CONTENTS

Along with this readme file, the publication contains: 

1) folder LOWNGeologicMaps: .pdf files of the Preliminary Geologic Map of the Lake of the Woods North 7.5 Quadrangle in 3 size formats (8.5 x 11 in., 11 x 17 in., and 30 x 36 in.) (LOWNMap8.5x11.pdf, LOWNMap11x17.pdf, and LOWNMap30x36.pdf). 

2) Open-File Report O-11-03: Preliminary Geologic Map of the Lake of the Woods North 7.5 Quadrangle, Klamath County, Oregon: a review of the Lake of the Woods North 7.5 minute USGS quadrangle and its geology, including detailed descriptions of the geologic units found therein. (O-11-03_LOWNreport.pdf)

3) folder LOWNMapInfoFiles: Maplnfo® files with the layers used to create the geologic map. Included are the USGS 7.5 minute quadrangle; rock units; unit boundaries (contacts); samples; faults; and volcanic centers layers. Please see the Readme file (ReadmeMaplnfoandShape.txt) for instructions on opening the workspace (LOWN.WOR). 

4) folder LOWNESRIFiles: ESRI® shapefiles (.shp) and an ESRI® ArcMap™ (LOWN.mxd) file of the units; unit boundaries (contacts); samples; faults; and volcanic centers for the Lake of the Woods North 7.5’ quadrangle and a georeferenced raster image (.TIF) of the USGS 7.5 minute quadrangle. Please see the readme file (ReadmeMaplnfoandShape.txt) for instructions on opening the LOWN.mxd file that contains all of the above-mentioned shapefiles and raster image (.TIF). 

5) A Microsoft® Excel file (LOWNTbl1SampleChem.xls) with Table 1 of the OFR O-11-03 that has the location, lithology, age, unit, and chemistry information for all of the rock samples collected within the Lake of the Woods North 7.5’ quadrangle and used to help create the preliminary geologic map of this quadrangle. 

6) LOWNMetadata: Metadata files for the GIS dataset (LOWNMetadata in .htm, .txt, and .xml formats).
