Sedimentology, Stratigraphic Architecture, and Ichnology of Gravity-Flow Deposits Partially Ponded in a Growth-Fault-Controlled Slope Minibasin, Tres Pasos Formation (Cretaceous), Southern Chile

摘要

A recent resurgence in the study of slope deposits is strongly related to the complexity inherent with the depositional setting, and the continued prospectivity for hydrocarbons in associated units. Intraslope basins are particularly intriguing to explorationists, because they provide accommodation space for coarse-grained facies in areas often characterized by otherwise muddy deposits. An outstanding outcrop of a growth-fault-controlled slope minibasin and its sandy fill are exposed in Cretaceous strata of southern Chile.
