AB - ABSTRACT: "An early Paleozoic (mainly Ordovician) geosyncline was probably present in the area of the east cordillera, but its sediments were to a large extent greatly metamorphosed or eroded in later periods. Caledonian folding is indicated in the Perija range. Thick Devonian, Carboniferous, and Permian marine deposits were folded in late Permian or more likely lower Triassic orogenic phases, and to a large extent they were eroded. Marine upper Triassic with strong affinities with the Peruvian Triassic has been found in the upper Magdalena valley. . . . Marine lower Jurassic is known only from the El Banco district. Triassic and Jurassic are chiefly red beds with variable amounts of effusive and intrusive igneous rocks.".

Three physiographic provinces are present in the district, the east slope of the Cordillera Central, the Llanos subprovince, and the west slope of the Cordillera Oriental. A former ponding of the Magdalena is named "Lake Hettner." The entire stratigraphic sequence from Oligocene to recent is nonmarine.

AB - ABSTRACT: The pre-Mesozoic rocks of northern South America include igneous-metamorphic complexes of uncertain age and also scattered erosional remnants of the sedimentary rocks of several Paleozoic systems. About the close of the Paleozoic a crustal revolution took place. Triassic and Jurassic formations have been determined in northern Peru, Colombia, Venezuela, Trinidad, and Guiana. In late Jurassic time there appears to have been a major crustal disturbance. Cretaceous deposition is found in northern Peru, Ecuador, Colombia, Venezuela, and Trinidad. At the close of the Mesozoic broad positive epeirogenic movements were in progress. A list of 54 references closes the paper.
