McLennan, Raymond Levey, Néstor Martínez-Romero Editorial Como sabemos el análisis petrográfico y mineralógico de rocas, bajo el microscopio petrográfico y electrónico de barrido, ha sido una disciplina que proporciona al geólogo petrolero evidencias directas de la calidad de rocas generadoras, almacenadoras y sellos, además de proporcionarnos datos de las características intrínsecas de estas rocas para interpretar sus orígenes. El geólogo que realiza un estudio petrográfico requiere del conocimiento profundo de varias ciencias, entre ellas, cristalografía, diagénesis, sedimentología, paleontología, geoquímica, etc., para poder interpretar lo que está observando. Varios de nuestros asociados tienen una amplia experiencia en esta disciplina, pero cada día es menos común entre los jóvenes profesionistas. Aquellos que dominan esta disciplina podrán atestiguar lo apasionante que es el estudio de las rocas a esta escala, que últimamente también se ha usado para detallar cuestiones tan especializadas como la determinación de características o atributos de fracturas naturales de los yacimientos más importantes de nuestro país. En este Boletín de la AMGP, se incluyen dos trabajos técnicos: el primero es una investigación e integración de una base de datos petrográficos y de clasificación y madurez textural de areniscas de varias áreas, con el objetivo de buscar una firma que identifique y caracterice a un tipo de cuenca en específico. Además, propone un método, que junto con la estadística podría determinar, según los autores, la proveniencia y tipo de cuenca de los componentes que conforman estas rocas. Como ejemplo, los autores analizaron las areniscas de cuatro formaciones del noreste de México, concluyendo que los componentes provienen de cuencas de tipo rift, cuenca tras arco extensional y strike-slip. Este es un trabajo que principalmente tiene una aplicación directa en el estudio de plays terciarios productores del país. El segundo trabajo de este Boletín, es un ejemplo de un análisis mineralógico y de porosidad en carbonatos de la Fm. Pimienta, de la Cuenca Tampico Misantla, enfocada a evaluar el potencial no convencional de esta formación. El objetivo principal, de acuerdo a los autores, es elaborar una descripción detallada a nivel micro y nano escala para comprender las implicaciones, de las propiedades petrofísicas y de la distribución de porosidad, en la capacidad de almacenamiento de hidrocarburos, el flujo de fluidos y la permeabilidad de esta formación. Con base a 12 muestras de siete pozos, usando microscopia de barrido y pruebas de difracción de rayos x, muestran un análisis detallado de la composición química, morfológica, tipo de materia orgánica y distribución de porosidad. Basado en los resultados de este estudio, los autores determinan que la Fm. Pimienta es análoga a las formaciones Eagle Ford y Bakken de Norte América, sin embargo, concluyen que, si bien el área analizada no tiene propiedades óptimas, es posible encontrar zonas estructurales en donde las propiedades geoquímicas y petrofísicas puedan conformar un yacimiento no convencional con potencial comercial. A pesar de esto, este trabajo es sin duda un aporte de datos importantes en el estudio de plays no convencionales en nuestro país y enriquece el conocimiento que tenemos de este tipo de yacimientos.

CP. 78290 Submitted to Boletín de la Asociación Mexicana de Geólogos Petroleros, February 2018. ABSTRACT This work develops a statistical bivariate analysis and a discriminant analysis on 1411 sandstones from nine types of sedimentary basins. The study rates the variations of framework components and differentiates the modal composition for each basin by partitioning the data into discriminant fields in a ternary plot. The discriminant analysis of the full sedimentary framework petrography indices improves the use of ternary sub- compositions (Qm, Qp, P, K, Lv, Ls, Lm), and provides additional support for sandstone provenance analysis. Petrographic indices in basins related to subduction represent the processes of major newly formed source- areas like intra-oceanic arcs and continental-margin arcs. Indices in rift, foreland, and accretionary basins indicate sedimentary processes like particle sorting, textural maturity, and the exhumation/unroofing of the sedimentary carapace. In contrast, the indices strike-slip basins hold a mixture of the processes previously described, but with significant input from crystalline and metamorphic rocks. The analyses with statistical and discriminant methods are for interpreting which basins occur where some sandstones deposited in the Sierra Madre Oriental northeastern Mexico. This exploratory method is for Upper Triassic–Lower Cretaceous sandstones selected from four different formations: El Alamar, La Boca, La Joya, and La Casita. The framework composition in sandstones discriminates among the types of basins in a ternary plot. The analysis indicates a rift, forearc, and strike-slip basins, respectively, to the age of the formations from Late Triassic, Early–Middle Jurassic, Middle Jurassic, and Late Jurassic to Early

Abstract. – Reinvestigation of a partial vertebral column from the Kimmeridgian La Caja Formation of Mexico, housed in the University of Linares (Mexico), and previously attributed to a dinosaur, proves to be from a very large pliosaurid plesiosaur. This specimen represents the first plesiosaur described from the Jurassic of Mexico. Its length has been esti- mated at 15 metres and, as a juvenile, is considered to be one of the largest Jurassic marine reptiles. The remains of this animal are here described. The morphology of the vertebral column is not diagnostic beyond family level. Large pliosaur vertebrae of a similar size are known from the Upper Jurassic of Europe, and are often referred to the genera Liopleurodon or Simolestes but these identifications are based only upon the size of the centra and have no taxonomic justification. A portion of rostrum with teeth was discovered together with the vertebral column but is unfortunately now lost. The Mexican pliosaur fills geographical and chronological gaps between western Tethys and South American pliosaurs, and is an additional support to the hypothesis of a Hispanic corridor linking at least temporarily the NW Euro- pean marine province with the western South American marine (Pacific) realm during the late Jurassic.

[email protected] ABSTRACT – IGM 9026 is a singular fossil collected at the beginning of the 20th century in an improperly documented site within the Tlaxiaco Basin, near to Tlaxiaco town, Oaxaca, Mexico. The age of the site was suggested as being early Cretaceous. This specimen is the holotype of Plesiosaurus (Polypticodon) mexicanus, which later was identified as a possible late Jurassic marine crocodylomorph of the family Metriorhynchidae, and consequently it was referred as ?Cricosaurus mexicanus. The present study provides a re-description of this fossil based on a microscopic analysis and the use of white and UV lights; these analyses led to the discovery of peculiar dental characters diagnostic of the genus Torvoneustes. This finding supports the re-classification of IGM 9026 under a new nominal combination asTorvoneustes mexicanus.

Las Cruces, New Mexico 88003, United States of America * [email protected] Abstract Carbonate strata that occur as blocks encased in gypsum of three different salt diapirs in La Popa Basin contain a single invertebrate fauna indicating a Late Jurassic (Kimmeridgian) age for all sampled fossiliferous blocks. The most biostratigraphically significant species, present in all diapirs, is the gryphaeid oyster Nanogyra virgula. Other species identified in the blocks include the bivalves Astarte gracilicostula, Cercomya durangensis, Myophorella sp., Grammatodon sp. and the nautiloid Cymatoceras? sp. Geologic relations of the entire assemblage of carbonate blocks, including nodular gypsum interbedded with the fossiliferous beds, salt casts in micrite of the blocks, random structural position of blocks within the diapiric evaporite, absence of blocks younger than Early Kimmeridgian in the diapirs, and regional stratigraphic relations, suggest that the carbonate strata were originally interbedded with, or directly overlie, evaporite strata. This inference is corroborated by the presence of Nanogyra virgula (previously reported as Exogyra cf. E. susplicifera) in carbonate strata directly overlying massive gypsum at Potrero Minas Viejas, adjacent to La Popa Basin.

  • Thesis Structural Evolution of the Potosí Uplift, Sierra
    THESIS STRUCTURAL EVOLUTION OF THE POTOSÍ UPLIFT, SIERRA MADRE ORIENTAL, NORTHEASTERN MEXICO Submitted by Stewart Alexander Williams Department of Geosciences In partial fulfillment of the requirements For the Degree of Master of Science Colorado State University Fort Collins, Colorado Fall 2019 Master’s Committee: Advisor: John Singleton John Ridley Melinda Laituri Copyright by Stewart Alexander Williams 2019 All Rights Reserved ABSTRACT STRUCTURAL EVOLUTION OF THE POTOSÍ UPLIFT, SIERRA MADRE ORIENTAL, NORTHEASTERN MEXICO The Jurassic Minas Viejas Formation is host to a Late Cretaceous to early Paleogene-aged décollement in the Sierra Madre Oriental, Mexico. The Minas Viejas Formation is dominated by rheologically-weak evaporite that accommodated thin-skinned deformation, forming the Sierra Madre Oriental fold-thrust belt with minimal deformation to the underlying Triassic-Jurassic red beds. Thin-skinned shortening above the décollement temporally transitioned to thick-skinned shortening, resulting in exhumation of the décollement and development of the Potosí uplift, one of the largest and well exposed thick-skinned uplifts in the orogen. Detailed geologic mapping and structural analysis provide insight into the geometry and kinematics of the Potosí uplift, and (U-Th)/He thermochronometry and vitrinite reflectance record the burial history and timing of exhumation associated with the uplift. Thick-skinned deformation involved folding of sub-décollement strata into a NNW-SSE- striking anticlinorium, development of cleavage, ENE-WSW directed thrust faulting, conjugate strike-slip faulting, and formation of ENE-WSW-striking extension fractures associated with barite mineralization. These structures consistently record ENE-directed subhorizontal shortening. Shortening is directed ~062° in the southern part of the uplift and ~077° in the northern part of ii the uplift.
