Fig. 9From: Hyperpycnal (over density) flows and depositsDiagram showing the evolution of subaerial derived concentrated flows when entering a marine or lacustrine basin. Only the deposit (F4–F5 facies) accumulated from the original flow can eventually display diagnostic characteristics of a hyperpycnal origin, since light extrabasinal materials will be lost during water entrainment and the hydraulic jump. Facies classification is after Mutti 1992Back to article page
