Description
The Belgrade Formation is composed of two subunits: the Pollocksville Member and the Haywood Landing member. The Pollocksville member is composed of unconsolidated oyster shells and sand. It was deposited in the early Miocene. The Haywood Landing member is composed of shelly sands and thinly laminated clays. The Belgrade Formation was originally considered part of an Eocene formation called the Trent Marl before it was identified as being deposited in the Miocene and split off.[1]
