Oolite is a sedimentary rock made up of ooids (ooliths) that are cemented together. Most oolites are limestones — ooids are made of calcium carbonate (minerals aragonite or calcite). Ooids are spheroidal grains with a nucleus and mineral cortex accreted around it which increases in sphericity with distance from the nucleus.Minor: chert and chalcedony nodules (Pinicon Ridge Fm); sandstone; oolitic limestone (Otis Fm). Extensive anhydrite/gypsum in subsurface outside of outcrop belt. Maximum thicknesses in outcrop belt: east-central Iowa, 60-160 ft (18-49 m); northern Iowa, 10-130 ft (3-40 m), locally absent in Bremer County beneath Dc.

o·o·lite (ō′ə-līt′) n. A sedimentary rock, usually limestone, consisting of ooliths that are cemented together. o′o·lit′ic (-lĭt′ĭk) adj. American Heritage ... Very fine (chert-like) silcretes and oolitic chert (only available in very small amounts) were used preferentially for making retouched artefacts. These findings can be extrapolated to a more extensive desert landscape stretching from Port Augusta in the south to Lake Eyre in the north. Original language: English:The oolites have been preferentially weathered and eroded, resulting in secondary oolitic porosity in the chert. Vanport Flint (10.5 mm across) (above & below) - fusulinid foraminifera in flint. Fusulinids are one of several groups of fossils observed in the Vanport Flint at Flint Ridge, Ohio.

Much of the chert found in float is light gray, cream, tan, and white. The chert is commonly deeply weathered with black stains and contains rhombohedral shaped molds of weathered dolomite crystals.we offer 18 pounds of oolitic chert, very good grade, would make 2" sps, or really nice cabs. Excellent preservation, excellent silification.

Take this with several grains of salt; I'm not an expert! Hard to tell. Your photos are rather blurry--I'd recommend re-taking them in a stronger light. That said, this could be chert with a layer of white chalk containing quartz grains. It doesn't quite look oolitic to me (but a better photo might change my opinion).CHERT is used in this analysis in its usual archaelogi­ cal context and distinct from its more correct petrological meaning as a form of chalcedony. In the analysis of refuse material, chert was divided into two major categories: oolitic and non-oolitic chert. Oolites, as …Wamsutter Oolitic Chert AKA: Green River Oolitic Chert: Ranges from an off white to a medium brown with white oolitic specks throughout the material: Northwestern Colorado: Green River Formation: White River Group Silicate Generic type : Ranges from light to medium gray, to a light brown, pink, blue or lavender with inclusions, splotches, mottling.

It is mostly composed of iron, aluminum, titanium, and manganese oxides because these are the least soluble components of the rocks undergoing a type of chemical weathering known as laterization or lateritization.
