Sediment accumulation history for the Quebrada la Porcelana area based on magnetostratigraphic ating of Neogene overburden strata: Using outcrop thicknesses, the Los Monos Formation passed through the generation depth (assumed to be 4 km; red arrows) during the 4.8-4.1 Ma interval (green arrows). Growth strata deposition commenced about 5.2 Ma (purple arrows).
