INTRODUCTION Open-File
Report 01-451 contains a digital geologic map database of the Riverside
West 7.5 quadrangle, Riverside County, California that includes: The Correlation
of Map Units and Description of Map Units is in the editorial format of
USGS Geologic Investigations Series (I-series) maps but has not been edited
to comply with I-map standards. Within the geologic map data package,
map units are identified by standard geologic map criteria such as formation-name,
age, and lithology. Where known, grain size is indicated on the map by
a subscripted letter or letters following the unit symbols as follows:
lg, large boulders; b, boulder; g, gravel; a, arenaceous; s, silt; c,
clay; e.g. Qyfa is a predominantly young alluvial fan deposit that is
arenaceous. |
This illustration is a .jpg non-navigable image of the USGS geologic-map plot of the Riverside West quadrangle, showing only the geologic map area. A full-size, navigable map graphic can be plotted from the PostScript file (rsw_map.ps.gz). Note: the full-size plot is approximately 50 x 36 inches, requires a large-format plotter, and is best reproduced at 600 (or greater) dpi. |
