Summary of geology and rock physical properties Route 25
Technical Report

OSTI ID:7317315
This summary, for the Atlantic-Pacific Interoceanic Canal Study Commission, deals principally with the Pacific portion of Route 25, where nuclear excavation may be applicable. Physiographically Route 25 is composed of the small and discontinuous Pacific strand, the Choco and Saltos highlands, and the Atrato lowland, which continues from the Saltos highlands to the Gulf of Uraba. Near the Upper Truando Valley, the route crosses about two miles of sedimentary rocks of the Sautata and Nercua groups, Which, since they support rugged topography and are firm in outcrops, are believed to be competent. The structural geology of the area is characterized by abundant faulting. Although no complete picture of the regional geology has been developed, the main structural elements of the area are the Serrania de Baudo, the Bolivar geosyncline, and the Cordillera Occidental and its structural continuations, the buried Sautata Arch and the Serrania del Darien.
