| 1928 F. A. Bannister in Nature 1 Dec. 866/1 The name nahcolite is proposed for naturally occurring sodium bicarbonate. These incrustations were found lining the walls of a cuniculus near the Stufe di Nerone, Baia, Naples, Italy. 1929 ― in Min. Mag. XXII. 60 Dr. L. J. Spencer has very kindly suggested an ingenious name, Nahcolite. 1940 Amer. Mineralogist XXV. 777 The origin of nahcolite in the Stufe de [sic] Nerone and in a lava tunnel at Vesuvius can be easily explained by the action of CO2 and water vapor upon thermonatrite or trona. 1971 Prof. Papers U.S. Geol. Survey No. 750-b. 194 This report describes a new analytical technique for determining the amount of nahcolite in oil shale. |
