Contents

This release contains documentation and a 3-D model of 54 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.  A model overview tour is included as a Portable Document Format (PDF). The overview is a set of graphics and screen captures from the model highlighting geological features of interest.  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) Model layer sampled with a 3D array of points at 400m x 400m x 10m spacing in CSV format.  This can be translated to a 3D block model with grid points as block centroids.  2) A set of model layer volumes in DXF format.
