| Résumé : |
Quartz-carbonate-Au vein deposits in the Timmins-Porcupine gold camp, Abitibi greenstone belt, have equivocal protracted parageneses and formed during late to post-Kenoran (2750–2670 Ma) deformation and metamorphism. Secondary ion mass spectrometry (SIMS) U-Pb, δ18O, and laser ablation-inductively coupled plasma-mass spectrometry (LA-ICP-MS) rare earth element (REE) depth-profiling techniques were employed on unpolished wall-rock zircons to resolve temporal constraints on mineralization and hydrothermal fluid sources at Hoyle Pond and Pamour Mines. Depth-profiling techniques successfully uncovered |
