Solid state interaction between dolomite and urea nitrate

Solid state interaction between dolomite and urea nitrate. Pathak, D. N. (Dep. Chem., Reg. Inst. Technol., Jamshedpur, India). Proc. Natl. Acad. Sci., India, Sect. A, 46(1), 73-5 (English) 1976. CODEN: PAIAA3. ISSN: 0369-8203. DOCUMENT TYPE: Journal CA Section: 19 (Fertilizers, Soils, and Plant Nutrition) A solid state interaction occurred when dolomite [16389-88-1] and urea nitrate [124-47-0] powders were ground together for 2-3 h. The product was water sol. when the wt. ratio of dolomite to urea nitrate was 1:3. The method may be utilized to manuf. a mixed fertilizer contg. water-sol. Ca and Mg and a relatively less sol. source of N suitable for regulating the nutrient supply to plants.

Petrologic and geochemical constraints on the origin of subsurface dolomite, Enewetak Atoll: an example of dolomitization by normal seawater. Saller, Arthur H. (Dep. Geol., Louisiana State Univ., Baton Rouge, LA 70803, USA). Geology, 12(4), 217-20 (English) 1984. CODEN: GLGYBA. ISSN: 0091-7613. DOCUMENT TYPE: Journal CA Section: 53 (Mineralogical and Geological Chemistry) Dolomite [16389-88-1] in Eoceme strata of Enewetak Atoll has a 87Sr/86Sr ratio of 0.70865-0.70901, indicating formation between mid-Miocene and the present. The O-isotopic ratios of dolomite samples suggest that they formed in cold seawater. The deep dolomite pptd. from cold, deep ocean water which was undersatd. with respect to calcite, at a burial depth of >900 m, in permeable carbonate strata.
