at the Batu Hijau porphyry copper-gold
deposit in Sumbawa, Indonesia, with
Newmont Mining Company, and a validation
study to determine whether or
not bomb-pulse 36 Cl has infiltrated the
proposed Yucca Mountain repository
site. The presence of bomb-pulse Cl at
the repository level would confirm the
existence of fast pathways along which
meteoric fluids from the surface reached
depths of 300 m during the past 50
years.
A member of several professional
organizations, Jean has been most
involved in the Geological Society of
Nevada and SEG. Jean is active in the
fluid inclusion community and, with
Dave Vanko, now at Towson University,
hosted the Pan-American Current
Research on Fluid Inclusions Conference
(PACROFI VII) at UNLV in June 1998.
Jean was Vice Chairman of the 2001
Gordon Research Conference on inorganic
geochemistry (hydrothermal ore
deposits) and will co-chair the 2005
conference. She was selected as the
UNLV College of Science Distinguished
Researcher for 2003.1
2004 THAYER LINDSLEY LECTURER
François Robert
François Robert was born in Montreal,
Canada, where he obtained his Geological
Engineering (1978), M.Sc. (1980),
and Ph.D. (1983) degrees from the Ecole
Polytechnique. His Ph.D. focused on the
geological, structural, and hydrothermal
characteristics and evolution of the
Sigma gold deposit in the Abitibi greenstone
belt. In 1984 he spent a year as
postdoctoral fellow at the University of
Michigan, carrying out a fluid inclusion
study of the same deposit.
In 1985, François joined the
Geological Survey of Canada as a
research scientist with the mineral
deposits group. The next 12 years he
spent working on gold deposits in
Canada and abroad. His research
focused largely on the geology, structure,
and settings of lode gold deposits
in a variety of deformed terranes, with a
particular emphasis on greenstone
belts. This led him to examine a large
number of gold deposits in Precambrian
terranes around the world. For one year
(1990–1991) he was at the CRPG in
Nancy, France, working on fluid inclusions
in relation to auriferous vein
microstructures. In 1990, he received
SEG’s Lindgren Award.
In late 1997, François moved to
industry, accepting a position with
Barrick Gold Corporation as senior
research geologist attached to head
office. He assisted with the geologic
understanding of selected Barrick projects
and participated in project evaluations
worldwide. In 2002, he joined
Barrick’s Australian exploration team
as Chief Geologist, the position he currently
holds, with project generation as
one of his main responsibilities.
François will be offering four lectures,
three on greenstone gold deposits and
one on Carlin-type gold deposits. All
lectures will place significant emphasis
on geologic features of gold deposits
and their settings. As such, they are
suitable for a wide range of geologic
audiences, although the first two talks
will be more technical. François is also
prepared to give a short informal presentation
on the role of external
research in a large gold exploration
company.
The four lectures are as follows:
1. Gold-quartz vein field of the Val
d’Or district of Abitibi: A type
example of a synorogenic system
The well-documented gold-quartz
veins of the Val d’Or district will be used
to illustrate the key features of these
classic deposits and the key relationships
used to determine the structural
controls and processes of vein formation,
and their timing and setting in a
regional context. This will also provide
a basis to review the fundamental elements
of the classic “orogenic-mesothermal”
gold deposit model.
2. Giant gold deposits of the Abitibi
greenstone belt and related models
Characteristics of giant Abitibi
deposits and their setting will be
reviewed to illustrate the spectrum of
deposit styles and structural timing.
This will provide a basis for addressing
the question of genetic models for
greenstone gold deposits, linked to the
question of whether the observed diversity
relates to variations in depth of
emplacement of a single deposit type or
to the existence of different deposit
types formed at different times and
crustal depths. The question of distinguishing
features of large vs. small
deposits will also
be considered.
3. A comparison
of gold
deposits in the
Abitibi
(Canada) and
Eastern
Goldfields
FRANÇOIS ROBERT
(SEG 1991 F)
(Australia) Archean greenstone terranes
This presentation will compare and
contrast the geology, evolution, and
gold deposits in these two well-endowed
gold provinces.
4. Geology and setting of gold
deposits of the north Carlin trend,
Nevada
This talk provides a review of the
geologic architecture and evolution of
the north Carlin trend, and of the
nature, timing, and structural controls
of Carlin-type gold mineralization in
that district.
A travel schedule for the 2004 lectures
is not determined at this point.
However, François will be available for
lectures at Australian and possibly
southeast Asian universities in the first
part of the year. He will present lectures
in other parts of the world throughout
the year as he travels between Australia
and Canada.
