A Study Of The Subsurface Stratigraphy Of The Upper Cambrian In Western Missouri, Joseph L. Thacker Jr.
Masters Theses
"Megascopic examination of diamond-drill cores supplemented by insoluble residue data provides a usable means of studying the lithologic characteristic of Upper Cambrian strata in the subsurface of western Missouri.
The stratigraphic relationships within each Cambrian formation and the relationships of each Cambrian unit to formations above and below are discussed.
The relationship of Upper Cambrian strata to the Precambrian surface in western Missouri and easternmost Kansas is illustrated. The Lamotte Sandstone is overlapped by the Reagan Sandstone against Precambrian topographic highs and the Bonneterre and lower Davis are replaced by sandstones similar to the Reagan in southwest Missouri and southeast …
