olistostrome

The interpretation of the mélange is that it is either an olistostrome or an upwelling.

The Buttermere Formation is interpreted as an olistostrome.

On the south an olistostrome, the remains of a landslip from the Gorringe Bank, resulting in chaotic sediments.

Nappe overthrusting and deformation of the foreland followed before the olistostrome sediments had lithified.

This is an olistostrome of disrupted sheared and folded mudstone, siltstone and sandstone.

On the northern flanks are outcrops of the Buttermere Formation, olistostrome of disrupted sheared mudstone, siltstone and sandstone.

Low Bank lies across the Causey Pike Fault and is part of the Buttermere Formation, an olistostrome of disrupted sheared and folded mudstone, siltstone and sandstone.

The structure and scale of the olistostrome is interpreted as intense faulting and rifting, supported by topographic relief represented by deep incision of overlying arenites (the Corboy Formation) into underlying units.
