Summary. Silurian pinnacle reefs have remained the main exploration targets in the Michigan basin over the last decade. Recent discoveries have extended the reef belt into new areas in the western and northeastern parts of Michigan's lower penin. The controversial issue as to whether or not certain structures in the Niagaran of the Great Lakes region are true reefs is reviewed.
Reefs are defined in terms of fundamental biologic potentials of the organisms responsible for them rather than in terms of the present-day appearance of the structures.
These potentials are the ability to erect rigid topographic structures by frame Cited by: While the reef core in the STF has a Brown Niagaran thickness of 90 m, over a lateral distance of km the overall thickness grades in the leeward direction (southwest) to a thickness of 75 m in the leeward proximal reef apron, 47 m in the leeward distal reef apron, and only 4 m in the leeward toe-of-slope.

Surface karstification and erosion of the Lockport and Peebles dolomites occurred prior to formation of the overlying Greenfield Dolomite. Subsurface karstification of Lockport/Peebles strata is interpreted to have occurred concomitantly with surface karstification of these units.
Climatic conditions during karstification were probably semi-arid. LOWENSTAM, H. A., a, Biostratigraphic studies of the Niagaran inter-reef formations in northeastern Illinois: Illinois State Museum Science Papers, v.

Based on the facies described and thicknesses from the DGR boreholes (Sterling and MelaneyINTERA ), the Bruce nuclear site is clearly represented by Niagaran inter-reef facies.

The search for hydrocarbon-bearing Silurian Niagaran pinnacle reefs commenced when exploration technology became sufficiently advanced to accurately locate areally small reefs. Starting ingravity methods were used to locate 90 reefs in southwest Ontario and southeast Michigan but, as the reef trend was pursued westward, gravity data.

Sandomierski3, and W.B. Harrison III1. The Niagaran Series has been intensively studied in the Michigan Basin subsurface since the first hydrocarbon reservoirs were discovered in reefs in Ontario in the s (Mantek, ).
Exploration of the reef trend expanded into southeastern Michigan in the s, and into northern Michigan, south-central Michigan and southwestern Michigan. Search the history of over billion web pages on the Internet.
The Michigan Basin has been the subject of several diagenetic studies in the last three decades (e.g., [1,2,3,4,5,6,7,8]).However, very few comprehensive investigations regarding the nature and composition of diagenetic fluids, lateral extent of the diagenetic processes and paragenetic sequence of different types of dolomite within Silurian and Devonian successions in the Huron .A depositional and diagenetic framework, developed for several Niagaran-Salina reef complex reservoirs in Michigan, facilitates spatial prediction of lithofacies in inter-well areas.
Fifteen distinct lithofacies are defined, each with comparable pore geometry, and preliminary results indicate that the individual facies have good correlation.An illustration of an open book. Books. An illustration of two cells of a film strip.
