Exempel på hur man kan använda GLAUCONITE i en mening

• Gault often contains numerous phosphatic nodules, some thought to be coprolites, and may also contain sand as well as small grains of the mineral glauconite.
• Typically the shales do not contain many fossils, while the coarser sandstones often have fractions of micas and glauconite.
• The more striking additions to our knowledge included the detection and description of cosmic dust, which as fine rain slowly accumulates on the ocean floor; the development of zeolitic crystals on the sea-bottom at temperatures of 32 °F (0 °C) and under; and the distribution and mode of occurrence of manganese nodules and of phosphatic and glauconite deposits on the bed of the ocean.
• Molecap Greensand (Kcm) is a fine to medium grained marine glauconite sandstone which unconformably overlies the Osborne Formation.
• Iron reduction may impart greenish gray colors, though certain minerals including glauconite, melanterite, and celadonite can also give soil a green color.
• The glauconite per se will incorporate electrochemically bound water (CBW) because of the clay types.
• When fresh the rocks have a greenish colouration owing to the presence of glauconite, but on exposure to the atmosphere this is rapidly oxidised to limonite, giving rise to a yellow or reddish brown staining.
• When bioclasts are in its rock formation, meaning that they have gone through all the stages that sediments go through to reach its final phase, a whole rock unit, it is accompanied and mixed with variable amount of terrigenous material, glauconite particles and also phosphate grains.
• Frequently the crystals are replaced by diagenetic phases such as goethite, pyrite, glauconite, K-feldspars, quartz, sericite, chlorite, and carbonates.
• Saponite, talc, talc-saponite, nontronite, glauconite, and serpentine are all common on the seafloors on Earth.
• Saponite, talc, talc-saponite, nontronite, glauconite, and serpentine are all common on the seafloors on Earth.
• Spectroscopically, therefore, the analytical challenge is to differentiate between the green earths celadonite and glauconite, and perhaps chlorite, and the copper-containing malachite and verdigris, with the added ability to recognize the presence of haematite, Egyptian blue, calcite, dolomite, and carbon which have been added to change the colour tones.
• It is overlain disconformably by the Eocene Alka Formation glauconite sands, silts and phosphorite up to 27 meters thick.
• The focus of much of his scientific work was the determination of the crystallographic structures of phyllosilicates, such as dickite, vermiculite and glauconite, which he examined with an X-ray diffractometer he developed himself.
