Cherty limestone

We focus on a well-constrained sample set from the Eocene North American Cordillera (Cherty Limestone Formation, Elko Basin, NV, United States, 42–43.5 Ma) on the east side of the elevated Nevadaplano. We present triple oxygen isotope measurements on freshwater lacustrine chert samples from the Cherty Limestone Formation. Across an ....

He correlated the upper member of the outcrops, which is a cherty dolomite, with some part of the Fern Glen limestone (of early Osagian age). The Chouteau restricted, or lower Chouteau, consists of light bluish-gray to dark-drab compact earthy to silty impure limestone banded with dull-gray chert nodules 1 to 4 inches thick.Nolans Limestone- upper and lower limestone separated by shale, 40 ft thick. Odell Shale- mostly red and green shale, 40 ft. thick. Winfield Limestone (base WF)- cherty limestone with fossiliferous gray shale, 25 ft. thick. Doyle Shale- two shale members separated limestone, 70 ft. thick.The nearly level to rolling Springfield Plateau is underlain by cherty limestone of the Mississippian Boone Formation and Burlington Limestone; it is less rugged and wooded than Ecoregions 38, 39b, and 39c, and lacks the Ordovician dolomite and limestone of Ecoregions 39c and 39d. Karst features, such as sinkholes and caves, are common. Cold ...

The chert-bearing limestone beds in the western part of the county underlie the Flint Hills Upland, a part of the Osage Plains. The Flint Hills escarpment, formed by the chert-bearing limestone beds, bi­ furcates; one branch follows the Big Blue River and the other follows the Nemaha range in the eastern part of the county. The Kansan glacier covered all but the …Abstract. It is proposed that many nodular cherts in limestone have formed in the ground water of mixed meteoric-marine coastal systems where dissolution of biogenic opal and mixing of marine and fresh waters can produce waters highly supersaturated with respect to quartz and undersaturated with respect to calcite and aragonite. Sw forms the highest Silurian unit throughout most of its extent, generally overlain by Dw; locally interfingers with Sh dolomite strata to south. Primary lithology: limestone, dense, fossiliferous. Secondary lithologies: limestone, dense, cherty to very cherty; dolomitic limestone, dense; dolomite (locally at base).This paper is concerned with the stratigraphic succes-sion of the uppermost Permian, Triassic, and basal Jurassic in the NKT, introducing refinements of previous interpre-75) for its type exposure on Liston Creek in southwestern Wabash County, Ind.

It is described in the statute as “a chalcedony pseudomorph after coral, appearing as limestone geodes lined with botryoidal agate or quartz crystals and drusy quartz fingers, indigenous to Florida.” See below to discover the rocks and minerals of Florida.
