... represents the upper auriferous alteration in the alkalic porphyry Au-Cu system. Alteration mineral assemblage, S isotope (ranging from δ 34 S –5‰ relative to Canon Diablo Troilite in the core to δ 34 S +0.5‰ in the periphery), and limited fluid inclusion data suggest mineralization at the Au-Cu alkalic...

... to differentiate it from pyrrhotite, so the Del Norte troilite is an important discovery, not alone on account of its terrestrial origin but also because of its abundance. It agrees with the troilite of the Cañon Diablo meteorite in its properties, pieces of which were kindly given to me by Mr. Merrill, so the two...
