  • The Venezuelan Hydrocarbon Habitat, Part 1: Tectonics, Structure, Palaeogeography and Source Rocks
    Journal of Petroleum Geology, vo1.23(1), January 2000, pp 5-53. 5 THE VENEZUELAN HYDROCARBON HABITAT, PART 1: TECTONICS, STRUCTURE, PALAEOGEOGRAPHY AND SOURCE ROCKS K. H. James* Venezuela forms part of an important hydrocarbon province, defined by the presence of prolific Cretaceous source rocks, which extends across northern South America. By early 1997, the country had produced 53 billion barrels of oil. Reserves are estimated to total 73 billion barrels of oil and 146 TCF of gas with 250 billion barrels recoverable in the Heavy Oil Belt. Most reserves are located within the intermontane Maracaibo and foreland Barinas-Apure and Eastern Venezuela BasinxThey correspond to more than 1.5 trillion BOE originally in place. The province S hydrocarbon history began with a broad passive margin over which the sea transgressed throughout much ofthe Cretaceous. Limestones and shales followed basal sands and included rich source rocks. Convergence between the distal part of the area and the Caribbean Plate created an active margin that migrated southwards, so that flysch and wildflysch followed the transgressive facies. The process culminated in Lute Cretaceous to Middle Eocene orogeny with the emplacement of southward-vergent nappes and the development of northward-deepeningforedeeps. Flysch and wildflysch formed in the north while important deltaic - paralic reservoir sands accumulated in the south. Major phases of hydrocarbon generationfrom Jurassic-Cretaceoussource rocks occurred across the entire margin of northern South America during the orogeny. They are recorded by Jurassic - Middle Cretaceous graphitic marbles, schists and quartzites (metamorphosed, organic limestones and shales and oil-bearing sandstones) in the Coastal and Northern Ranges of Venezuela and Trinidad.

[email protected], [email protected] 2 Posgrado en Ciencias de La Tierra, Centro de Geociencias, Universidad Nacional Autónoma de México, Campus Juriquilla, Querétaro, México. [email protected] * Corresponding author: [email protected] ABSTRACT. The Yariguíes Anticlinorium, a regional structure located at the western flank of the Eastern Cordillera of Colombia, includes the thickest record of continental sedimentary rocks accumulated near to the Jurassic-Cretaceous boundary. The sedimentary rocks are lithoarenites and feldspathic arenites, grouped in the Girón Formation, and deposited in a Late Jurassic extensional basin interpreted in this work as a rift basin. We analysed the sedimentologic and compositional characteristics of two sections that accumulated in a complex rift system. We identified important thickness variations, from 3,350 m in the type section to at least 525 m in a reference section in the Zapatoca area, as well as petrographic and lithofacies changes. This led us to confirm that the Girón Formation encompasses all the continental facies, whose source rock correspond mainly to the exhumed blocks of the Santander Massif during the Late Jurassic. The synrift successions were segmented by transverse structures and regional longitudinal faults of the rift-shoulder, as the Suárez Fault. The tectonic frame of the study area shows the relevance of the W-E compressional regimes, explaining the local kinematics as a heritage of the former configuration and tectonic inversion of the basins.

JENNINGS1,2, LARS KROGMANN3 & STEVEN L. MEW2 1Australian Centre for Evolutionary Biology and Biodiversity, and 2School of Earth and Environmental Sciences, The University of Adelaide, SA 5005, Australia. Contact: [email protected] 3State Museum of Natural History Stuttgart, Entomology, Germany. Contact: [email protected] Abstract Hyptia deansi sp. nov. represents the first record of Evaniidae (Hymenoptera) from Lower Miocene to Upper Oligocene Mexi- can amber, Simojovel, Chiapas, Mexico and is described based on a well preserved female specimen. Phylogenetically relevant morphological characters are discussed with reference to fossil and extant genera of Evaniidae. The new fossil is placed in the extant New World genus Hyptia Illiger 1807, based on the presence of just a single fore wing cell, the absence of tubular veins M+CU, 1CUa, 1Cub, and the presence of 11 flagellomeres. Key words: amber, fossil, Lower Miocene, Upper Oligocene, Mexico, systematic palaeontology, Evanioidea Introduction Most Mexican amber originates from mines around Simojovel, Chiapas, Mexico. The amber-bearing strata extend from the Balumtun Sandstone of the Lower Miocene to the La Quinta Formation of the Upper Oligocene (Poinar & Brown 2002), with ages ranging from 22.5–26 Myr (Berggren & Van Couvering 1974). However, because the amber is found in secondary deposits, these dates only provide a minimum age. Mexican amber remains relatively poorly studied, although Solórzano Kraemer (2007) recently provided an extensive account of the insect inclusions, including a list of undescribed specimens from many insect orders and families.

Resumen A partir de la integración de información de campo, con datos petrográficos, geoquímicos de roca total, isotópicos y geocronológicos, se realizó la comparación de los diferentes segmentos que conforman el Arco Mocoa-Santa Marta (AMSM). Este arco, que aflora en el Valle Superior del Magdalena, la Serranía de San Lucas, la Sierra Nevada de Santa Marta y la Alta Guajira, se emplazó en un basamento Neo-proterozoico y en granitoides de un arco Pérmico, los cuales fueron posteriormente dispersados a lo largo de la Paleomargen Suramericana. El plutonismo del AMSM se caracteriza por la migración composicional en sentido W-E, con la formación de intrusivos de cuarzomonzonita, monzonita, charnoquita, tonalita y granodiorita hacia el occidente y la formación de plutones de monzogranito y sienogranito hacia el oriente; también existe un enriquecimiento en SiO2 en sentido S-N.

Email: [email protected] Abstract This study reports new data on the petrography, total rock chemistry and U-Pb zircon geochronology of volcanic rocks of the La Quinta Formation that outcrop the western flank of the Perijá mountain range and the Cesar and La Guajira departments. The volcanic rocks consist of basaltic, andesitic, dacitic and rhyolitic lavas, and the volcaniclastic rocks consist of crystal-vitric and crystal-lithic tuffs and agglomerates of calc-alkaline affinity, formed in a continental margin arc setting. Geochronological data suggest that the La Quinta Formation was volcanically active for approximately 25 Ma, during which its composition varied from basaltic trachyandesites to rhyolites. U-Pb dating suggests that the vol- canism began in approximately 191 Ma (Sinemurian age) and continued until approximately 164 Ma, with at least three periods of increased volcanic activity. The inherited zircons contain Triassic, Permian, Neoproterozoic and Mesopro- terozoic populations, indicating that this arc was emplaced on rocks of the Chibcha Terrane along the South American paleomargin and that it is part of the same arc that formed the Jurassic volcanic rocks of the Sierra Nevada de Santa Marta, Cocinas and San Lucas mountain ranges and the Upper Magdalena Valley.
