. We interpret the Albion Spheroid Bed as a deposit from the impact vapor plume and the Albion and Cayo diamictites as the result of a turbulent flow that contained debris derived from the ejecta curtain and local scouring. The polished, striated, and ablated Pook's Pebbles are interpreted as high altitude ballistic ejecta.

    Centros de escritura universitarios: una estrategia para la permanencia estudiantil (2022)
    Universidad Santiago de Cali

    Publication Date: 2024-04-14
    Description: Published
    Description: Las universidades colombianas han sido precursoras en la creación de centros y programas de escritura en Latinoamérica, así como en la producción y difusión de estudios sobre su labor. No es casual, entonces, que la iniciativa para la publicación de un nuevo libro haya surgido en el ámbito académico colombiano. Gracias a la convocatoria del Centro de Escritura, Lectura y Oralidad Académica de la Universidad Santiago de Cali (CELOA) nació Centros de escritura universitarios: Una estrategia para la permanencia estudiantil, un libro que reúne investigaciones llevadas a cabo por cinco centros de escritura de universidades colombianas. El título se nutre de la experiencia y de los trabajos de investigadores que desde hace décadas vienen aportando y reflexionando sobre la importancia de la escritura y la lectura para la construcción del saber y la comunicación de ideas. Entre las contribuciones más citadas por los autores de los capítulos se encuentran las de Paula Carlino, quien en su libro Escribir, leer y aprender en la universidad (Fondo de Cultura Económica, 2005) introdujo el concepto de “alfabetización académica”, que ha sido fundamental para desarrollar prácticas y profundizar en los estudios sobre la enseñanza terciaria.

    El CELOA- Trascendiendo la lectura, la escritura y la oralidad (2022)

    Description: Published
    Description: Leer, escribir y hablar en la universidad son habilidades que se van enriqueciendo con el paso del tiempo. Carlino, (2005) plantea el papel esencial de los docentes en el proceso de enseñanza aprendizaje de las situaciones didácticas y las condiciones institucionales en relación a las dificultades que presentan los estudiantes universitarios. Hace una reflexión en la búsqueda de respuesta al porqué los estudiantes no son reproducciones exactas de perfiles de aprendizajes y competencias previas esperadas para ser funcionales dentro del aula. Adicionalmente, aborda el problema de las competencias de escritura, lectura y oralidad en la universidad.
