The Bohío Formation (Tbo, Tbm)period.[2]
Description
The Bohío Formation is characterized by the presence of poorly sorted debris, mostly
subgraywacke. The Bohío Formation overlies the Gatuncillo Formation
conformably in most areas, although may lap onto the Gatuncillo Formation or basement.
The thickness of the formation is about 75 to 450 metres (246 to 1,476 ft). Smaller foraminifera from the basal part of the formation yielded an early Oligocene age. The upper part of the formation, from which the collections are derived yields larger foraminifera of late Oligocene age.[3]
