Limestones enriched in phosphate by the chemical action of ocean waters constitute a principal source of raw materials for the fertilizer industry. When heated to temperatures of 900 to 1,000 °C (1,650 to 1,800 °F), limestones will dissociate calcium carbonate and yield carbon dioxide and lime, the latter having major applications in the Phosphate sorption by jurassic oolitic limestones ScienceDirect Sorption isotherms and calcium phosphate solubility data were used to interpret the processes responsible for sorption of phosphate on three Jurassic oolitic li. 1975-4-1 Phosphate appears to be bonded less strongly (k" ~ 0.05 m/#g P) on the low-energy adsorption sites of limestone LM 70 than on comparable sites (k" = 0.08--0.45 ml/~g P) on calcium carbonate present in soils derived from Jurassic limestones (unpublished data). 2010-7-1 The total mass of PO 4 3 input to the limestone in the first phase of the experiments was 1676 μmoles (Table 1). The amount of PO 4 3 desorbed from the limestone ranged from 3 to 25 μmoles upon flushing with blank DIW. The limestone retained 1235 μmoles of PO 4 3 or about 75% of the input PO 4 3 during phase I. 3.2. Phosphate minerals occur in most members of the Lexington Limestone, principally the Tanglewood, Millersburg, and Grier Limestone, and parts of the Lexington which were mined in the early 1900's. Although commonly called collophane, the phosphates are the high-tatric Albian condensed limestones (Tatra Mts). Their origin is due to accretional growth and intraformational reworking. They were slowly growing by accretion of colloidal phosphates, in form of a homogeneus mass with some microglobuies (supposedly phosphate-enriched microorganisms), and 2020-9-25 Cave phosphate deposits derived from bat droppings are of more interest for the unusual minerals they may contain than for their economic value. Such deposits are mostly in consists of tabular, fine-grained limestones;10–15 cm thick, de-void of hummocky cross-stratification or other cross-lamination, suggesting deposition below fair-weather wave base. Some beds 2021-2-11 Limestone also has considerable commercial importance. Limestones enriched in phosphate by the chemical action of ocean waters constitute a principal source of raw materials for the fertilizer industry. The phosphate mineral distribution as it relates to in situ soil solution composition of two Alfisols developed from phosphatic Ordovician limestones in the inner Bluegrass Region of
