“…The Sierr~ Nevada batholith is composed of numberous of individual plutons of granitic rock that were emplaced during a long period-more than 100 m.y.-beginning in the Triassic and ending in the Late Cretaceous (Evernden and Kistler, 1970). The granitic rocks within the study area are considered to be part of this composite batholith, and rocks of at least 10 different plutons covering the entire age span are present.…”

“…The biotite age is the same as the average age (78 m.y.) for the adjacent Cathedral Peak-type rocks (Evernden and Kistler, 1970). However, biotite loses argon more readi\y than hornblende when both are heated by an adjacent intrusion (Hart, 1964), and the significantly older hornblende age is taken as a minimum for that of the granodiorite of Lost Dog Lake.…”

“…Of the three major periods of intrusive activity (Evernden and Kistler, 1970) in the Kern Plateau region, only the younger two are represented within the study area. The granitic rocks intruded and metamorphosed Paleozoic and (or) Mesozoic sedimentary rocks that form small roof remnants of quartz-biotite-muscovite schist, phyllite, and quartzite.…”

Granitic plutons commonly preserve evidence for jointing, faulting, and ductile fabric development during cooling. Constraining the spatial variation and temporal evolution of temperature during this deformation could facilitate an integrated analysis of heterogeneous deformation over multiple length‐scales through time. Here, we constrain the evolving temperature of the Lake Edison granodiorite within the Mount Abbot Quadrangle (central Sierra Nevada, CA) during late Cretaceous deformation by combining microstructural analysis, titanium‐in‐quartz thermobarometry (TitaniQ), and thermal modeling. Microstructural and TitaniQ analyses were applied to 12 samples collected throughout the pluton, representative of either the penetrative “regional” fabric or the locally strong “fault‐related” fabric. Overprinting textures and mineral assemblages indicate the temperature decreased from 400–500°C to <350°C during faulting. TitaniQ reveals consistently lower Ti concentrations for partially reset fault‐related fabrics (average: 12 ± 4 ppm) than for regional fabrics (average: 31 ± 12 ppm), suggesting fault‐related fabrics developed later, following a period of pluton cooling. Uncertainties, particularly in TiO2 activity, significantly limit further quantitative thermal estimates using TitaniQ. In addition, we present a 1‐D heat conduction model that suggests average pluton temperature decreased from 585°C at 85 Ma to 332°C at 79 Ma, consistent with radiometric age data for the field. Integrated with the model results, microstructural temperature constraints suggest faulting initiated by ∼83 Ma, when the temperature was nearly uniform across the pluton. Thus, spatially heterogeneous deformation cannot be attributed to a persistent temperature gradient, but may be related to regional structures that develop in cooling plutons.
