Summary:

Named Mount Givens granodiorite. Crops out in area 10 miles wide and extends northwest for more than 30 miles. Typically light-gray biotite-hornblende granodiorite in which hornblende is in distinct small prisms and uniform over broad areas. Age is Cretaceous.
Named for occurrence around Mount Givens in Huntington Lake area. [Reference locality: exposures in vicinity of Mount Givens, Lat. 37 deg. 16 min. 45 sec. N., Long. 119 deg. 03 min. 17 sec. W., Kaiser Peak 15-min quadrangle (Mt. Givens 7.5-min quadrangle), Fresno Co., CA (P.C. Bateman, oral commun., 1985)].

Summary:

Mapped in northeastern part of Huntington Lake 15' quad. Described as medium grained, equigranular, foliated. Grades locally into quartz monzonite. Contains many disc-shaped inclusions. Intrudes quartz monzonite of Dinkey Dome. Age changed from Cretaceous to Late Cretaceous based on K-Ar ages of 87 to 82 Ma [Kistler and others, 1965].

Summary:

Included as 2nd oldest unit of John Muir Intrusive Suite. Comprises about 1400 sq km; is elongate in northwestern direction, 80 km long and 17 km across S 2/3's and almost twice across a bulge at northern end. Consists of 2 facies (1) equigranular granodiorite and (2) megacrystic facies that is mostly granite but includes some granodiorite. Intrudes all granitoids along western and northern borders except granodiorites of Red Lake and Eagle Peak. On east is intruded by Lake Edison Granodiorite. Intrudes Lamarck Granodiorite. Age is early Late Cretaceous based on U-Pb ages of 93 and 88 Ma (Stern and others, 1981) and K-Ar ages of 89 to 84 Ma (Kistler and others, 1965). True age is about 90 Ma.
