IGC 35: Sessions sponsored by IAGOD

35TH INTERNATIONAL GEOLOGICAL CONGRESS

27 AUGUST - 4 SEPTEMBER 2016  |  CAPE TOWN, SOUTH AFRICA

Sessions sponsored by IAGOD:

From Ore Deposits to Global Metallogeny: implications for exploration success

CONVENERS: Mao Jingwen, Franco Pirajno, Reimar Seltmann, Zhaoshan Chang, Richard Goldfarb

The session comprises papers on all aspects of key study of genesis of ore deposits, the regional metallogeny and its related tectonic settings, mineral prospecting and exploration with mineral models, geodynamic models and integrated methods of geology, geochemistry, geophysical and remote sensing, as well as introduction of new discovery and new explored ore deposits over the world.

Processes governing ore formation in the Bushveld Complex and other mafic and ultramafic magmatic systems
CONVENORS: Dave Holwell, Rais Latypov (IAGOD-CODMUR)   

Mafic-ultramafic magmatic systems are the world’s most important repositories of Ni-Cu-PGE sulfide and Cr-V-Fe-oxide deposits, with the style, grade and size of deposit governed by a range of processes. This special session will cover all aspects of ore-forming processes associated with mafic-ultramafic magmatic systems, including, but not exclusive to, the Bushveld Complex of South Africa. The emphasis will be on emplacement dynamics, processes that trigger sulfide saturation, precious and base metal partitioning, physical and chemical associations of metals with sulfides and oxides, the role of crustal contamination, alteration and upgrading processes, advancements in exploration models, especially for unconventional styles of deposit. New developments in our understanding of established deposits are also welcomed.

Ore-forming processes associated with hypabyssal magmatic and related volcanic systems   
CONVENERS: David Lentz, Fernando Tornos, Brian Rusk, Khin Zaw, Jian-Wei Li

Hypabyssal or subvolcanic systems at or near the Earth’s surface host many of the world’s most important types of mineral deposits from giant porphyry Cu-Mo-Au deposits to epithermal Au, iron-oxide copper and gold (IOCG), submarine base-metal exhalites, and critical resources (W-Sn to U to to Li-Ta to REE-Y-Nb). This symposium will cover all aspects of ore-forming processes associated with hypabyssal magmatic and related volcanic systems, with emphasis on emplacement dynamics, thermal and hydrologic evolution, magmatic specialization, volatile exsolution, metal – halogen partitioning, fluid-rock reaction, and conditions favourable for focusing and saturation of those ore-forming fluids.

Trace element analysis of minerals: applications in ore geology 
CONVENER: Nigel Cook

The session will include papers on all aspects of trace element analysis of minerals, including new techniques, methodology, applications to understanding ore genesis, mineral exploration and ore processing.
