Ablation Point

At Ablation Point, this formation is characterized by a wide range of slump-folded and rafted blocks of sedimentary and volcanic strata that occur chaotic, laterally discontinuous beds that are part of the deposits a single, large, deep-sea submarine slump.

The Ablation Point Formation exhibits numerous internal unconformities and irregular, erosional contacts.

Fossils of ammonites, belemnites, and bivalves are sparse and poorly preserved within the Ablation Point Formation.

It consists of conglomerates, immature arkosic sandstones, and mudstones which were deposited in deep sea fans.

The strata of Himalia Ridge Formation is only the base of a 2.7 km (1.7 mi) thick sequence of Late Jurassic to Early Cretaceous sediments deposited in a north–south elongate forearc basin and sourced from a andesitic volcanic arc.
