Relationship Between Magmatism/Volcanism, Deformation and Economic Mineralization within Paleozoic Strata in the Terrace-Kitimat Area, British Columbia (NTS 103I)
- Geoffrey Pignotta, University of Wisconsin
Economic mineralization in the Terrace‐Kitimat area is concentrated along the intrusive boundary between the eastern margin of the Coast Plutonic Complex (CPC) and supracrustal rocks of Stikinia. Recent regional mapping by the British Columbia Geological Survey indicates that Paleozoic volcanogenic and marine sedimentary strata (Zymoetz Group) host potential Volcanic‐Hosted Massive Sulphide (VHMS) mineralization (Nelson et al., 2008a; McKeown et al, 2008). This newly discovered VHMS potential is believed to be analogous to other VHMS deposits found in Stikinia (e.g., the Tulsequah Chief deposit) that are characterized by massive sulphide lenses, disseminated sulphides and syngenetic alteration of felsic volcanics to quartz‐sericite schist.
The primary objective of this project is structural analysis, geochemical characterization and economic mineral assessment of several exposures of Zymoetz Group rocks. This will be accomplished through:
These analyses will constrain the nature and timing of economic mineralization within these rocks, and assess the regional economic potential in the Terrace‐Kitimat area.
