AB - ABSTRACT: The emerald mine near Muzo, some 100 kilometers north of Bogota, Colombia, is located in terrain composed of lower Cretaceous bedded rocks. The emeralds occur principally in calcite lenses, occasionally in dolomite beds, in dislocated fine-grained shales discordantly overlying black schists. Formation of the emeralds is attributed to the second of three stages of mineralization associated with deep-seated igneous activity which must have occurred after the lower Cretaceous. Although no granitic massif has been found, pegmatite veins, extensive albitization, and other evidences of magmatic activity occur widely.

AB - ABSTRACT: Individual reports outline the beginning stages of investigations of world-wide age correlations of the Precambrian in Australia, South Africa, Brazil, Venezuela, Colombia, the southern Atlantic states, islands in the Caribbean, the northern Appalachian province, Nova Scotia, Newfoundland, and the Canadian Shield area including Labrador. The most interesting observation during the year has been the increase of localities in different continents that have been found to show similar age groupings. The 2,600 million years age has now appeared in Ontario, Quebec, the Northwest Territories (Yellowknife belt), Karelia, S. and central Africa, India, Australia, and Brazil. The 1,700 m.y. age (+ or - 100 million years) is appearing in northern Manitoba, S. Greenland, central Fennoscandia, the metamorphic belt involving the Huronian sections of the Great Lakes region extending from the Sudbury district into Minnesota, at least parts of Labrador, India, central Africa, and the Northern Territory of Australia. Similar statements may be made regarding the typical Grenville age of about 1,000 m. y. and the typical latest Precambrian age in the vicinity of 500 m.y. Another observation, first noted by Arthur Holmes, is that by far the greatest proportion of the world's Au production comes from the 2,600 million year old provinces. These include the Au mines of Ontario and Quebec, the Yellowknife district in the Northwest Territories, Mysore and Kolar Au fields in India, Kalgoorlie and other Au fields in Western Australia, the ancient crystalline source area of the Witwatersrand Au district in South Africa, and now a possibility of the Au region in Minas Gerais, Brazil. There must be a good geological explanation for this strong association. Another observation has been that the range of ages from 300-400 m.y. found in Nova Scotia seems to agree with a similar range across the Piedmont in Georgia and in southern New England. The age of the post lower-Middle Devonian intrusives, where stratigraphic relationships are observed, must therefore be measured individually, rather than be determined from an average for the belt as a whole.

AB - ABSTRACT: "This region is in the western part of the Maracaibo-Falcon basin and during the early Oligocene also formed part of another structural basin that extended westward from the Bolivar coastal area to the Magdalena basin area of Colombia. As a result of the regional uplift at the end of the Eocene, piedmont fans, lagunal, lacustrine and coastal plain sediments were deposited outward from the recently formed mountains toward the center of the valleys. The marine transgression of the upper Oligocene spread westward through the states of Falcon and Zulia until it reached Boscan field, so that the upper Oligocene is characterized by an interfingering of marine, brackish water and coastal plain sediments. The Miocene is characterized, in the eastern part of the area, by a decrease in the marine influence and the predominance of very brackish water and terrestrial environments, with the deposition of a great thickness of clays and silts.".

AB - ABSTRACT: The region between San Gil and Chiquinquira in the Cordillera Oriental of Colombia is characterized by extensive tabular areas and broad asymmetric folds developed in Cretaceous formations which transgressively overlie basement rocks and, in places, sedimentary deposits of the Giron formation (Triassic-Jurassic). The Cretaceous section decreases in thickness from south to north. Structural features reflect the effects of vertical dislocations in the basement, which, depending on the proximity to the surface, resulted in either broad folds, as in the southern part where the basement is at considerable depth, or in fault structures, as in the north, where the basement is near the surface.

AB - ABSTRACT: Carbonate concretions containing well-preserved remains of fish or other marine organisms occur in middle Cretaceous black calcareous shales in the Magdalena valley, Colombia. Their formation may have been due to a local increase in pH, sufficient to cause precipitation of calcium carbonate, as a result of ammonia or amines released during decomposition of the organism.
