... to the Precambrian and Lower Cambrian rocks of the Blue Ridge province on strike with the Talladega belt to the northeast. In the Borden Springs area, Cleburne County, Alabama, nappes of the Lower Cambrian Weisner and Shady Formations rest on younger Paleozoic rocks immediately northwest of the Talladega belt...

...Woodward W. Fischer; Andrew H. Knoll Abstract Iron formations are typically thinly bedded or laminated sedimentary rocks containing 15% or more of iron and a large proportion of silica (commonly >40%). In the ca. 2590–2460 Ma Campbellrand-Kuruman Complex, Transvaal Supergroup, South Africa, iron...

... of “original” dolomite by the diagenetic decomposition of authigenic biotite mica accounts for production of dolomites of widespread formational extent. This theory provides a source of magnesium for the conversion of marine limestones to dolomites, and accounts for the presence of glauconite in sub-Trenton...

... with Cambrian rocks of the adjacent foreland thrust belt. The basal cover unit of each massif, the Pinelog Formation, is likely correlative with the Late Proterozoic Snowbird Group of the Ocoee Supergroup. This sequence was deposited in fluvial-alluvial to shallow-water deltaic to intertidal environments...

This 90-ft (27 m) glauconitic interval averages about 150 API units on the gamma-ray log. Rodgers (1967 , p. 409) wrote, “A wide belt along...
