These relationships suggest that folding, faulting, and metamorphism all have the same cause. Researchers now agree that most folding, thrust faulting, and metamorphism are related to the movement of plates, but few have described the details of how plate Abstract. The development of the western Cordillera of North America perhaps began with the submergence of the western border of the craton in middle to late Proterozoic time and the deposition of the thick Beltian sequence of dominantly shallow-water clastic sediments of presumed marine ://

Franciscan rocks in the Bay Area range in age from about Ma to 50 Ma (see papers in Blake,Snow et al., ).They represent an accretionary wedge; a complex body of rock that accumulates in a subduction zone (Hamilton,Ernst, ). Rocks of Mesozoic age crop out extensively through the coast ranges of Central and northern California.
In the San Francisco Bay region, rocks assigned to the Franciscan Formation consist of rocks in the Pacific Ocean basin and along the western continental margin. The Franciscan Formation, sometimes referred to as an "assemblage" or "basement This digital map database, compiled from previously published and unpublished data, and new mapping by the authors, represents the general distribution of bedrock and surficial deposits in the mapped area.

In general, mélange origins are attributed to sedimentary, tectonic, or diapiric processes—or a combination of these. Published reviews list the main features of mélanges characteristic of each type of origin.

K‐Ar ages from pre‐ references have been recalculated to more recent decay constants using the method of Dalrymple. Age range generally reflects scatter and uncertainty instead of documented duration of activity.
Within age groups, values are sorted by latitude. YM1: 27‐25 The structural relations here are unusual, in that the dip of shear-fracture fabric in both serpentinite and Kflg sandstone and shale is to the northeast, placing the serpentinite structurally beneath the clastic rocks.

Despite the ubiquity of shelf-edge collapse along continental margins, outcrop exposures of collapsed shelfal or deltaic deposits are relatively uncommon, with some exceptions (e.g., Nemec et al., ; Odonne et al., ).Submarine mass movement associated with shelf-edge deltas has been more commonly documented in historic examples (e.g., Anthony and Julian, ) and by seismic-reflection Introduction.
