SEG 2025 Field Trip: Sn-W Deposits and Rare-Metal Mineral Systems of Northeast Queensland, Australia
September 23 @ 8:00 am - September 25 @ 6:00 pm

This 3-day pre-conference field trip will provide a hands-on introduction to the geology of Sn-W mineral system, through a combination of field, mine and local museum visits. Participants will review mineralization and alteration characteristics of Sn-W porphyries and associated polymetallic systems which formed in response to a prolonged magmatic activity during the Paleozoic tectonic evolution of the eastern margin of Australia.
These deposit types were produced by one of the most significant granite-related Paleozoic Sn-W mineral systems in Australia. Key featured deposit types include vein tin (Herberton), polymetallic Cu-Sn-In (Baal Gammon) and Sn-Ag-Pb-Zn (Dover Castle) vein deposits, vein W (Mount Carbine) and W-Mo-Bi greisen (Wolfram Camp) – each type represented by the largest deposit in Queensland. The trip will also visit museums in Herberton where the participants will learn about the rich history of tin deposits in the region.
The field trip is jointly organised by the Geological Survey of Queensland and EGRU.
