The Elsinore quadrangle is located in the northern part of the Peninsular Ranges Province and includes parts of two structural blocks, or structural subdivisions of the province. The active Elsinore Fault Zone diagonally crosses the southwest corner of the quadrangle, and is a major element of the right-lateral strike-slip San Andreas Fault system. The Elsinore Fault Zone separates the Santa Ana Mountains block west of the fault zone from the Perris block to the east. Internally both blocks are relatively stable and within the quadrangle are characterized by the presence of widespread erosional surfaces of low relief.Within the quadrangle the Santa Ana Mountains block is underlain by undifferentiated granitic rocks...

The Santa Ana Quadrangle is in the northern part of the Peninsular Ranges Province as defined by Jahns (1954), except for the northeast corner, which is underlain by basement rocks of the Transverse Ranges Province. A summary of the general geology of the Peninsular Ranges Province is given by Jahns (1954) and a generalized geologic map of this part of the Peninsular Ranges Province is given by Rogers (1965). This report provides a digital representation of this quadrangle.

The Yucaipa 7.5' quadrangle is located at the southeastern margin of the SanBernardino Basin, an extensional region situated within a right-step-over zonebetween the San Jacinto and San Andreas Fault zones. The quadrangle is traversed byseveral faults of the San Andreas system, including (from oldest to youngest) theBanning Fault and the Wilson Creek, Mission Creek, Mill Creek, and San BernardinoStrands of the San Andreas Fault.The Mill Creek Strand of the San Andreas Fault is the easternmost strand of the SanAndreas in the Yucaipa quadrangle. It separates granitic and metamorphic rocks ofthe San Bernardino Mountains block from a thin slice of similar rocks on YucaipaRidge, and thus has only a small amount of strike-slip...

The Redlands 7.5' quadrangle is located in the southeastern margin of the San BernardinoBasin, an extensional region situated in a right-step-over zone within the San AndreasFault system. The quadrangle is traversed by several important fault zones, including:(1) northwest-trending right-lateral strike-slip faults of the San Andreas system(Banning Fault, the Mission Creek and San Bernardino Strands of the San Andreas Fault,the San Jacinto Fault); (2) northeast-trending normal dip-slip faults that havedowndropped the San Bernardino Basin; (3) east-trending contractional faults of the SanTimoteo Canyon Fault zone. Some of these faults bound distinctive packages ofcrystalline basement rock.Northwest of the Mission...

This data set maps and describes the geology of the Lakeview 7.5' quadrangle, Riverside County,California. The quadrangle encompasses part of the northern Peninsular Ranges Province.Tonalitic granitic rocks of the Cretaceous Peninsular Range batholith dominate the bedrockareas, and include rocks ranging in composition from monzogranite to gabbro. The LakeviewMountains are underlain chiefly by tonalite of the Lakeview pluton and related rocks. In thenortheastern corner of the quadrangle, Tertiary sedimentary rocks of the San Timoteo beds ofFrick (1921) and Mount Eden Formation of Fraser (1931) rest on Paleozoic schist, quartzite,gneiss, and marble having a well developed east dipping foliation. The Tertiary formations...

Dust samples taken annually for five years from 55 sites insouthern Nevada and California provide an unparalleled sourceof information on modern rates of dust deposition, grain size,and mineralogical and chemical composition. The relations ofmodern dust to climatic factors, type and lithology of dustsource, and regional wind patterns shed new light on theprocesses of dust entrainment and deposition.A project to study modern dust deposition relative to soils insouthern Nevada and California was initiated in 1984 under theauspices of the Yucca Mountain Site Characterization Project(Interagency Agreement DE-AI08-78ET44802). The primary purposeof the dust-deposition project was to provide data on moderndust composition...
