| Comments | KXmix consists of mixed Cretaceous (K) granitoid intrusions and Proterozoic (ZX) metasedimentary rocks around the margins of the Kaniksu and Idaho batholiths. Much KXmix is migmatitic ID020, but some is agmititic, especially along the eastern margin of the Atlanta lobe of the Idaho batholith. |
