Summary of Geology and Rock Physical Properties Route 17.
Abstract
This report of the Atlantic-Pacific Interoceanic Canal Study Commission describes Eastern Panama as a former vocanic area, still subject to earthquakes. The region comprises 3 major physiographic provinces: the Pacific highlands, the Central lowlands, and the highlands of the Continental Divide. The rocks are igneous, pyroclastic, and sedimentary, and the geologic structure varies from complex to simple in different areas. The residual clayey and silty soils of the area, produced by tropical weathering, are generally less than 20 feet thick. Beneath them lies a variable mantle of weathered rock. The annual wet and dry season cause a notable fluctuation in the ground water table. The rocks range considerably in strength, and include the following types: Strong basalts, tuffs, agglomerates, and tuffaceous limestones; medium-strength tuffs, agglomerates, and tuffaceous limestones; and weak calcareous and non-calcareous tuffs, tuffaceous siltstones and sandstones, shaly limestones, and shales. The strength of the rocks correlates well with the topography they support.
