U.S. Geological Survey professional paper
The platinum is always accompanied by small quantities of iridosmine and
probably also iridium. Bright scales of iridosmine are locally present in
considerable quantities. Though of widespread occurrence platinum is not
recovered on a ...

Geological Survey Professional Paper
Rounded grains of pyrite, quartz, iridosmine, and other minerals are engulfed by
strands of carbon, and this feature accounts for a typical augen texture, with gold
and reconstituted sulfides accumulated in the pressure shadows on either side ...

The table of analyses brings out very clearly the fact that platinum isextremely
subordinate in iridosmine, and may entirely fail. It varies from nothing through a
general amount of leas than 1 to 10.08 in No. 8, a Russian sample, as a
maximum.

In 1831, James Prinsep proved that a button of white metal, which had been sent
to the Asiatic Society of Bengal, was an alloy containing 25 per cent of platinum

The grains examined are composed essentially of three primary phases which,
for present purposes, may be designated as iridosmine I, iridosmine II, and osmiri
- dium. A rough micrometric analysis has shown that iridosmine II and osmiridium
