Just a quick note. I haven’t done this in a while, but I’m restarting this component of the blog again: notifying people when new papers come out from my research group.
Dr. Jonathan Cloutier, my former Post-Doctoral Fellow and now a Lecturer at University of St. Andrews, recently published a paper entitled “Lithostratigraphic and structural reconstruction of the Zn-Pb-Cu-Ag-Au Lemarchant volcanogenic massive sulphide (VMS) deposit, Tally Pond group, central Newfoundland, Canada.” The paper is an integrated study that utilizes lithostratigraphy, structure, and lithogeochemistry to reconstruct the original geometry of mineralization at the Lemarchant deposit. The work also evaluated the lithogeochemistry and petrogenesis of host rocks to mineralization to illustrated that they formed in a mid-Cambrian (continental) arc sequence along the edge Ganderia (i.e., peri-Gondwananan). He also argued, based on a number of lines of evidence, that the deposit formed in shallow water (<1500 m) in a migrating cross-arc seamount chain and that this tectonic and hydrologic setting resulted in fluid boiling and the precious metal enrichment found in the Lemarchant deposit. He also argued that cross-arc chains in rifted arcs may be important targets for precious metal-enriched VMS deposits.
