The carbonate of ammonia was dissolved in water and sprinkled over the growing wheat at three different times during the spring. The carbonate which is formed upon the charcoal, beyond the oxide, is of a bluish-white color. The principal mineral impurities of well and spring water are lime, magnesia, soda, and oxide of iron, combined with carbonic and sulphuric acids, forming carbonates, sulphates, and chloride of sodium, or common salt. With carbonate of soda it fuses with effervescence to a bead which spreads over the charcoal. Examples of carbonatecarbonate She takes the broadest of views, including any discrete carbonate structure with topographic relief formed by in situ or bound organic components. There is also a general lack of seismic reflection horizons as a result of the uniformity of the carbonate succession. They are attached to the vein walls and embedded in carbonates just like the carbonaceous filaments. These fluids emanate from gigantic carbonate edifices that can reach 60m in height. Syn-kinematic, en-echelon tension gaps were filled by carbonate material. Possibly existing carbonates will form sulphates at their surfaces. We present a record of carbonate-associated trace sulfate concentrations over the same time period. The sabkhas are covered by a salt crust, 3-5 cm thick, under which there lies 25-150 cm of carbonate sand, gypsum and halite. The second geological outcrop was partly covered by a crust of sulphate and carbonate minerals. Ichnofossils and ichnofabrics in rhythmically bedded pelagic/hemi-pelagic carbonates: recognition and evaluation of benthic redox and scour cycles. Low-temperature, fine-grained, alteration products include serpentine, talc, bowlingite, white mica, epidote s. l., carbonate and opaques. Higher up in the sedimentary record, calcite becomes the most prominent carbonate mineral. Furthermore, volcanism coincided with prominent changes in local basin development, following collapse of the carbonate platform in this foreland basin. True thickness of the carbonate deposits is unknown due to folding, but it certainly was in the order of hundreds of metres or more. Occasional interbeds of fine-grained carbonate may reflect gravity input of peri-platform ooze, rather than sea-floor preservation of calcium carbonate.
