Summary:

Shown on geologic sketch map of batholithic areas west of Similkameen River along international boundary. Is a coarse-grained, light, pinkish-gray biotite granite of common macroscopic habit. Includes an informal "Younger phase" which intrudes older coarse granite. Cathedral granite intrudes Remmel granodiorite, Similkameen granite (new), remnant Paleozoic schists, and possibly through Cretaceous strata. Age is Tertiary.
[Type locality not stated. Named from Cathedral River.]

Summary:

Cathedral Leuco Quartz Monzonite in /Horseshoe Basin magma series [informal] (new). Previously called Cathedral Granite by Daly (1906). Mapped in Toats Coulee Creek region, Okanogan Range, Washington. Is a light-pink, coarse-grained, homogeneous, leuco quartz monzonite. Age is Early to medial Cretaceous, based on radiometric (K-Ar, biotite) age of 94.0 +/-2.8 Ma (citing Hawkins, 1968).
["Horseshoe Basin magma series" considered informal. Term "Series" is applied formally only to chronostratigraphic units (ACSN, 1961, 1970; NACSN, 1983, 2005, 2021).]
