Summary:

Pg. vii, 12, 93, 114-115. Roubidoux sandstone. Fossiliferous sandstones, overspreading Ozark region from Cabool to Gasconade City and from Salem to Doniphan, embracing much, if not all, of what has been called Second sandstone, and will undoubtedly include the areas of so-called First sandstone as well, which is believed to be same as Second sandstone. The Roubidoux is upper formation of Ozark series. Overlies Gasconade limestone, the lower formation of Ozark series. Age is Early Ordovician (Beekmantown).
Named from Roubidoux Creek, in Texas and Pulaski Cos., central MO.

Summary:

Pg. 47-50. Roubidoux formation. Interbedded sandstones and dolomites; variable in character; in some places is almost entirely sandstone; whereas in others it is mainly dolomite. Basal sandstone irregular in thickness, ranging from less than 1 foot up to 30 feet; color reddish-brown or sometimes gray. Thickness 160 to 170 feet.

Summary:

Roubidoux formation. As originally defined, Roubidoux did not have specific type section. Type section is herein designated. Thickness 150 feet at type section. Here formation overlies Gasconade and underlies Rich Fountain formation of Jefferson City group. May rest unconformably on Gasconade, but there is little field evidence to support this view; Roubidoux-Rich Fountain contact appears to be one of conformity. Systematic description of fauna. Age is Early Ordovician (early Canadian).
Type section: along southeast-facing hillside above Roubidoux Creek, in SE/4 NW/4 SW/4 sec. 10, T. 33 N., R. 12 W., Roby 7.5-min quadrangle, Texas Co., central MO. Widely distributed throughout most of Ozark uplift in MO.

Summary:

(Paleozoic Era; [Cambrian through Mississippian Systems] by E.D. Goebel, p. 13.) Roubidoux Formation. In Kansas, this formation consists mainly of sandy dolomite and fine-grained sandstone. Deposition of the Roubidoux seems to have been preceded by folding and erosion of older rocks. Thickness of the formation generally ranges from 150 to 200 feet.

Summary:

Roubidoux Formation is oldest outcropping rock in quadrangle. Occurs on Ozark dome in Missouri. In subsurface, sand content decreases eastward and it becomes difficult to distinguish from other formations. In subsurface of Illinois basin, equivalent sediments are assigned to Shakopee Dolomite. Age is Ordovician (Canadian).
