...D. W. Kohls; J. L. Rodda Abstract A new nickel carbonate mineral was found as a vein enclosed in siliceous dolomite in the Gaspé Peninsula, Quebec. Magnesium and to a lesser extent, iron, carbonates are in solid solution with the nickel carbonate. The name gaspeite has been selected for the nickel...

... 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...
