The Petrology and Geochemistry of the Yerington Batholith and the Ann-Mason Porphyry Copper Deposit, Western Nevada

Book Description
Field, petrologic, and geochemical data presented herein constrain the origin of porphyry copper mineralization in the Jurassic Yerington batholith. The batholith, with 58-68% SiO2, Peacock index 56, high K2O (3.0 wt% at 60% SiO2), high strontium (1100 ppm), and low initial strontium isotopic composition (0.7040), is similar to high-K orogenic andesites. Three major units were emplaced, from oldest to youngest: granodiorite, quartz monzonite, and porphyritic quartz monzonite (PQM), including porphyry. They show progressive decrease in volume, increase in depth of roof emplacement (
Evolution of the Iron Mask Batholith and Its Associated Copper Mineralization

Book Description
The Iron Mask batholith is one of several large alkaline intrusions in the Intermontane Belt that contain porphyry copper deposits. At this time, Afton mine is the only major copper-gold producer located within the batholith. This bulletin is a synthesis of studies completed to date on the Iron Mask batholith and the Afton deposit. Emphasis is placed on geochemical and mineralogical aspects of the batholith and the copper-gold deposit, that shed light on their derivation and evolution. Through theoretical modelling with pertinent thermodynamic data, the unique superene alteration features of the Afton orebody are explained. Applications of the major findings of this study are briefly discussed with respect to other copper-gold occurrences in the batholith.
