Abstract: This digital release updates data published previously as MRD 273–Revised (released in 2013), with the addition of 21,420 magnetic susceptibility measurements acquired in 18 new geological mapping projects conducted between 2013 and 2017 (inclusive) by the Earth Resources and Geoscience Mapping Section of the Ontario Geological Survey. The merged data set now contains almost 50,225 sets of outcrop readings obtained between 2001 and 2017 from 64 projects and which are presented in ESRI® ArcMap® document (.mxd), geodatabase (.gdb) and shapefile (.shp) formats and a comma delimited (.csv) file in Microsoft® Excel® 2016. Provincial-scale base (map) data for the province boundary (.gdb), drainage (.gdb) and township or area outlines (.shp) are also included. A report describing the instrumentation, data acquisition, processing and sources, and data usage is included as a portable document format (.pdf) file. A template for field data collection, as a macro-enabled spreadsheet, Microsoft® Excel® 2016 (.xlsm), is also provided.
Purpose: The data were collected as part of an effort to obtain rock property (magnetic susceptibility) information during the field mapping projects for interpretation and modeling purposes.
