Summary
[edit]DescriptionChalk & impure chalk (Smoky Hill Chalk Member, Niobrara Formation, Upper Cretaceous; Monument Rocks, Kansas, USA) 1.jpg |
English: Chalk & impure chalk in the Cretaceous of Kansas, USA.
This western Kansas landscape consists of chalk badlands and chalk pillars. The rocks are chalks and impure chalks (e.g., argillaceous chalk and chalky shale) that range in color from whitish to light gray to yellowish. Chalk is a biogenic, calcitic, marine sedimentary rock composed of numerous coccolith microfossils (see: www.soes.soton.ac.uk/staff/tt/eh/pics/lith2.gif). Coccoliths are individual calcareous plates that covered a single-celled photosynthetic marine organism called a coccolithophorid (a.k.a. coccolithophore) (see: upload.wikimedia.org/wikipedia/commons/d/d9/Emiliania_hux...). Stratigraphy: Smoky Hill Chalk Member (a.k.a. Smoky Hills Member), Niobrara Formation, mid-Upper Cretaceous Locality: Monument Rocks (also known as the Chalk Pyramids), along Gove County Road 16, north of the Smoky Hill River, Gove County, western Kansas, USA (38° 47' 43.24" North latitude, 100° 45' 52.06" West longitude) |
