Our finding of magmatic PGE-base metal sulfide at Rathbun Lake suggests a new subtype of distal offset dike-hosted mineralization in an area so far not known for offset dikes. The timing and nature of this hydrothermal overprint remains uncertain, but a connection to later regional metamorphism and faulting seems most plausible. Micron-scale X-ray mapping revealed a progressive replacement of magmatic Pd-Bi-Te minerals, where in contact with hydrous silicates, by Sb- and Hg-bearing Pd minerals such as temagamite, Pd 3HgTe 3. In contrast to base metal sulfides, most precious metal minerals were resistant to hydrothermal alteration, although corrosion of some grains is noted as well as their truncation by chlorite and epidote. In its familiar compounds nickel is bivalent (molecule has a valence of two), although it assumes other.
It is of the iron-cobalt group and it takes on a high polish. ANickel is silvery white, hard, malleable, ductile metal, which is somewhat ferromagnetic, and a fair conductor of heat and electricity. This involved also local remobilization into pyrite-chalcopyrite veinlets and the liberation of precious metal minerals from their sulfide hosts. Nickel Ni (Element 28) of Periodic Table. The magmatic paragenesis was hydrothermally overprinted at lower greenschist-facies conditions to pyrite-chalcopyrite-violarite ± covellite ± millerite. For example, to insert a 1D array as the fourth row of a 2D array, wire 3 to the first index. This input can be an n-dimension array of any type.: index 0.n-1 specifies the point in the array at which you want to insert the element, row, column, page, and so on. By analogy with these footwall deposits, the occurrence is interpreted as having formed by downward percolation of a highly fractionated sulfide melt toward the bottom of a now largely eroded offset dike. n-dim array is the array in which you want to insert an element, row, column, page, and so on. Mineralogy, ore textures, and mantle-normalized PGE + Au patterns match a specific type of Cu-rich mineralization in the Sudbury Igneous Complex known as footwall mineralization. However, only those dikes proximal (0.9 and a Pd/Ir of >100,000. It is a hard, malleable, silvery-white metal. The origin of the name comes from the German word kupfernickel meaning Devils copper or St Nicholass (Old Nicks) copper. Quartz dioritic impact melt dikes around the 1.85 Ga Sudbury Igneous Complex, locally referred to as offset dikes, are well endowed with respect to Ni-Cu-platinum group elements (PGE). Nickel was discovered by Axel Fredrik Cronstedt (SE) in 1751.
