...Thomas PETTKE; Larryn W. DIAMOND; Jan D. KRAMERS Abstract Identifying the source of the hydrothermal fluid responsible for mesothermal gold lodes in orogenic belts has proven to be a formidable hurdle. As a consequence, several key aspects of the genesis of this worldwide class of deposits remain...

... Abstract Although the currently accepted syngenetic model of ore genesis for volcanic-hosted massive sulfide (VHMS) deposits was established in the 1950s and early 1960s based largely on field relationships (King and Thomson, 1953; Stanton, 1955), more detailed understanding of this deposit...
