Copies of published information have been cataloged and is included in a categorized bibliography . This was done for the Precambrian to Holocene. All events have not been charted but most of the events that affect the area surrounding the MSB and in the basin are included. This was done by literature work then reinterpreting and integrating the data as required. Can this methodology be used in other basins for determination of additional trapping mechanisms and evolution of structure.
Subregional maps are at county level in order to get a a more specific definition of location.
From this work on the maps and literature a premise has emerged under which assumptions have been made. A main period of complex activity was the late Cretaceous. These resultant configurations are conceptual but models have been built that can account for today's structural features. This quite probably had an effect on the type of subsequent movement.
