An eocene storm-generated littoral placer, northeast Otago

Abstract

Abundant hummocky cross stratification at the base of the Tapui Glauconitic Sandstone in the Livingstone—Maerewhenua area, North Otago, New Zealand, indicates a stormdominated shallow marine environment. Heavy mineral concentrations, including gold, in the hummocky cross stratification strata reflect sublittoral placer development during storms. © Crown copyright 1988.
