(Applies to: mineralization) According to BC MINFILE: "the Britannia ore deposits were formed from hydrothermal solutions genetically related to dacitic volcanism. Massive zinc, zinc-copper and copper deposits were formed near the contact of dacite tuff breccia and overlying fine andesitic tuff and sedimentary rocks. Siliceous stringer zones were formed in the dacitic tuff breccia and grade upward into massive deposits. Massive to disseminated bodies of anhydrite, pyrite, and minor barite were formed near the orebodies from exhalite solutions. Cherty andesitic sedimentary rocks are common near the orebodies." |
