Cretaceous - Jurassic
66 - 201.3 Ma

ID: 3051060
Franciscan Complex, undivided

Age: Mesozoic (66 - 201.3 Ma)

Stratigraphic Name: Franciscan Complex

Description: The Franciscan is a subduction complex consisting of a disrupted mixture of diverse rock types. Franciscan rock types have not been subdivided over much of the map area. Rock masses large enough to be shown on this map are depicted as cg, ss, ch, gs, um, bs, ls, or gb.
