Geochemical Data Related to Volcanogenic Massive Sulphide Mineralization, Buchans-Roberts Arm Belt, Central Newfoundland (NTS Map Areas 12H/01 and 08)

G.W. Sparkes

St. John’s, Newfoundland, April, 2019

Summary

This Open File release contains whole-rock geochemistry for 165 grab samples collected in 2017 from within the central portion of the Buchans-Roberts Arm belt. These samples were collected in relation to ongoing, deposit-level studies of volcanogenic massive sulphide occurrences in the region (NTS 12H/01 and 08). Sample sites are focused around known occurrences of base-metal mineralization and include representative samples of both mineralized and altered material as well as relatively unaltered country rock. A preliminary description of some of the occurrences sampled are found in Sparkes (2018).
