Summary:
Pg. 21-26. Bonneterre limestone. As a rule consists of more or less heavily bedded, granular, and highly magnesium limestones, generally compactly crystalline and often minutely vesicular, with dolomite crystals lining the cavities; a few beds are fine-grained; color light- or dark-gray; usually weathers yellowish; locally contains beds of a pink or more decidedly red color; chert and drusy quartz seem to be entirely absent; some beds, especially in lower part, contain much chlorite, in places sufficient to give them a decidedly green color; toward base much silica occurs as grains of sand in the limestone. Thickness varies from 200 to 250 feet in vicinity of Mine La Motte and Frederickstown to nearly 500 feet in St. Francois County, to the north. It seems to wedge out on old hillsides. Appears to grade into underlying La Motte [Lamotte] sandstone. Where top of Bonneterre has suffered least from widespread erosion that took place prior to deposition of Elvins formation, it grades upward from the massive limestones into a thinly bedded zone, and this finally into a bed of blue shale; locally the thinly bedded and shaly zones appear to be absent.

Summary:
Bonneterre formation. Consists of (descending): (1) argillaceous dolomite; (2) 250 to 300 feet of dark and light-gray dolomite with thin shale partings; (3) 50 to 100 feet of buff or gray dolomite, arenaceous buff or yellowish dolomite, thin green, gray, or brownish black shale beds, chloritic dolomite. Grades into underlying La Motte [Lamotte] sandstone. Is overlain by Davis formation (lower part of Elvins formation of Ulrich [and Bain, 1905, USGS Bull. 260]), 150 to 190 feet thick.

Overview

Summary:
Pg. 39. Nason placed upper limit of Bonneterre at edgewise conglomerate horizon, which is about 6 feet below "Central" marble boulder member of Davis formation. From sections given by Ulrich in 1905 it would appear that he similarly revised the Bonneterre, as defined by Nason, his Elvins formation being above the conglomerate, just below the "Central" marble boulder member of Buckley's Davis. Therefore Davis formation as recognized in latest reports contains probably 100 feet or more of shale and shaly dolomite that had been included in Bonneterre in earlier reports.

Summary:
Formation varies in thickness throughout area, for it overlaps Lamotte sandstone and is to a certain degree still affected by irregularities in Precambrian surface. Average thickness 375 feet; maximum thickness 448 feet of Delassus on Bonneterre plain. Thickness decreases regularly southward with average of 200 feet in Madison County and minimum of 50 feet where unit lies directly on rhyolite porphyry. Two-fold lithic division recognized: basal 50 feet, which is intricate sequence interbedded and intergrading glauconitic sandstones, fine gray and yellow shales, fossiliferous crystalline limestone, and barren white or pink dolomites; and a 200- to 300-foot upper part, which is essentially a massive-bedded barren crystalline dolomite. Basal 50 feet carries late CEDARIA fauna of more than 61 species. [Age is Late Cambrian.]

Overview

Summary:
Pg. 12. Bonneterre Dolomite. The Bonneterre is a conspicuously glauconitic, noncherty dolomite which is dark, gray to brown and finely crystalline in eastern Kansas and buff to white and coarsely crystalline in western Kansas. It includes sandy and silty dolomite, and, locally near the top, dolomitic shale beds. The Bonneterre is distributed throughout Kansas except in places on the Central Kansas uplift and the Nemaha anticline. In western Kansas, most of the rocks reported to be Arbuckle are probably equivalent to the Bonneterre (Merriam, 1963) [D.F. Merriam, 1963, "The geologic history of Kansas," Kansas Geol. Survey Bull., no. 162]. The Bonneterre is gradational downward into the Lamotte Sandstone. The thickness ranges from 0 at the margins of some uplifts to 150 feet in basin areas. [Age is Late Cambrian.]

Revised Areal limits	Ozark uplift

Summary:
Upper part of Bonneterre Formation revised in Crawford County, Missouri, southwest to Carroll County, Arkansas, within the Ozark uplift to include (ascending): Sullivan Siltstone Member (new) and Whetstone Creek Member (new). Has fairly uniform thickness eastward of Wright County, Missouri. Westward from Wright County to Taney County, Missouri, Bonneterre carbonates thin. West of Taney County, in Carroll County, Arkansas, all but the uppermost part of Bonneterre abruptly changes facies to a nearshore, coarsely clastic, sandy section which is assigned to the Reagan Sandstone. Basal unit of Bonneterre is Bonneterre-Lamotte "transition" beds. These beds are dominated by sandstone, contain varying amounts of dolomite, and are distinguished from underlying Lamotte Sandstone by addition of shale. Overlying "transition" beds are an intertonguing oolite facies and micrite and shale facies. One or the other of the two facies are in sharp contact with overlying Sullivan Siltstone Member (new) which, in turn, is overlain by Whetstone Creek Member (new). Whetstone Creek, uppermost unit of Bonneterre, underlies, in places unconformably, Davis Formation. High shale content in Davis distinguishes it from underlying Whetstone Creek. Age is Late Cambrian (early Dresbachian to early Franconian). Report includes Bonneterre Formation in core descriptions, cross section, stratigraphic chart.

Overview

Summary:
Pg. 18-19. The Bonneterre Formation. Is typically a light-gray, medium- to finely crystalline, medium-bedded dolomite, but also consists of pure limestone in some areas. In places it is very coarsely crystalline, it contains small cavities which are lined with dolomite rhombs. Locally, parts of the Bonneterre are glauconitic and shaly with the shale occurring in beds less than 2 inches thick. In some areas, the formation contains beds of relatively pure, thin-bedded, pink limestone which is referred to as "Taum Sauk marble." Wherever the Bonneterre has been deposited near or directly on the Precambrian surface, it contains pebbles and cobbles of igneous rock, much of which is felsite. Host rock at Doe Run's Hayden Creek mine is a granite conglomerate cemented by dolomite. Ore is present in dolomite and fills fractures in the granite boulders. Conformably overlies Lamotte Sandstone. The lower part of the Bonneterre consists of alternating beds of dolomite and arenaceous dolomite with the amount of sand increasing toward the base. This sandy zone (often called the "Bonneterre-Lamotte transition zone") is usually 10 to 20 feet thick, but may approach a thickness of 200 feet. The Bonneterre overlaps the underlying Lamotte on flanks of Precambrian highs. Westward, it [grades laterally into] nearshore facies of Reagan Sandstone. Includes Sullivan Siltstone and Whetstone Creek Members of Kurtz and others (1975, Missouri Geol. Survey, Rpt. of Inv., no. 55, p. 13). Most of the Bonneterre exposures lie to the north and east of the main area of Precambrian exposures; is concealed by younger beds to the west and south. In the Lead Belt and Viburnum Trend area, the formation is approx. 375 to 400 feet thick. Occurs in subsurface throughout most of state; attains maximum known thickness of 1,580 feet in subsurface of Peniscot County, Missouri. Major lead production has been from the lower half of the formation.

Summary:
Pg. 37. Nason's failure to designate which edgewise conglomerate was the top of his Bonneterre left the top of the formation uncertain. Buckley (1909, p. 26-44) was the first to establish the top of the Bonneterre as now defined. Overlies [Lamotte] Sandstone; underlies Davis Formation. Is equivalent to portions of the "St. Joseph limestone" of Winslow, the "Fredericktown limestone" of Keyes, the "Third Magnesian limestone" of Swallow, and the "Decaturville" of Shepard. Age is Cambrian. Report includes nomenclature history.
Type section: Nason (1901, p. 396) was the first to use the name Bonneterre. He applied it to the beds between what is now called the LaMotte Sandstone and an edgewise conglomerate in what is now called the Davis Formation. It was named from exposures at Bonne Terre, St. Francois Co., MO.
