Influence of Salt in the Tectonic Development of the Frontal Thrust
t Special section: Balancing, restoration, and palinspastic reconstruction Influence of salt in the tectonic development of the frontal thrust belt of the eastern Cordillera (Guatiquía area, Colombian Andes) Vanessa Parravano1, Antonio Teixell2, and Andrés Mora3 Abstract Geologic maps, seismic lines, and data from a dry exploration well were used to develop a new structural model for a segment of the eastern foothills of the Eastern Cordillera of Colombia, emphasizing the role of salt tectonics. Milestones in the deformation history of the Guatiquía foothills were studied by sequential section restoration to selected steps. Uncommon structural geometries and sparse salt occurrences were interpreted in terms of a kinematic evolution in which Cretaceous salt migration in extension produced a diapiric salt wall, which was subsequently welded during the main episodes of the Andean compression, when the salt wall was squeezed generating a large overturned flap. Salt-weld strain hardening resulted in breakthrough thrust- ing across the overturned flap in late deformation stages. We have evaluated a pattern of salt tectonics pre- viously unrecognized in the foothills thrust belt, which may be significant in other parts of the external Colombian Andes. Introduction We aim to provide an explanation for differences in The prolific thrust belt of the eastern foothills of the structural style in the EC external thrust belt.

The Cretaceous Source Rocks from East Venezuela – Trinidad-Guyana/Suriname Basins, NE South America
The Cretaceous source rocks from East Venezuela – Trinidad-Guyana/Suriname basins, NE South America Francia A. Galea Alvarez, PhD Actus Veritas Geoscience, LLC 1st HGS/EAGE Conference on Latin America: South American Petroleum Play for Future Decades of the Third Millennium. Houston, November 19 – 20, 2019 Abstract The Cretaceous source rocks from East Venezuela - Trinidad - Guyana/Suriname basins, NE South America Galea Alvarez, Francia A. – Actus Veritas Geoscience, LLC The major contribution to the oil fields in East Venezuela and Trinidad are Cretaceous source rocks, Late Albian – Santonian in age. The Querecual Formation, from the Guayuta Group, is the source rock of the oil and gas from the giant and super giant oil fields like Carito, Furrial_Musipan, Quiriquire, Great Oficina, Anaco Trend, and Santa Barbara oil fields, among others. The Orinoco Belt huge deposits of oil are aromatic-asphaltic oils biodegraded interpreted as originated in organic rich carbonate sediments, with some components of siliciclastic, deposited in an anoxic environment as the one described for the Querecual Formation at the type section and outcrops around the Pozuelos Bay, northern Anzoátegui state, southwest of the Cariaco Basin. Studies at the type section of the Querecual Formation described black shales, limestones and marls, rich in foraminifers and other macrofossils, which were used to identify biostratigraphic zones from late Albian to Santonian, and a hiatus at the early Cenomanian. Paleowater depths were interpreted as middle to upper bathyal (based on microfossils content). Mainly microlaminated foraminiferal microfacies were linked to anoxic-dysoxic levels. Total carbon (TC), Total organic Carbon (TOC), inorganic carbon (Cinorg), and total Sulfur (tS), and the calcium carbonate concentration (CaCO3) were measured and interpreted: high values of CaCO3, of the TOC and planktonic foraminifers decreases from base to top, and were identified in strata from late Cenomanian, late Turonian, Coniacian and Santonian. -

Emeralds in the Eastern Cordillera of Colombia

On the western side of the Eastern Cordillera, the deposits are linked by tear faults and associated thrusts developed during a compressive tectonic phase that occurred at the time of the Eocene- Oligocene boundary, prior to the major uplift of the Cordillera during the Andean phase (middle Miocene). On the eastern side of the Cordillera, emerald mineralization occurred earlier, at the time of the Cretaceous-Tertiaryboundary, during a thin-skinned extensional tectonic event linked to evaporite dissolution. This event predates the Andean phase, during which this part of the chain was folded and thrust over the Llanos foreland.

PARRA ICP, Bucaramanga, Km 7 via Piedecuesta, Colombia ABSTRACT: The two major oil fields in Colombia discovered in the last fifty years are the Caño Limón and Cusiana fields. Caño Limón is located in the eastern region of the unfolded Llanos of Colombia, and Cusiana is located in the leading thrust sheet of the Llanos Foothills. Paleogene strata in both areas were part of a large foreland basin active since the latest Cretaceous. In both cases the main reservoir is a quartz arenite unit, informally called the Mirador formation, that has always been assumed to extend as a continuous Eocene sandstone layer from the Llanos Foothills into the Llanos Basin. However, recent palynological data suggested that this unit is diachronous across the Llanos and Llanos Foothills. Here, we dated 44 sections in the Llanos Basin and Llanos Foothills using a new zonation that is proposed for the region. Biostratigraphic results constrain the age of the Mirador Formation in the Llanos Foothills as early to middle Eocene with no evidence of a biostratigraphic gap with underlying early Eocene strata. -
