erystals with chlorite and iron pyrites on granite (C.). 
PIMELITE—Cobalt lode, Kilkivan !, earthy variety (R.). 
PratinumM—Russell River Terraces !, iinute flakes associated 
with gold and cassiterite in high-level river drifts capped 
by immense basaltic flaws, probably miocene (J.). 
PREHNITE—Biralee, Bowen River ! !, in cavities in epidote rock, 
“in radiating groups of crystals” (Allport),—{ Analysis

Pyritres—Bee Creek, 60 miles west of Mackay ! !, as crystals in 
most of the mines, generally enclosed in a quartzose 
matrix, associated with galena, zinc blende and copper 
pyrites (M.); Allendale Lode, Chowey Creek, Wide

quantity of chalcopyrite and galena, assays 240z. gold 
per ton (L.), iron pyrites occurs probably without 
exception in all the auriferous reefs in Queensland, 
in most of the metalliferous lodes, disseminated 
through most of the plutonic and igneous rocks, in 
many sedimentary rocks, and conspicuously in the 
carbonaceous shales which form the country rock of 
the Gympie goldfield (J.).
