New alteration zone geochemical analyses are provided as a GIS feature class within a GeMS file geodatabase, a shapefile DESBSR2021_AltChemistry, and as a separate Microsoft Excel® spreadsheet named DWPS2021_AltChemistry.xlsm. This geodatabase contains cartographic representations for point symbols from Section 31 of FGDC Digital Cartographic Standard for Geologic Map Symbolization (FGDC Document Number FGDC-STD-013-2006). Please see the accompanying pamphlet for more detailed information.
This feature class represents point locations where whole-rock samples have been analyzed by Inductive Coupled Mass Spectrometry (ICP-MS), Inductive Coupled Atomic Emission Spectrometry (ICP-AES), and/or X-ray diffraction (XRD) techniques. Includes only data collected by the authors during the course of this study.

Supported in part between 2014 and 2020 by the U.S. Geological Survey (USGS) STATEMAP [http://ncgmp.usgs.gov/about/statemap.html] component of the National Cooperative Geologic Mapping Program under assistance awards G15AC00180 and G20AC00202, and by the Oregon Water Resources Department through Interagency Agreements DOGAMI IAA# 12102013/OWRD 13 057 and DOGAMI IAA# DASPS-2542-16/OWRD IAA 16 047. Additional funds were provided by the State of Oregon through the Oregon Department of Geology and Mineral Industries (DOGAMI).
Care was taken to limit categorical attribute errors. Attribute accuracy of the database was visually inspected but despite the checks there may be some attributes that are still mislabeled.
Topology has been validated for the feature classes. Topology errors: 0. Topology exceptions: 7; MapUnitPolys must not have gaps 1 exception for project boundary of polygons; ContactsAndFaults must not have dangles 6 exceptions for faults. Duplicate point locations were found. No attempt has been made to correct the errors as they are related to multiple samples at one location, retesting of samples, and/or variance in Z values. Tests for logical consistency were performed by ArcGIS Topology software and GeMS Tools for Arc10.5 2018-03-04; Topology Check script and Validate Database script. All points, lines, and polygons were visually checked, and are labelled correctly.
Data collection does not include all possible traverses, measured sections, etc., and thereby is not complete. Not all field data were collected nor were all of the data compiled from lineage maps. Geologic concepts and definitions of map units are current. Density of observations is sufficient to support the map(s).
Data was collected and interpreted at a variety of scales. For field work, a combination of hillshade images from, DOGAMIs lidar 3 ft pixel bare earth DEM (approximately 1 point every 0.3 meters), NAIP imagery derived structure for motion (SFM) 5 m pixel bare earth DEM (approximately 1 point every 5 meters), and/or 10m pixel bare earth DEM (approximately 1 point every 10 meters) served as basemap(s). Precision mapping using, GPS, GIS, and the lidar imagery employed an application for the iPad, called iGIS. On the computer, line work was nominally drawn at a scale of 1:8,000. Also, geologic data was compiled from paper maps. Positional errors should be expected from input of digitized points and lines from paper maps and the errors that arise from georeferencing the paper maps (accuracy of content). Not all resources were tested to evaluate the degree to which these inaccuracies exist. Positional accuracy of geologic contacts, structures, and measurement points is influenced by the subjective judgment of the mappers or by interpretation of remotely sensed data (e.g., lidar). Therefore, the data user must consider the aforementioned methods of data collection and compilation in context of positional accuracy and understand that most lines and polygon boundaries are inferred based on geologic interpretations.
Maximum error calculated from the 1:8000 scale horizontal positional accuracy error.
A combination of lidar 3 ft pixel bare earth DEM (approximately 1 point every 0.3 meters), structure for motion (SFM) derived 5 m pixel bare earth DEM (approximately 1 point every 5 meters), and/or a 10m pixel bare earth DEM (approximately 1 point every 10 meters) served as elevation model(s). Not all resources were tested to evaluate the degree to which these inaccuracies exist. Lidar-derived bare earth elevation model vertical accuracy is typically less than 1 foot.
Maximum error from lidar.
Lineage maps were used as base maps in the following manner: 1) to compare the mapping against previous work; 2) scribing geologic features, e.g., bedding, faults, and folds; and 3) reference materials.
Topology checks were performed on the GeologicMap feature dataset by, employing the Topology check script provided in the GeMS Tools for Arc10.5 2018-03-04, and checking additional topology rules using Esri ArcGIS 10.7 for desktop. The Topology Check script in the GeMS toolkit provides additional checks for automation errors and geologic blunders. This script builds and evaluates an ArcGIS topology with these rules: no overlaps in ContactsAndFaults, no self-overlaps in ContactsAndFaults, no self intersections in ContactsAndFaults, no gaps in MapUnitPolys, no overlaps in MapUnitPolys, and all MapUnitPoly boundaries are covered by ContactsAndFaults arcs. Topology Check also evaluates node topology, summarizes the map units that bound ContactsAndFaults arcs, checks for duplicate point features, and identifies very small polygons in MapUnitPolys and very short arcs in ContactsAndFaults. Results of Topology Check should be taken with a grain of salt, as some issues flagged by this script may not be errors. In addition to the GeMS Topology Check the following are added topology rules checked for the dataset. Rule 1: ContactsAndFaults must not have dangles. Rule 2: Cartographic Lines must not self-overlap. Rule 3: Cartographic Lines must not self-intersect. Rule 4: Cartographic Lines must be single part.
