This open file release consists of geochemical data for rock samples collected along the western margin of the Avalon Zone, Newfoundland. These samples were collected from outcrop in areas hosting the development of Neoproterozoic epithermal alteration and related mineralization. Samples were collected as part of mineral deposit studies aimed at understanding the nature and timing of these uniquely preserved systems, which include both high- and low-sulphidation styles of epithermal mineralization. Sample sites are focused around known prospects and include samples of representative alteration as well as unaltered host rocks, where observed. This report does not provide any interpretation of the geochemical data, however summary reports containing a discussion of the various prospects and the styles of epithermal alteration observed in relation to sample collection can be found in Sparkes (2012) and Sparkes and Dunning (2014).
