    Description:

        Abstract:
            This digital map database, compiled from previously published and unpublished data, and new mapping by the authors, represents the general distribution of bedrock and surficial deposits of the Santa Rosa 7.5-minute quadrangle. The database delineates map units that are identified by general age and lithology following the stratigraphic nomenclature of the U.S. Geological Survey. The scale of the source maps limits the spatial resolution (scale) of the database to 1:24,000 or smaller. 
        Purpose:
            This database and accompanying plot files depict the distribution of geologic materials and structures at a regional (1:24,000) scale. The report is intended to provide geologic information for the regional study of materials properties, earthquake shaking, landslide potential, mineral hazards, seismic velocity, and earthquake faults. In addition, the report contains new information and interpretations about the regional geologic history and framework. However, the regional scale of this report does not provide sufficient detail for site development purposes. 
        Supplemental_Information:
            DIGITAL COMPILATION-Several different feature classes were generated within a geodatabase during the construction of the Santa Rosa quadrangle geologic map. The topographic base map remains as a digital raster graphic (DRG) and is overlain on the geology feature class in ArcMap at a 60% transparency level. Some custom menus were used to project, transform, edit, tag, and build points in the map. A digital layout or map collar was made with Adobe Illustrator. The map was exported from the layout view in ArcMap as an Adobe Illustrator file and added to a single Adobe Illustrator file that also contained the description of map units, correlation of map units, cross sections, and an index map. Differences between the maps as they appear in the final map sheet and as they appear in the either the .mxd or .pmf files represent changes made in the Adobe Illustrator file to the symbology only and do not reflect any changes in the actual source data. The map is in UTM projection, zone 10, meters, and 1:24,000 scale. The explanatory pamphlet was saved to PDF from Microsoft Word.

            BASE MAP-The base map for the digital compilation is a Digital Raster Graphic (DRG) of the U.S. Geological Survey, 1:24,000-scale topographic map of the Santa Rosa 7.5' quadrangle (1980), which has a 20-foot contour interval. The image inside the map neatline is georeferenced to the Universal Transverse Mercator projection, zone 10. The horizontal positional accuracy and datum of the DRG matches the accuracy and datum of the source map. The base map layer is a digital image, but no information other than location is attached to the lines. The base map is provided for reference only.

    Access_Constraints: None

    Use_Constraints:
        Spatial Resolution-Uses of this digital geologic map should not violate the spatial resolution of the data. Although the digital form of the data removes the constraint imposed by the scale of a paper map, the detail and accuracy inherent in map scale are also present in the digital data. The fact that this database was edited for a scale of 1:24,000 means that higher resolution information is not present in the dataset. Plotting at scales larger than 1:24,000 will not yield greater real detail, although it may reveal fine-scale irregularities below the intended resolution of the database. Similarly, where this database is used in combination with other data of higher resolution, the resolution of the combined output will be limited by the lower resolution of these data.

OBrian, and Dr. T. Stashak for their help in accessing lands in the northeastern Santa Rosa Quadrangle.  The Armstrong family (Cloverleaf Ranch) provided access to their property in the northwestern part of the map area.   We thank Mr. and Mrs. J. Jones, the Witt family, Mr. B. Axell of Jackson Family Farms Vineyards, the Bertram family (Bertram Vineyards) and Mr. and Mrs. S. Adams for their help with access logistics in the Taylor Mountain area.  Property owners who provided access or background information for work in the Bennett Valley area include the Guanella family, Mr. and Mrs. C. Stevens, Mr. and Mrs. G. Bunas and Mr. J. Johnson. 	T. Meyskens and J. McCray, Rangers for Sonoma County Regional Parks and Recreation are herein gratefully acknowledged for their cooperation in assisting us with access to roads and trails in Spring Valley Reservoir and Hood Mountain County Parks.  J. Crossman, M. Baumgratz and W. Noel, of California State Parks and Recreation Department also helped with access and permits for our work within Annadel State Park.

	Sonoma County Water Agency provided rock samples and water well drilling information, which were helpful in determining subsurface stratigraphy in parts of the Santa Rosa Plain.  We also thank J. Howard of California Division of Safety of Dams (DSOD) for providing helpful background information regarding the construction of and pre-dam conditions in the area of Santa Rosa Creek Reservoir.

Tinsley and S. Hecker, (all at the U.S. Geological Survey, Menlo Park, CA); D. Sweetkind and E. Taylor (U.S. Geological Survey, Denver, CO); and C. Farrar (Water Resources Division, U.S. Geological Survey, Lake Tahoe, CA).  All of these scientists have contributed intellectual and scientific support to this mapping investigation and we herein thank them for productive discussions and exchanges of information in the office and field.

	 Additional scientific support from the U.S. Geological Survey that has contributed significantly to this mapping investigation includes paleontologic support provided by S.W. Starratt (diatoms) and E. Wan (benthic foraminfers), C.L. Powell, II. (invertebrate fossils), and C.A. Repenning (vertebrate fossils).

	Laboratory support for tephrochronology including separation and analysis of tephra and database maintenance was provided by E. Wan and D. Wahl (U.S. Geological Survey, Menlo Park).  Rock grinding and analytical support for radiometric dating was provided by D. Shamp (U.S. Geological Survey, Menlo Park).

	McLaughlin also thanks D. L. Zieglar, retired exploration geologist, Chevron Oil Company for the several discussions we have had on the subsurface geology of the Santa Rosa Plain from oil and gas well logs.  These discussions provided useful insights into the regional stratigraphy of the Tertiary volcanic and sedimentary section.

	Funding  for this mapping investigation was provided by the National Cooperative Geologic Mapping and National Earthquake Hazards Reduction Programs of the U.S. Geological Survey.

Based on stratigraphy and the ages of underlying and interbedded volcanic units, we interpret the age of the fluvial and lacustrine deposits of Humbug Creek to be 3.3-4.4 Ma.

Petaluma Formation strata were deposited in fluvial, lacustrine, and brackish to estuarine settings and the formation locally contains the 6.26  0.4 Ma (Ar-Ar) Roblar tuff.  Depositional settings are locally constrained by invertebrate fossils, diatoms, ostracodes, rare foraminifers and rare land mammals.  The formation locally includes interbedded gravel with well rounded and polished pebbles of banded porcellanite, milky quartz and black chert and argillite correlative with the gravels of Cotati (Fox, 1983), a lithofacies of the Petaluma and Wilson Grove Formations. The Petaluma Formation is older than ~4.8-5.0 Ma and younger than ~8.0 Ma where exposed along the E side of Santa Rosa Plain.  Beneath the Santa Rosa Plain and southwest of Cotati and Rohnert Park, the lower Petaluma Formation is intercalated with the older, ~8.5-10 Ma Tolay Volcanics, and overlies Mesozoic basement of the Franciscan Complex, Coast Range ophiolite and Great Valley sequence.
