Rock Properties

This compilation sources data primarily from the Yukon Geological Survey’s (YGS) field projects and archival collections, and from the Geological Survey of Canada’s (GSC) Canadian rock physical property database (Enkin, 2014, 2018). The data distribution is far from uniform but covers a range of lithology classes and terranes. The compilation of data from archival samples is ongoing, and the dataset will continue to grow as new samples are collected for YGS projects and pass through the survey’s physical properties lab. The foundation of this dataset originates from samples collected for a mapping project in western Yukon led by Dirk Tempelman-Kluit from 1970 to 1972 (Tempelman-Kluit and Curie, 1978) and subsequently digitized by the Geological Survey of Canada and Mira Geoscience (2014). This dataset alone contributed 1642 records to the compilation. Map unit names from this original dataset were modernized for this compilation to reflect current understanding of Yukon geology. Systematic measurements of magnetic susceptibility and specific gravity have been incorporated into the workflow when archiving rock samples from YGS projects. Additional magnetic susceptibility measurements are also routinely collected in the field by YGS geologists. This will continue to expand the dataset. Rock samples are not collected specifically for the physical properties dataset but are well characterized and have sufficient metadata to be incorporated into the dataset. Samples are not uniform in size or weight. The Yukon Geological Survey’s HS Bostock Core Library houses >10 000 Yukon rock samples from previous and ongoing geological studies. Archived collections provide a great opportunity to further expand the dataset in specific regions or areas lacking representation. Distributed from GeoYukon by the Government of Yukon.
