... of these processes is probably unknowable. The Nova orebody has systematically higher Ni and Cu tenors (relative ~30%) than Bollinger, particularly within the massive and semimassive ores. Palladium tenors in the Nova massive ores are likewise about 30% higher than at Bollinger, but the Pd tenors...

... is ABCDEEDCBA. The relation between structures of minerals with the common formula Pd 8 T 3 ( T = As or/and Sb) are discussed. They are formed by nets of pnictogen and palladium atoms. The common feature of the structures is 3 6 topology of pnictogen nets. The differences are stacking sequences and topology...

Naldrettite (Pd 2 Sb) is a platinum group mineral (PGM) almost exclusively composed of palladium...

... Palladium-dominant minerals generally fall into one of two categories: (1) intermetallics, where Pd is bound to chemically similar transition elements such as Cu, Fe, etc . (skaergaardite, PdCu; Rudashevsky et al . 2004 ) and where metallic bonding dominates, and (2) chalcogenides, including those bound...

MSS from the MSS-ISS matrix generally contains higher abundances of Co and Cu than those in MSS from the globules...

..., the free space in the tube was reduced by placing a closely fitting silica glass rod against the charge. A charge of about 250 mg was carefully weighed out from the native elements. For starting chemicals we used palladium powder (99.95% purity), indium pebbles (99.999% purity), and arsenic powder (99.9999...
