Visible/Infrared Spectroscopy Data from Neoproterozoic Epithermal Systems of the Western Avalon Zone (NTS Map Areas 2C/12, 13; 2D/1, 8, 9; 1L/13; 1M/3, 6, 7, 9, 10, 11, 15, 16), Newfoundland

This open file release consists of Visible/Infrared Spectroscopy (VIRS) data for rock samples collected along the western margin of the Avalon Zone of Newfoundland (NTS map areas 2C/12, 13; 2D/1, 8, 9; 1L/13; 1M/3, 6, 7, 9, 10, 11, 15, 16). A review of the VIRS technique and its applications can be found in Kerr et al. (2011) and references therein. The spectral data presented in this report was collected from both outcrop samples and diamond-drill core around areas hosting the development of Neoproterozoic epithermal alteration and related mineralization. Samples were collected as part of a mineral deposit study aimed at understanding the nature and timing of these uniquely preserved systems, which include both high- and low-sulphidation styles of epithermal mineralization. A summary of the various epithermal prospects and the related styles of alteration formed along the western margin of the Avalon Zone in Newfoundland can be found in Sparkes (2012), and Sparkes and Dunning (2014) and references therein.
