Pliocene
2.588 - 5.333 Ma



ID: 3192320
Cenozoic volcanic rocks

Age: Pliocene (2.588 - 5.333 Ma)

Lithology: Volcanic rocks

Reference: Chorlton, L.B. Generalized geology of the world: bedrock domains and major faults in GIS format: a small-scale world geology map with an extended geological attribute database. doi: 10.4095/223767. Geological Survey of Canada, Open File 5529. [154]

Ypresian - Campanian
47.8 - 83.6 Ma



ID: 2778472
Early Tertiary to Late Cretaceous granitic rocks

Age: Phanerozoic (47.8 - 83.6 Ma)

Description: Porphyritic to equigranular granite to diorite emplaced during the Laramide orogeny. Larger plutons are characteristically medium-grained, biotite +/- hornblende granodiorite to granite. Smaller, shallow-level intrusions are typically porphyritic. Most of the large copper deposits in Arizona are associated with porphyritic granitic rocks of this unit, and are thus named 'porphyry copper deposits'. (50-82 Ma)

Comments: Laramide metaluminous; associated with porphyry Cu deposits Original map source: Arizona Geological Survey, DI-8 Geologic Map of Arizona, Digital Spatial data for the Geologic Map of Arizona, v. 3.0, edited by S.M.
