Primarily tonalite, granodiorite, and minor quartz monzonite and granite. Emplacement ages mostly 80 to 105 Ma in eastern part of area and 105 to 140 Ma in western part; minor Jurassic rocks in central part Lithology: Major:{tonalite}, Minor:{quartz diorite,granodiorite,quartz monzonite}, Incidental:{granite, pegmatite} Reference: Horton, J.D., C.A.

| Cretaceous 66 - 145 Ma | Val Verde Pluton: Val Verde tonalite Age: Cretaceous (66 - 145 Ma) Description: Gray-weathering, relatively homogeneous, massive to well- foliated, medium- to coarse-grained, hypautomorphic-granular biotite hornblende tonalite; is principal rock type of Val Verde Pluton. Contains about equal amounts biotite and hornblende, quartz and plagioclase. Potassium feldspar generally present, but constitutes less than two percent of rock. Where present, foliation typically strikes northwest and dips moderately to steeply northeast. Northern part of pluton contains younger, intermittently developed, northeast-striking foliation. In central part of pluton, tonalite is mostly massive, and contains a few segregational masses of mesocratic to melanocratic tonalite. Elliptical to pancake-shaped, mesocratic to melanocratic inclusions are common. Reference: Morton, D.M., F.K. Miller .
