    Description
      Abstract: This digital dataset comprises updated geological unit outlines for the Andrew Lake and Leland Lakes areas on the Canadian Shield in northeastern Alberta. Alberta Geological Survey (AGS) crews conducted fieldwork in the Andrew Lake and Leland Lakes areas for a total of four weeks in the summer of 2023 and recorded geological observations for hundreds of stations, which were then used to update existing geological maps in the areas of interest.

This work was completed under the Mineral Grant provided by the Government of Alberta June 22, 2021.
      Purpose: To provide GIS products generated by the AGS from the fieldwork in the summer of 2023 on the Canadian Shield in northeastern Alberta, including bedrock geology polygons.

Data_Quality_Information
  Attribute_Accuracy
    Attribute_Accuracy_Report: The classification of geological units and their ages have been determined with all available data at the time of publication (i.e., geological observations, whole-rock lithogeochemistry, geochronology).
  Logical_Consistency_Report: Data are contiguous, topologically correct polygons as built and enforced using ArcGIS software.
  Completeness_Report: The updated geological unit outlines were drafted using all information listed under source information.  Historical geological maps served as a starting point for geological units in the areas of interest that were then revised and/or removed at the discretion of the AGS team after considering all recorded geological observations, geochemistry, geochronology, and geophysical data.

Several new geological units have been defined in the study areas. See report OFR 2025-09 for complete descriptions of the units.
  Positional_Accuracy
    Horizontal_Positional_Accuracy
   Horizontal_Positional_Accuracy_Report: Approximately 12 to 16 control points were used to register (georeference) each map provided in the various geological maps used as source information. Examination of the registered image against the 74M National Topographic System 1:50,000-scale maps indicates the positional accuracy is better than +/- 100 m.

Geological boundaries close to shorelines were mapped by AGS crews in 2023. GPS locations for these boundaries are estimated to be +/- 10 m.

Geological boundaries that could not be examined by AGS crews due to limited time or distance from shorelines were inferred using updated geophysical data listed as source information. Horizontal position accuracy is not provided for these products.
