red beds, conglomerates and salt were considered azoic and problematic rocks, but paleopalynology and inorganic geochemistry proved to be useful for placing them in time and space. in the early last century, in mexican ne region, only three mesozoic red bed units were differentiated, dated as late triassic to late jurassic. it was important tratigraphically to place them properly as they were c...

We formally name the Sewell Point and Atlantic City Formations, two distinct Oligocene lithologic units identified in subsurface strata in New Jersey. These formations are stratotypified at the Ocean Drilling Program Leg 150X Atlantic City and Cape May boreholes. The lower to upper Oligocene Sewell Point Formation consists of glauconitic clays and silts and clayey glauconite sand. It can be dif...

Aim . The aim of research is to determine the suitability and fertilizing value fertilizers‐ameliorant, as well assess degree their contamination with heavy metals; approbation fertilizers‐ameliorants in various conditions cultivation agricultural crops. Material Methodology main agrochemical parameters sewage sludge chemical composition glauconite were studied by analytical methods laboratory ...

-Well-characterized American Petroleum Institute clay standards, source clays from The Clay Minerals Society, and other secondary minerals were used to determine the effects of U concentration, temperature, and solution composition on U-sorption properties. Uranium concentrations ranged from about 1.00 x 10 -4 M to 4.00 x 10 7 M, temperatures from 5 ~ to 65~ and solution compositions containing...

Abstract In the Alpstein massif of north-eastern Switzerland, a complete succession uppermost Hauterivian to Barremian condensed hemipelagic sediments crops out. This is known as Tierwis Formation, comprising in ascending order, Altmann and Drusberg members. The sedimentary bears number fossiliferous glauconite- or phosphate-rich beds. A large newly discovered ammonites from these key beds seve...

The Eridania region in the southern highlands of Mars once contained a vast inland sea with a volume of water greater than that of all other Martian lakes combined. Here we show that the most ancient materials within Eridania are thick (>400 m), massive (not bedded), mottled deposits containing saponite, talc-saponite, Fe-rich mica (for example, glauconite-nontronite), Fe- and Mg-serpentine, Mg...
