Preface
In June 1965, a small group of European economic geologists gathered in Heidelberg,
Germany, at the invitation of Professor G. C. Amstutz and decided to establish the
Society for Geology Applied to Mineral Deposits (SGA) and to start a journal to be
called Mineralium Deposita. The first issue of the journal came out in May 1966, and
has now matured to a leading journal in economic geology The first Biennial SGA
Meeting was held successfully in Nancy, France, in 1991, with subsequent meetings
in Grenada (Spain; 1993), Prague (Czech Republic; 1995), Turku (Finland; 1997), London
(United Kingdom; 1999), Krakov (Poland; 2001) and Athens (Greece; 2003). In 2002,
the SGA Council decided that its 8th Biennial Meeting in 2005 should be held in
Beijing, China, making this the first Biennial Meeting to be convened outside Eu-
rope. Significantly, 2005 also marks the 40th anniversary of the SGA. The decision to
host this year’s premier meeting in Beijing reflects the Society’s successful transition
from its traditional European focus to a truly global organization, with 24% of SGA
members situated in North America, 13% in Australia and Oceania, and 5% in Asia.
Over the last 27 years China has made dramatic progress towards political and
economic reform, and opening the nation to the outside world. China’s rapid eco-
nomic development demands increasing amounts of minerals, fuels and materials,
and this is currently a major driver for the global economic markets. Specifically,
new policies that encourage prospecting and exploration for mineral resources in
western China, are attracting both domestic and international mining corporations.
This 8th SGA Biennial Meeting in Beijing provides outstanding opportunities for rep-
resentatives from academia, government organizations and the industry from around
the world to come together and exchange ideas, foster collaboration, and establish
long-term linkages between China and the global geosciences community.
Three major tectonic metallogenic belts extend, converge and are superimposed
in China, namely the Paleozoic Ancient Asia (or Altaides), the Mesozoic to Recent
circum-Pacific belt, and the Mesozoic/Cenozoic Tethys. Because of this protracted
tectonic evolution, the geological phenomena are complex and diverse. Some Pre-
cambrian mineral deposits occur in China, but the most significant deposits in the
country, with the highest concentration of metallic elements occur within the Meso-
zoic extensional regime of East China, within the Cenozoic post-collision regime in
Tibet and adjourning areas, and within the Paleozoic subduction – collision – post-
collision regime in Xinjiang and Inner Mongolia.
The long mining history in China is reflected by the cover of this volume which
shows a picture of mining potash salt in ca. 1,200 year old incorporated in a book of
“Tian-Gong-Kai-Wu” published in Ming Dynasty (368 years old), and the old Chi-
nese character of “ore”, and the old Chinese character of “ore”. Mining has histori-
cally played a significant role in the development of both China and many of its
neighboring countries. With this in mind, we have arranged 14 sessions focusing on
a diversity of relevant topics that include 1) tectonics, lithospheric, and mantle con-
trols on global metallogenic provinces and giant ore deposits; 2) basin evolution:
base and precious metal mineralization in sediments; 3) uranium deposits: metallogeny
and exploration; 4) magmas and base-metal ore deposits; 5) epigenetic gold systems;
VI Preface
6) submarine ore systems and ancient analogues: global comparisons of VMS (spon-
sored by IGCP-502); 7) understanding ore systems through precise geochemistry,
isotope tracing and microgeochemistry; 8) general economic geology; 9) Mesozoic
to recent geodynamic and metallogeny of eastern Asia; 10) metallogeny of the Tethys-
Himalayan orogen; 11) geodynamics and metallogeny of the Altaid orogen (spon-
sored by both IAGOD and IGCP-473); 12) metallogeny of the Au-Ag-Se-Te mineral-
ized systems (sponsored by both IAGOD and IGCP-486); 13) conceptual targeting of
mineral deposits; and 14) exploration, discovery, and mine developments in China
(sponsored by SEG). Four short courses and workshops will be held prior to the
meeting, i.e. 1) “geochemical mapping – regional national and global”; 2) “metallogeny:
current theory and exploration models”; 3) “gold deposits: new development and
exploration” (sponsored by SEG), and 4) “metallogeny of intrusion-related gold de-
posits in China and adjacent countries”. Another short course on magmatic sulfide
deposits (“geology, geochemistry and exploration” will be offered following the meet-
ing. Moreover, a total of 15 pre- and post-meeting field excursions have been orga-
nized. These field trips will provide the participants with unique opportunities to
visit metallogenic provinces and important deposits in China, Mongolia, Japan, New
Zealand, and Iran.
The response to our invitation to meet in Beijing has been exceptional, with over
450 extended abstracts submitted by authors from 39 countries. Following review
and editing of all submissions by ourselves and a panel of dedicated reviewers (cf.
complete list of reviewers), 400 revised submissions were accepted and are included
in this volume. These papers present a diverse and comprehensive snapshot of glo-
st
bal mineral resources research and exploration at the beginning of the 21 century.
On behalf of the Organizing Committee, we wish to express our sincere gratitude
for the joint sponsorship of the following organizations: China University of Geo-
sciences (Beijing); Institute of Mineral Resources, Chinese Academy of Geological
Sciences; National Natural Science Foundation of China; China Society of Geology;
Society of Economic Geologists (SEG); International Association on the Genesis of
Ore Deposits (IAGOD); Institute of Geology and Geophysics, Chinese Academy of
Sciences; Institute of Geochemistry, Chinese Academy of Sciences; and State Key Lab
for Mineral Deposit Research, Nanjing University. More than sixty students from
around the world and ten professionals from developing countries have received
financial grants to assist their participation in the meeting. This was made possible
by generous financial donations from 17 mining and exploration companies (Anglo
American; Anglogold Ashanti China; BHP Billiton Word Exploration; De Beers; Gold-
fields Australia; Ivanhoe Mines; Newmont Mining; Oxiana Resources; Placer Dome
Exploration; Rio Tinto London; Sino-Oz; Sino Gold; Silvercorp Metals Inc; SRK Con-
sulting; Teck Cominco; Garrison International) and the Specialist Group in Economic
Geology of the Geological Society of Australia.
We are extremely grateful to all co-convenors involved in organizing the scientific
sessions and for their editing of numerous papers with patience, tolerance and dedi-
cation. We also wish to thank the Organizing Committee for their enthusiasm and
hard work that made this meeting possible and ensured its international recogni-
th
tion. We are confident this conference will be a milestone in the 40 anniversary year
th
of our SGA and extend a warm welcome to all participants of the 8 Biennial SGA
Meeting.
