Pollen rain in relation to arboreal vegetation in the Colombian cordillera oriental

Review of Palaeobotany and Palynology, 1980
Abstract The results are reported of a study of the relation between present-day arboreal vegetation types and their pollen rain (within the forests) in the Eastern Cordillera of Colombia. The vegetation cover was studied along 15 transects between 300 m and 4000 m above sea level.

Isotopic composition of lead in ore deposits of the Cordillera Oriental, southeastern Peru

Economic Geology, 1990
Twenty-five new lead isotope data are provided for 23 sulfide and 2 oxide minerals from 20 ore deposits embracing the wide variety of metallic mineralization present in the Cordillera de Carabaya, southeastern Peru, segment of the central Andean Inner Arc domain. The deposits are subdivided into the following groups: (1) Cu + or - W + or - Mo + or - Sn

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 ...

Sodium - a geochemical indicator of emerald mineralization in the Cordillera Oriental, Colombia

Journal of Geochemical Exploration, 1979
Abstract Emerald-bearing deposits in the Cordillera Oriental are structurally controlled, localized at the intersection of two fault systems. At these intersections zones of intense fracturing affected by sodium and carbonate metasomatism host the emerald mineralization.
