The White Mountain granitoid suite represents an isolated window into Cretaceous age magma intruded into Wrangellia terrane basement. Although the total area of exposed granitoid at White Mountain is relatively small (∼1 km2), substantial textural, chemical, and isotopic complexities exist. The granitoid suite consists of six surficially isolated bodies, all of which are calc-alkaline and metaluminous, ranging in composition from hornblendebiotite quartz diorite to biotite granodiorite. Three 40Ar/39Ar analyses provide cooling ages between 113.3 ± 1.3 and 117.38 ± 0.54 Ma, suggesting at least two pulses of magmatism are represented in the granitoid suite. Two...
