Hydrocarbon–metal associations in the Western Cordillera, Central Peru

Journal of Geochemical Exploration, 2000
Abstract There are a large number of solid bitumen veins in Central Peru which are known to be ubiquitously enriched in vanadium. The bitumen was emplaced as a viscous fluid under pressure, directly influenced by the igneous and tectonic activity in the Western Cordillera.

Geothermal exploration in the northern block of the Central Cordillera of the Colombian Andes

First EAGE Workshop on Geothermal Energy in Latin America, 2021
Summary Is presented a summary of the progress of the exploration (geological and geochemical) of three geothermal areas located in the northern block of the Colombian Andes mountain range, associated with the volcanism, due to the subduction of the Pacific between the Nazca and the South American plates.

Gravity profile of Central Cordillera, Northern Luzon

Journal of Asian Earth Sciences, 1997
Abstract In 1990, a land gravity survey was conducted approximately in an E-W traverse acrossthe Central Cordillera Mountains in Northern Luzon, Philippines. The purpose was to calibrate a digital elevation model for the Philippines. However, the gravity profile intersected the main tectonic fabric of the region, passing through the Baguio Mining ...

Climosequence of Ash‐Derived Soils in the Central Cordillera of Colombia

Soil Science Society of America Journal, 1972
Abstract Four soils derived from volcanic ash were studied in a transect on the east slope of the Central Cordillera of Colombia. Average annual temperatures range from 8C at 3,670 m altitude to 24C at 980 m. Only the soils located in the lower part of the transect have B horizons.

Fog interception in montane forests across the Central Cordillera of Panamá

Journal of Tropical Ecology, 1996
ABSTRACTFog interception and rainfall were measured at 14 stations across the Central Cordillera in western Panamá. Fog interception and rainfall were measured monthly during 1988–1989 with artificial fog catchers and rain gauges, respectively. Fog interception was highest on ridges and increased with increasing altitude.

Sedimentology of Large Olistoliths, Southern Cordillera Central, Hispaniola

SEPM Journal of Sedimentary Research, 1992
ABSTRACT More than 500 large, well exposed, calcareous olistoliths of Paleocene to Eocene age are exposed in the Eocene deep-water Rio Ocoa Formation of southern Hispaniola. Due to the low degree of tectonic overprint, their sedimentary characteristics can be studied in detail. The olistoliths reach up to 6 km in length and are largely conformable with

Petrogenetic and Metallogenetic Relationships in the Eastern Cordillera Occidental of Central Peru

The Journal of Geology, 2009
Abstract Ore deposits spatially and temporally related to high‐K calc‐alkaline intrusions or domes are widespread in the central Peruvian Cordillera Occidental. Geochronology and petrochemistry of intrusive rocks associated with mineralization reveal that most ore deposits (1) were emplaced in the late Middle to early late Miocene and (2) are related ...

Plant Phenological Patterns in the High Andean Cordillera of Central Chile

The Journal of Ecology, 1981
(1) Vegetative activity and flowering and fruiting records are given for ninety-seven species from three vegetational belts in the andean (alpine) zone of the Cordon del Cepo (33017'S, 70016'W), Cordillera de los Andes, central Chile. Comparisons of phenological behaviour and overall phenological patterns were made at six altitudes between 2320 and ...

Crustal and uppermost mantle velocity structure beneath the Cordillera Central and Cordillera Oriental, Dominican Republic

The oblique convergence between the Caribbean and North American plates produces the tectonic complexity of Hispaniola Island. The western region is characterized by high topography bounded by dominantly reverse and oblique-slip faults along the edges of the uplifted mountain ranges, while the eastern part is lower in elevation and no important active ...
