... ratios (Ni/CO3, Ni/OH and H 2 O/Ni), showing that these three samples referred to as ‘zaratite’ are chemically distinct; they are actually close to either anhydrous zaratite (Ortegal), nullaginite (Tasmania) or gaspéite (Pennsylvania). The XRD patterns of the three samples only validate their low...

... in the contact ore, the pentlandite has been converted into a nickel-rich violarite, and the iron released by this reaction has participated in the conversion of some of the millerite to violarite. Decomposition of the sulfides at the water table has resulted in the formation of gaspeite and reevesite. GeoRef...

... gaspéite samples. Goldsmith & Northrop (1965) indicated a theoretical complete solid solution between spherocobaltite and magnesite at 600 °C and 15 kbar; this study is the first report of (Mg,Co)CO 3 in nature. The solid solutions of magnesite are better documented: magnesite has complete solid...

... and it was undersaturated with respect to both cal-cite (CaCO 3 ) and gaspeite (NiCO 3 ). XPS proved Ni adsorbed while AFM demonstrated that the surface was dissolving. Although this sounds inconsistent, it is logical from the perspective of the separate processes. Each is responding to its own drive to equilibrium...
