Paleontology and Stratigraphy of Fossils

Dredge samples collected from the continental slope off northern Chile and central to northern Peru elucidate the late Cenozoic geologic history of forearc. Late Miocene siltstone, claystone, and sandstone were recovered in water depths ranging from 2,779 to 8,132 m from the steep slope off Chile. Manganese slabs and crusts on these rocks and the virtual absence of Quaternary sediment cover suggest that this slope is a region of nondeposition.
