At Cap Blanc Nez (Channel coast, France), the chalk of Lower Cenomanian is very rich in glauconite. Glauconite authigenic origin and requires mobilization chemical elements for its growth: Si, Fe K. If we already know thanks to elementary geochemistry (Ge/Si ratio) that silica flint present originates from dissolution sponges, it same glauconite? This question only makes sense if glauconite pro...

The integrated use of minerals facilitates the reduction in impact mining on environment. Many industries are need quartz sand huge quantities. Quality requirements for often refer to a high percentage SiO2 and low content Fe2O3, as well absence clay impurities. extraction conditioned sands their close geographic location consumers economically profitable. Due wide distribution Ukraine subsurfa...

Glauconite is an authigenic clay mineral that common in marine sedimentary successions. Dating of glauconite to determine the depositional age sequences has a long history but fallen into disfavor due difficulty obtaining “pure” separates. Recent advances petrography and reaction cell mass spectrometry permit rapid situ Rb-Sr dating carefully screened grains. However, remains susceptible burial...

The results of a study on the use glauconite-containing overburden rocks Novodvorskoye deposit Pinsk district Brest region to produce glasses for various purposes are presented. compositions raw materials in system «glauconite-containing rock – chalk iron oxide soda ash» have been developed, limiting amount components and basic oxides optimized. It has established that main criterion obtaining ...

Glauconite (Gl), a naturally occurring clay material, was utilized as an affordable and ecologically friendly adsorbent to explore its capturing capacity towards Congo red (CR) dye from textile industrial waste effluent. To improve adsorption removal effectiveness, modification technique utilizing polyaniline (PAN) investigated. An X-ray diffractometer (XRD), scanning electron microscope (SEM),...

This work examines the possibility of a rapid formation glauconite in relatively shallow platform environment (below fair-weather wave baseline). The materials studied here are uppermost Jurassic alternations carbonate beds and marly interbeds, namely, Assises de Croï Formation Boulonnais area (northernmost France). yield field evidences an early diagenetic origin both interbeds contain glaucon...

The results on the research of heat-insulating porous ceramic materials produced using overburden rocks Novodvorsk deposit Pinsk district Brest region as main component raw are presented in study and use bulk rock consisting glauconite sands aleurites is recommended. Low-melting clay, basalt a blowing agent used additional components, rational combination which would ensure forming ability mass...

The impact spherules from the distal K–Pg boundary sections are considered to represent silicate droplets condensed and solidified from a laterally expanding, cooling vapor plume formed upon hypervelocity impact. In the present-day Cretaceous– Paleogene boundary (K–Pg) spherule population of the Umbria–Marche region in Italy, three texturally and compositionally distinct types of impact spherul...
