1914Larsen & Hicks in Jrnl. Washington Acad. Sci. IV. 397 The mineral for which the name searlesite is proposed was found in samples from the deep well in Searles Lake, San Bernardino County, California. 1950Amer. Mineralogist XXXV. 1017 In the stratum of trona 10 feet thick that is reached by the shaft at a depth of 1500 feet, subhedral crystals of searlesite up to 7 inches long, 4 inches wide, and one inch thick are not uncommon. 1974Mineral. Abstr. XXV. 303/1 The phyllosilicate searlesite, Na2B2(OH)4Si4O10, has been made from mixtures of Na2O, B2O3, SiO2 and excess H2O heated under steam pressure at 250°C for up to 8 days. |
