Contents

This release contains documentation and a 3-D model of 53 Paleozoic bedrock layers plus the Precambrian basement and overburden. Refer to documentation for model layers and associated Groups and Formations.  Topographic layers (i.e., highways, township and county boundaries, lakes, shorelines and major towns) are included for orientation.  Borehole collar locations are provided for reference. The 3-D model in Leapfrog® Viewer format is provided for thorough visual inspection.  To import the model into other 3D modelling applications for further study, 2 additional formats are supplied: 1) Open Mining Format (OMF) v0.9 and 2) A set of model layer volumes in DXF format.
