Purpose: Chemical analyses for samples from the Sauvie Island quadrangle. Spatial_Domain: Bounding_Coordinates: West_Bounding_Coordinate: -122.874513 East_Bounding_Coordinate: -122.820540 North_Bounding_Coordinate: 45.703731 South_Bounding_Coordinate: 45.626367 Keywords: Theme: Theme_Keyword_Thesaurus: None Theme_Keyword: chemical analyses Access_Constraints: None Use_Constraints: Users of this geospatial database and geologic information derived from it should acknowledge the U.S. Geological Survey as the source of the data. 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.
