This collection of papers is based on a symposium held in 1987 at
the Interna tional Union of Geology and Geodesy Congress in
Vancouver, British Colum bia. The Symposium was planned as a
follow-up to a session at the 1984 Geo logical Society of America
Annual Meeting in Reno, Nevada, which dealt with the emplacement of
silicic lava domes. In both cases, emphasis was placed on the
physical and mechanical rather than chemical aspects of lava flow.
The IUGG Symposium consisted of two lecture sessions, a poster
session, and two discussion periods, and had 22 participants. The
contributions to this volume are all based on papers presented in
the various parts of the Sym posium. The motivation for studying
lava flow mechanics is both practical and scientific. Scientists
and government agencies seek to more effectively predict the
hazards associated with active lavas. Recovering mineral resources
found in lava flows and domes also requires an understanding of
their emplacement. From a more theoretical standpoint, petrologists
view lava studies as a way to directly observe the rheologic
consequences of mixing crystals, bubbles, and solid blocks of
country rock with silicate liquids. This information can then be
used to constrain processes occurring in the concealed conduits,
dikes, and chambers that feed flows and domes on the surface."
