The Ninth International Conference on Basement Tectonics was held at the
Australian National University in Canberra 2-6 July 1990. The opening
keynote address was given by Prof. R.W.R. Rutland, Director of the
Bureau of Mineral Resources. Other keynote speakers were E.S.T.
O'Driscoll, an Australian consultant, and Prof P. Bankwitz, Central
Institute for Physics of the Earth, Potsdam, GDR. Technical sessions
were arranged by session conveners on the following five topic- i) The
structure of the Australian craton and cover basins; ii) Basement
structure of continental regions; iii) Structural patterns and mineral
deposits; iv) Techniques for analysing basement structures; v)
Structural patterns in oceanic crust. The arrangement of papers for this
Proceedings Volume has been simplified. Part 1 deals with Australia,
Part 2 with other areas and Part 3 lists the titles of all the papers
read at the conference. Abstracts of these papers are available in
Geological Society of Australia Abstracts No 26 and may be purchased for
$AI0 from the Geological Society of Australia Office, ANA House, 301
George Street, Sydney NSW 2000. Field trips to view aspects of the
Lachlan Fold Belt and the Sydney Basin were assisted by H.J. Harrington,
D. Branagan, D. Wyborn, B. Drummond and M.J. Rick d. A longer field
trip, aborted through low enrolments, was organized by H.J. Harrington
with assistance from W. Preiss, N. Cook, R. Glenn, A. Grady, and P.
James; this assistance is gratefully acknowledged.
