...Federico Ortí; Laura Rosell; Javier García-Veigas; Cahít Helvaci Abstract: Probertite and glauberite are the main rock-forming minerals in the lacustrine Doğanlar succession of the Emet basin. The present paper seeks to characterize and interpret the facies and depositional settings of this mineral...

...Joan R. Clark; C. L. Christ Abstract Ulexite and probertite crystals have been examined by x -ray precession methods and earlier findings confirmed. Revised data for the crystallographic elements are as follows: ulexite, NaCaB 5 O 9 · 8H 2 O, triclinic P 1 –C i 1 , a = 8.80 9 ±0.02, b = 12.86±0.04...

...William H. Barnes Abstract In a recent paper on “The Unit Cell and Space Group of Probertite” ( Am. Mineral., 34 , 19-25 (1949)), at the bottom of p. 23 and the top of p. 24, Ft c * and Ft a * are shown equal to Fd c * and Fd a * , respectively. Since probertite is monoclinic, this is, of course...

...William H. Barnes Abstract The unit cell constants and the space group of probertite, Na 2 O · 2CaO · 5B 2 O 3 · 10H 2 O, have been determined by the Buerger precession method with the following results: a = 13.88 Å b = 12.56 Å c = 6.609 Å β = 107°40'; a : b : c = 1.1053:1:0.5263; Z =2; calculated...

...Joseph Murdoch Abstract A small specimen sent the writer recently, marked “Lang Borax Mine,” proved on examination to be probertite. Since this mineral has been reported only from the Ryan and Kramer districts, in California, advantage was taken of a class field trip to the Lang area, where a good...

...William F. Foshag Abstract The mineral probertite was described by A. S. Eakle 2 as a new hydrous borate of soda and lime from the borax mines near Kramer, California. The mineral was independently described by Waldemar T. Schaller 3 under the name kramerite. At this locality it is one of the minor...

...Arthur S. Eakle Abstract The new borate described in this paper occurs as one of the minerals of the kernite deposit 1 in the Kramer District, Kern County, California, and the name “probertite” is proposed for the mineral, in honor of Frank H. Probert, Dean of the Mining College, University...

... and/or probertite) inner zone (or zones) surrounded by Ca borate (colemanite). The remaining deposits consist essentially of colemanite. Investigators have debated the origin of the mineralogical zoning and the relationship, if any, between the zoned and colemanite-only deposits. The Ca and Na-Ca borate zoning has...
