The oolitic character of the limestone, the type of chert and the abundance of glauconite in the dolomite, and the regional distribution of the rocks favor the correlation of (1) the cherty dolomite beds with the Keokuk and Burlington, (2) the oolitic limestone beds with the Gilmore City, and (3) the sandstone with the "Misener sand."McClellan indicated that the Arbuckle limestone on the Barton arch was mainly white, dolomitic, and characterized by oolitic chert and interbedded coarse sandstone. He used these characteristics in comparison with a similar zone in Oklahoma to suggest that, if the units were correlative, approximately 3,400 ft of upper Arbuckle limestone was ...

Mineral deposit - Iron Ore, Ore Bodies, Mining: By far the most important metal from an economic and technical point of view is iron. Sedimentary iron deposits, from which almost all iron is obtained, can therefore be viewed as one of the world’s great mineral treasures. There are two major types of deposit. The first, and by far the most important, is banded …

The Fort Payne Chert is a basin-filling sequence that onlapped the earlier prodeltaic sediments from the south and west. The oolitic and skeletal limestone of the lower portion of the Newman Limestone formed in the clearer and more turbulent water of the shallow-marine shelf formed on the Fort Payne Chert and the Grainger Formation.

Original language: English:A different form of limestone, known as oolitic limestone, can be found in the town of Oolitic, near Bedford. When it comes to finding chert in Indiana, there are eleven predominant types, dating back to the Silurian, Devonian, Mississippian, and even Pennsylvanian ages.Minor: oolitic dolomite and oolitic chert (Shakopee); shale, green, part sandy (Shakopee); shale, green-brown to gray, part laminated, silty to sandy, part fossiliferous (locally in St. Peter of Winneshiek Co.); coarse sand grains (St. Peter, Shakopee); breccia, dolomite-chert clasts; chalcedony/quartz nodules.The cherts are dark in color in the lower part of the sequence and light in the upper part. The quantity of chert varies considerably both vertically and horizontally. The sequence includes an oolite member (Short Creek Member) near the top of the Boone Formation in western exposures and the generally chert-free St. Joe Member at its base.

Banded iron formation (BIF) is a deep sea-floor deposit of iron oxide that is a common ore of iron (Figure 6.2. 6 ).
