Abstract:
The Boundary Zone prospect (Yukon, Canada) is a Zn-Pb-Ag prospect hosted by siliciclastic rocks in the Macmillan Pass district. The main host units comprise the Late Ordovician to Early Silurian Duo Lake Formation and the Middle to Late Devonian Portrait Lake Formation. Sulfide mineralization is hosted in mudstones, conglomerates, diamictites, and volcaniclastic rocks, with stratabound, vein, and breccia-hosted sulfides consisting of sphalerite, pyrite, galena, with minor chalcopyrite and sulfosalts.
This data publication comprises results of analyses conducted on drill core samples obtained from the Boundary Zone. The data originates from multi-scale petrographic examination, quantitative X-ray diffraction (QXRD), electron probe microanalysis (EPMA), and secondary ion mass spectrometry (SIMS) U-Pb fluorapatite geochronology. All the analyses were caried out at the GFZ German Research Centre for Geosciences, Potsdam, Germany.
