Cretaceous
66 - 145 Ma



ID: 3192002
Mesozoic intrusive rocks

Age: Cretaceous (66 - 145 Ma)

Lithology: Intrusive igneous 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]

Proterozoic
541 - 2500 Ma



ID: 2664844
Gabbro

Age: Proterozoic (541 - 2500 Ma)

Description: Gray, mottled with greenish or brownish black, and solid dark greenish and brownish black; mafic mineral content ranges from 10 percent to 65 percent of rock; compositionally ranging from gabbroic anorthosite to norite, diorite, pegmatitic hornblende gabbro, and olivine gabbro. Chiefly xenomorphic granular texture; alternating felsic and mafic bands, from a few inches to several feet in thickness are common, but generally discontinuous. Feldspar is mostly calcic andesine (labradorite in more mafic rocks), in many places partly altered to albite or albite-oligoclase. Pyroxenes (and subordinate amphiboles) commonly altered to chlorite, antigorite and biotite (Oakeshott, 1958). (southwestern Agua Dulce 7.5’ quadrangle; Oakeshott, 1958)

Age: Ectasian (1200 - 1400 Ma)

Description: Precambrian granite, syenite, anorthosite, and gabbroic rocks in the San Gabriel Mountains; also various Precambrian plutonic rocks elsewhere in southeastern California

Comments: San Gabriel Mountains.
