Geofile 2018-3 contains the results, methods, and quality control data from geochronological analyses of samples collected during fieldwork conducted as part of the Federal Geo-mapping for Energy and Minerals (GEM) program near the British Columbia Yukon border, in the Atlin area. In 2016, systematic quadrangle mapping activities conducted under GEM focused on a critical boundary segment between Stikine volcanic arc and Cache Creek oceanic crustal terranes in the Turtle Lake area northwest of Atlin. Results of that mapping, and implications of most of the data included in this Geofile, are discussed in Mihalynuk et al., Fieldwork 2017. Geological frameworks for the samples dated are provided in Mihalynuk et al., Fieldworks 2017 and 2018) and some of that material is paraphrased in this Geofile to provide context for the data presented.
