In summary, the Jupiter-Chicotte formational boundary represents a disconformable
stratigraphic surface with a significant depositional facies offset due to a forced regression.
of the Schulz Ranch Member above a disconformable
contact with the underlying Holz Shale Member of the Ladd Formation.
The contact with the underlying Mississinewa Shale is sharp and disconformable
(Cummings & Shock 1928), but Pinsak & Shaver (1964) report lacking proofs for either disconformity or conformity.
The abrupt lithological change suggests that the Mosquito Lake Road/Matthews Lake Formation contact is disconformable
1990), longitudinal E-W dunes shaped by wind processes, and weakly developed NNW-SSE ridges that are remnant features of the strand lines above the disconformable
overlap of middle Llandovery dolomites by late Llandovery limestones also indicates dolomitization in the middle Llandovery or during the denudation at the end of the middle Llandovery.
This is one of the very few areas where the disconformable
contact between the 'Cadomian Basement Complex' (Goncuoglu 1997; Goncuoglu et al.
However, the abrupt change in lithology suggests a disconformable
rather than conformable relationship.
