Summary: The Miocene siliceous and calcareous sediments vary with depth. The variations reflect crustal disturbance and calcite compensation depth changes, as well as geographical and surface-water composition changes. The chemical data show that the Pleistocene and one Lower Pliocene ash beds are rhyolitic and related to South American ignimbrites; the ash is minor in the sediments because of bioturbation. Temperatures of 50°C have aided the formation of chert beds and accelerated the induration of the sediments.
