AB - ABSTRACT: At present in Colombia the Magdalena valley between the eastern and central ranges is the most important petroleum-producing section. Two geosynclinal areas of deposition are recognized, the North Andean geosyncline, Cretaceous and early Tertiary locus of deposition, and the downwarped Bolivar geosyncline between the present western and coastal ranges. Petroleum is found on asymmetric anticlines, in some places complexly folded.

AB - ABSTRACT: "The principal sedimentary basins are indicated on maps and the features of each discussed from the point of view of the petroleum geologist. The survey indicates large areas that are potentially petroliferous, and an attempt has been made to classify them into three groups: (a) most favorable, nb) moderately favorable, and (c) possibly petroliferous but for various reasons less promising.... Inaccessibility, unfavorable climate, and dense vegetation cover will retard exploration and development of the sub-Andean belt from northern Bolivia to central Colombia.".

AB - ABSTRACT: The bulk of Colombian petroleum production comes from two faulted anticlines in the middle Magdalena valley. Producing sands are Eocene and Oligocene. The Casabe field on the west side of Rio Magdalena produces from Tertiary sands. Cretaceous and Eocene horizons, complexly faulted, yield oil at the Barco concession in the southwest Maracaibo lake basin area.

AB - ABSTRACT: Exploration of the El Tabor manganese deposit of Agrado, Huila department, Colombia. The deposit lies in the Tertiary Honda formation. The manganese-bearing seams contain principally limonite, clay, and irregularly distributed oxides and hydroxides of manganese, partly pyrolusite, but principally wad, and to some extent simply manganese-bearing clay. The chemical compositions of several samples are given with reference to Mn, Fe, Al, and Si oxides.

Superficial laterites also occur with a low tenor of phosphorus. The total quantity of ore is much too low to have economic significance.

The ore is not of first quality, but is sufficiently good for use in manganese steel.
