A fluid-flow modeling approach for predictive mapping of orogenic gold mineralization in the Malartic camp, Canada

, 2021
Orogenic gold deposits are structurally controlled and commonly formed in the transition zone between brittle and ductile crustal domains. Formation of disseminated or localized gold mineralization involves structural features (e.g., fault zones, fold ...
