Genesis of Sublayer, Footwall Breccia, and Associated Ni-Cu-Platinum Group Element Mineralization in the Sudbury Igneous Complex

Autor: Yujian Wang, C. Michael Lesher, Peter C. Lightfoot, Edward F. Pattison, J. Paul Golightly

Publikováno v: Economic Geology. 117:1791-1807

The Ni-Cu-platinum group element (PGE) sulfide mineralization in the 1.85 Ga Sudbury impact structure occurs in two discrete environments: (1) mineralization along or near the basal contact, including disseminated to semimassive mineralization in an

Genesis of the Jinbaoshan PGE-(Cu)-(Ni) deposit: Distribution of chalcophile elements and platinum-group minerals

Autor: Yiguan Lu, C. Michael Lesher, Liqiang Yang, Matthew I. Leybourne, Wenyan He, Mingwei Yuan, Zhen Yang, Xue Gao

Publikováno v: The Canadian Mineralogist. 59:1511-1542

The Jinbaoshan platinum group element-(Cu)-(Ni) deposit in southwest China is a sulfide-poor magmatic platinum-group element deposit that experienced multiple phases of post-magmatic modification. The sulfide assemblages of most magmatic Ni-Cu-platin

Genesis and mechanisms of metal enrichment in the Baimazhai Ni-Cu-(PGE) deposit, Ailaoshan Orogenic Belt, SW China

Autor: Yiguan Lu, C. Michael Lesher, Liqiang Yang, Matthew I. Leybourne, Wenyan He

Publikováno v: The Canadian Mineralogist. 59:1543-1570

The ∼259 Ma Baimazhai Ni-Cu-(platinum-group element) deposit is located in the Ailaoshan-Red River fault zone on the southwest margin of the Yangtze Plate in the Jinping area of southeastern Yunnan Province. The intrusion is lenticular (∼530 m lo

Geochemistry and Petrogenesis of Mafic and Ultramafic Inclusions in Sublayer and Offset Dikes, Sudbury Igneous Complex, Canada

Autor: Peter C. Lightfoot, Edward F. Pattison, Yujian Wang, C. Michael Lesher, J. Paul Golightly

Publikováno v: Journal of Petrology. 61

The c. 1·85 Ga Sudbury Igneous Complex (SIC) is the igneous remnant of one of the oldest, largest and best-preserved impact structures on Earth and contains some of the world’s largest magmatic Ni–Cu–PGE sulfide deposits. Most of the mineraliz

Expanding the size of multi-parameter metasomatic footprints in gold exploration: utilization of mafic dykes in the Canadian Malartic district, Québec, Canada

Autor: Nicolas Gaillard, Robert L. Linnen, Stephen J. Piercey, Stéphane Perrouty, James R. Clark, Randolph J. Enkin, Gema R. Olivo, C. Michael Lesher

Publikováno v: Mineralium Deposita. 54:761-786

Ore-forming hydrothermal fluids react differently with different country rocks, but few studies have applied this knowledge with the specific goal of expanding the size of hydrothermal footprints in mineral exploration. To develop this concept, 122 m
