</TD><TD>With the advent of new neutron sources and advances in neutron
instrumentation, neutron scattering is finding increased applications to studies
of materials including Earth and Planetary materials. Compared with X-ray
scattering, the scattering power of neutrons does not scale with the number of
electrons in an element, and thus neutron scattering is more sensitive to light
elements and is powerful in distinguishing neighboring elements in the periodic
table. Moreover, since neutrons are highly penetrating, neutron scattering is
well suited for combining with sample environment cells (such as pressure,
temperature and magnetic field) for in-situ real-time studies. Important areas
of applications to geological problems include high-pressure mineral physics
(e.g., stability of hydrous minerals), crystallography (e.g., ionic
order/disorder and magnetic structures), geochemistry (e.g., isotope
fractionation and fluid-rock interactions in a confined space), petrology (e.g.,
glass/melt structure and microstructure of rocks) and structural geology (e.g.,
texture and stress/strain analysis). The aim of this session is to provide an
interdisciplinary forum to promote discussions on the current state of neutron
scattering applications to a broad range of geological problems (not limited to
those described above). Submissions are also welcome from beamline scientists to
introduce instrumental capabilities and data analysis methods to stimulate
discussions on new applications.</FONT></DIV>
