Coverage Name: orgeol
Descriptive Location: Oregon
Brief Description: Oregon lithology. Faults are in a
separate coverage. The legend for southeastern Oregon is in the
coverage orlegend.
SOURCE Data Source: Walker, G.W., and MacLeod, N.S., 1991, Geologic map of Oregon: U. S. Geological Survey, scale 1:500,000, 2 sheets. Point of Contact: For creation of orginal digital data, Harry Casler, NMD Western Mapping Center Telephone: 415/329-4273 Source Material (paper, mylar, digital): mylar Source Scale: 1:500,000 Source Projection: Lambert Source Date (Publication date): 1991 General Comments (disclaimers, qualifications): The map was originally compiled on 1:400,000-scale quarters of the early 1980's version of the Oregon base map for publication at 1:500,000. These data were digitized by USGS NMD Thematic Map Unit and then reprojected to the new (late 1980's) Oregon 1:500,000-scale state base map. This digital work was done primarily in the Scitex sytem. Conversion of scitex products for publication to ARC/INFO format was done to create this coverage. The major task in this conversion was translation of the Scitex color parameters to the map unit names used in ARC/INFO. Date Received: Winter, 1992 LOCAL RESPONSIBILITIES Responsible Organization/Agency: Reno Field Office/WMR/USGS Project Name: Great Basin Mineral Assessment/NAMRAP Point of Contact: Gary Raines Telephone: 702/784-5591 UPDATES Date: Winter, 1992 Name: Gary Raines Description of update: Roger Ashley and others familiar with the geology checked a proof print and found half a dozen errors on the printed version that were incorporated. These occurred primarily in western and northeastern Oregon. Comments: Date: August 26, 1993 Name: Gary Raines Description of update: From Marshall Gannett (USGS WRD), 5 polygons in the Willamette drainage basin were mislabeled. Polygon #1137 was Qpl and is changed to Qal. Polygon #5427 was Qpl and is changed to Tfee. Polygon #3582 was Pzs and is changed to OW (open water) for Marion Lake. These two were mislabeled on published map. Polygon #4186 was Tsfj and is changed to Tut. Polygon #2772 was KJg and is changed to QTa. This polygon was properly labeled on printed map. Comments: The mistaged KJg might occur elsewhere. It is not clear to me how this error occurred.

This table was developed by Kathy Connors for southeastern Oregon only. PYTPE is the map unit. LITH are the lithologies included in the map unit, where LITH01 is the most common and the last listed is the least common. GENLITH is the short description of the map unit. The AGE items have to do with the geologic age. FM lists the formations associated with the map units. LOC are the location of the mentioned formations. EXTRA is for miscellaneous other information.
