AB - ABSTRACT: The Cretaceous (Aptian?) Yavi Formation in the Upper Magdalena Valley basin consists of continental red beds deposited within a back-arc basin on the eastern margin of the Central Cordillera in the Colombian Andes. A systematic stratigraphic variation in sandstone composition within the sequence reveals a climatic change during deposition, ranging from semiarid to semihumid-humid. In addition, this climatic shift has an effect on the authigenic mineralogy, at least in the type section where the samples for this work were collected. The diagenetic changes recorded in the Yavi Formation can be described by six main episodes of cementation coupled with compaction as seen by the presence of pseudomatrix (or squeezed grains) throughout the sequence. From bottom to top, these six episodes are characterized primarily by: 1) microcrystalline quartz and chalcedony; 2) carbonates; 3) phyllosilicates; 4) phyllosilicates and opal; 5) phyllosilicates and carbonates; and 6) phyllosilicates, microcrystalline quartz and chalcedony. This diagenetic pattern seems to be independent of detrital mineral composition and mostly controlled by climatically influenced pore-water chemistry. The presence of quartz and chalcedony is interpreted to have formed during relative semi-humid conditions whereas the carbonate cement and phyllosilicates formed during more arid conditions. The Yavi Formation is characterized by its compositional immaturity and poor sorting that resulted in low initial porosity. Further reduction of porosity was accomplished by pore filling cement, as described above. The lack of porosity in these sandstones precludes them as hydrocarbon reservoirs in the Upper Magdalena Valley, unlike the more mature quartzose sandstones overlying this sequence.

AB - ABSTRACT: In this study oil gas chromatography (GC) data is integrated with geologic and engineering information to define the reservoir compartments in the Yarigui-Cantagallo field. The trap (area 55 km2) is a southeast dipping, wedge shaped monocline bounded to the west by the northeast trending Cantagallo Fault. It is further dissected by secondary, longitudinal and transverse faults. The field produces heavy oils. The main producing horizons are the "Cantagallo" sands (alluvial and stacked braided channels) of the Eocene La Paz Formation. The overlying "C" sands (braided channels) of the La Paz Formation and the "B" sands (meandering channels) of the Oligocene Mugrosa Formation are secondary producers. Comparison of GC fingerprints of oils produced from the "Cantagallo" sands in twenty four wells indicate lateral fluid continuity among the "Cantagallo" sands within and across the different fault blocks. GC data of oils from the "C" sands in six wells show they belong to isolated reservoirs. GC data from the commingled oils (ten from "Cantagallo" and "C", one from "C" and "B") have identified their real contributing zones. The oils were derived from the Cretaceous La Luna Formation and show similar thermal maturity. Differences in oil alteration in different reservoir compartments were responsible for their distinct oil fingerprints. Integration of the GC data with information on structure, reservoir distribution, oil-water contacts, initial pressure and pressure history, has led to modification of the structural interpretation, and has helped identify the reservoir compartments consistent with all data.

AB - ABSTRACT: The Medina anticline is a fault-bend fold located in the hanging wall of the Aguaclara fault along the southeastern thrust front of the Eastern Cordillera of Colombia, a petroleum province with giant fields. We employ a modified technique of axial-surface analysis using fold-evolution matrices, which helps define the subsurface geometry and thereby provides important constraints on trap geometry, modeling of hydrocarbon migration pathways, and prediction of reservoir quality. Fold-evolution matrices illustrate the effects of two independent variables on cross-sectional fold geometry. Three matrices are presented for fault-bend folds in which the fault shape is controlled by a preexisting rift-basin architecture. In each case, variation in displacement is plotted against change in fault geometry: increasing ramp height, decreasing ramp dip, and increasing length of an intermediate flat. The matrices are used to construct synthetic axial-trace maps and corresponding block diagrams in which one or both parameters vary along strike. The synthetic maps can be compared to axial-trace maps of real folds and used in conjunction with other data and methods to provide a better understanding of fold geometry and genesis. Axial-surface analysis of the Medina anticline shows that the three-dimensional fold geometry is compatible with a model in which three parameters vary along strike: (1) increasing fault displacement to the northeast, (2) increasing length of an intermediate flat to the northeast, and (3) decreasing ramp dip to the southwest. The model is used to construct the three-dimensional fault geometry, which is characterized by a ramp-flat-ramp segment to the northeast and an oblique ramp to the southwest. The Medina anticline formed during Tertiary inversion of a Jurassic rift basin, where preexisting normal faults controlled the position and orientation of ramps in the Aguaclara fault.

AB - ABSTRACT: Galeras, a volcano in the south of Colombia, has historically been very active. Nevertheless, the memory of the tragic eruption of Nevado del Ruiz in 1985 caused great anxiety in the surrounding region as the first signs of reawakening were perceived in early 1989. Decision makers were unprepared as they tried to organize their communities. The media were obsessed with another potential tragedy, the community scared and disoriented. Banks, businesses and traders--seriously affected by the uncertainties of the situation--forced the regional and local authorities to ignore the volcano activity. The relationship between scientists, the authorities and the community suffered from inappropriate management of the situation. Seismic swarms that could be felt and eruptions that were observed in 1993 helped to focus the minds of all involved. Recently, the relative quietness of the volcano has allowed scientists, the authorities and the community to achieve remarkable results. Awareness of the hazards is now growing among the community. Policies need to be implemented while the volcano is dormant.

AB - ABSTRACT: Magdalena river discharges 228 km (super 3) of water annually, or on the average 7200 m (super 3) s (super -1) , into the western Caribbean based on 21years of daily data, 1975-1995. The mean sediment load for the Magdalena is 144X10 (super 6) t yr (super -1) , corresponding to a sediment yield of 560 t km (super -2) yr (super -1) for the 257,438 km (super 2) basin. Magdalena is the largest river discharging directly into the Caribbean Sea, and it has the highest sediment yield of any medium-sized or large river along the entire east coast of South America. Magdalena sediment load is well correlated with water discharge (R (super 2) = 0.76). Regression of water discharge on the Southern Oscillation Index (SOI) shows that 69% of the variability of the Magdalena streamflow is explained by the SOI, with high discharge occurring during La Nina phase and low discharge during El Nino phase. Cross-spectral analysis between Magdalena discharge and the SOI indicates an average recurrence interval of 3.0 years with a coherence, Y (super 2) = 0.90, and that the discharge anomaly is in phase with the SOI anomaly. Analysis of time series of sediment load, 1975-1995, indicates that la Nina phase is characterized by a sediment load as high as 1600X10 (super 3) t day (super -1) . Sediment load is also correlated with SOI with a coefficient of variation of R (super 2) = 0.54. Clearly, the Magdalena water discharge and sediment load are strongly coupled to the El Nino-La Nina cycle.

AB - ABSTRACT: The study of a cranium and its pertinent jaw-bone collected in sediments of the Honda Group, Upper Miocene of La Venta (Huila, Colombia) permits the proposal of Brievabradys laventensis gen. et sp. nov. To this species is attributed the specimen that Hirschfeld (1985) had described as "Small Nothrothere" and the material described by McDonald (1997) as an Argentine species, Glossotheriopsis pascuali. On the other hand, the comparison of B. laventensis with Orophodon hapaloides, as well as the evaluation of the diagnostic aspects of the family Orophodontidae allow assignment of Or. hapaloides to the subfamily Mylodontinae (Mylodontidae).
