The least common were inclusions of platiniridium and platinosmiridium; zoning
was not a significant factor in the composition and very few intergrowths were
observed. Some platiniridium was found as exsolution features in platinum laths.

The loop may be made of platinum wire, but platiniridium has the advantage of
being stiffer, and a cheaper material such as Nichrome will often serve the
purpose. The width of the gap should be adjusted as follows: Hold the loop
horizontal, ...

NEW ZEALAND Osmiridium was discovered in New Zealand in 1860. Platinum
and platiniridium are also known to occur, and Morgan (1927, p. 76, 77, and 81-

This, however, was based on the mistaken assumption that platiniridium
inclusions in Pactolus gold made it readily distinguishable from that of other
sources (Muhly 1981:146, 1983:1-14; Moorey 1985:74-5), and that the presence
of such ...
