Neutron scattering in earth sciences by Hans Rudolf Wenk
//
While earth science users are still a small minority, neutron scattering has nevertheless
contributed valuable information on geological materials for well over half a century.
Important applications have been in crystallography (e.g. atomic positions of hydrogen and
Al-Si ordering in feldspars and zeolites, Mn-Fe-Ti distribution in oxides), magnetic structures,
mineral physics at non-ambient conditions and investigations of anisotropy and residual strain
in structural geology and rock mechanics. Applications range from structure determinations of
large single crystals, to powder refi nements and short-range order determination in amorphous
materials. Zeolites, feldspars, magnetite, carbonates, ice, clathrates are just some of the
minerals where knowledge has greatly been augmented by neutron scattering experiments. Yet
relatively few researchers in earth sciences are taking advantage of the unique opportunities
provided by modern neutron facilities. The goal of this volume, and the associated short course
by the Mineralogical Society of America held December 7-9 in Emeryville/Berkeley CA, is
to attract new users to this fi eld and introduce them to the wide range of applications. As the
following chapters will illustrate neutron scattering offers unique opportunities to quantify
properties of earth materials and processes.
