Working Group on Skarn Deposits

Skarn deposits are one of the most common mineral deposits in the world,with least 1428 skarns in 63 countries documented in literatures. Skarns are also economically important. They are the major sources of Sn and W, and important sources of Mo, Au, Cu, Pb, Zn, and Fe. Silver, B, Be, Bi, Co, F, REE and U are also produced from skarns, plus industrial materials such as wollastonite, garnet, phlogopite, talc and graphite. Exploitation of skarn deposits dates back at least 4000 years in ancient China, Greece, and Roman. Skarns may have close spatial and genetic relationship with other types of deposits, particularly porphyry deposits. In a porphyry deposit district skarns may occur as independent deposits, or as high-grade ‘sweetener’ ore bodiesin a porphyry deposit, and may help vector towards porphyry ore bodies. Skarns may also transition to distal carbonate replacement deposits and carbonate-hosted disseminated Au deposits. Studies of skarns are important to both minerals exploration and to the understanding of hydrothermal deposits.

The IAGOD Working Group on Skarn Deposits aims to promote the research and education on skarn deposits, to facilitate the exchange of ideas, research methods, and reporting of progress in skarn studies, and thereby to help exploration for skarn deposits and related hydrothermal deposits and to improve the understanding of skarn systems. The Working Group will organize meetings, sessions at conferences, short courses/workshops and publications.

The Working Group has a committee composed of a Chair, a Co-Chair and a Secretary. The current committee members are:

Chair: Zhaoshan Chang
EGRU (Economic Geology Research Centre), James Cook University, Townsville, Queensland 4811, Australia.  Email:  Tel: +61 7 4781 6434

Working Group on Critical Metals (WGCM)


Metals that are perceived to have high supply risks have recently been called "critical metals". The exact list of metals that are considered to be critical varies, but typically include indium, gallium, germanium, selenium, tellurium, neodymium, dysprosium, lithium, vanadium, tin, tungsten, molybdenum, rhenium, tantalum, niobium, cobalt and the PGE.

The mission of the Working Group for Critical Metals is to promote and coordinate research into the mechanisms that lead to economic concentration of critical metals. The activities of the group will be coordinated with other IAGOD groups such as CODMUR (PGE, Ni, Cu, Co) and the WGTT (Sn, W and associated rare metals).


2013 Activities of WGCM:

Critical Metals meeting (CM2013), Ulaanbaatar, Mongolia, 3-10 July 2013

Inaugural group meeting at the Biennial SGA Meeting in Uppsala, 12-15 August 2013

Working Group on Iron Ore Copper-Gold Systems (WG IOCG)

The objectives of this new IAGOD WG will be to bring together divergent expertise from researchers around the world to discuss the geology, geological setting, geochemical, petrologic, isotopic, and geophysical aspects of both host rocks and mineralization, with greater geochronologic constraints, that contribute to our understanding of the genesis of various types of deposits that have characteristics of "IOCG" systems. The group will try to build events, especially Special Sessions to facilitate academic exchange of ideas. Furthermore, formal and informal Workshops, Short Courses, and Field Trips will be coordinated to facilitate greater opportunity and dialogue, and hopefully refinement of ideas on the genesis of these fascinating, complex deposit systems. Ideally, developing (more) robust models to explain end-members systems and their related environments of formation will be explored, while reconciling various lines of evidence for their formation.
