The Cajon Borate Deposit lies within Bacanora Minerals Ltd’s Magdalena Basin Project area in the state of Sonora, Northern Mexico. The Magdalena project consists of 2 concession blocks covering a total of 15,508 hectares. The concessions are 100% owned by Bacanora’s Mexican subsidiary: Minera Sonora Borax S.A. de C.V., subject to a 3% royalty to a Rio Tinto subsidiary and a 3% gross over-riding royalty to Colin Orr-Ewing. The property is road accessible and located 17 kilometres east of the town of Magdalena de Kino and has excellent access from that centre, either by rail or truck, to local markets for borate or to overseas markets from the port at Guaymas. <...>

Since the earliest days of NMR, it has been recognized that the technique can provide information on matters concerning the disposition of atoms in the unit cells of crystals. Thus, the distance between protons in the water molecules of gypsum, CaSO4 · 2H2O, was determined by Pake and reported as 1.58 A in 1948. However, the term NMR crystallography has only recently come into common usage, and even now causes raised eyebrows within some parts of the diffraction community. On the other hand, the power of solid-state NMR to give crystallographic information has considerably increased since the CPMAS suite of techniques was introduced in 1976.

This volume is the ninth of a series of review volumes published jointly under the banner of the Mineralogical Society of America and the Geochemical Society. The newly titled Reviews in Mineralogy and Geochemistry has been numbered contiguously with the previous series, Reviews in Mineralogy. <...>
