Triassic
201.3 - 252.17 Ma
Wallowa Terrane; Sparta Complex

Age: Triassic (201.3 - 252.17 Ma)

Description: Gabbro; metamorphosed plutonic rocks; mafic composition lithologies; gabbro; coarse crystals; sheared

Lithology: Major:: {gabbro, dark gray; coarse peridotite schlieren; alteration: hydrothermal; mineralogy: orthopyroxene clinopyroxene hornblende} Minor:: {amphibolite}; Minor:: {chlorite schist, bluish black}

Triassic - Permian
201.3 - 298.9 Ma
Gabbroic rocks

Age: Phanerozoic (201.3 - 298.9 Ma)

Description: Most gabbro genetically related to ultramafic rocks, but some probably derived from metamorphism of Triassic and older volcanic rocks

Comments: Not present on State map (OR001) in northeastern Oregon, but, in La Grande 30' x 60' quadrangle (OR291) may be mapped as amphibolite, metagabbro, and metadiorite (Triassic and Permian)

Lithology: Major:{gabbro}, Minor:{andesite}
