This information on rock units at or nearby to the coordinates given for this locality is based on relatively small scale geological maps provided by various national Geological Surveys. This does not necessarily represent the geology at this locality but it gives a background for the region in which it is found.

Zanclean - Aquitanian
3.6 - 23.03 Ma
Tertiary volcanic flow rocks, unit 16 (Northern Mojave Desert)

Major:{rhyolite,basalt}, Minor:{dacite}, Incidental:{trachyte, andesite, basaltic andesite}

Tertiary volcanic flow rocks; minor pyroclastic deposits.

23.03 - 66 Ma
Paleogene volcanic: intermediate rocks

Volcanic: intermediate rocks

66 - 145 Ma
Cretaceous plutonic rocks

Plutonic rocks

Deep-seated to high-level intrusions are included. Many charnockites, anorthosites, and large ophiolites, classified as plutons, are distinguished in the database using the SIGNIF item. Ophiolites were classified as plutons, even where remnants may be extrusive and/or sedimentary.
