Abstract
Abstract. The incorporation of water in nominally anhydrous minerals plays a crucial
role in many geodynamic processes and evolution of the Earth and affects the
physical and chemical properties of the main constituents of the Earth's
mantle. Technological advances now allow the transport properties of
minerals to be precisely measured under extreme conditions of pressure and
temperature (P and T) that closely mimic the P–T conditions throughout much of
the Earth's interior. This contribution provides an overview of the recent
progress in the experimental studies on the influence of water on physical
properties (i.e., diffusivity, electrical conductivity, thermal
conductivity, sound velocity, and rheology) of olivine, wadsleyite, and
ringwoodite together with their applications. In particular, consistency
among various experimental data is investigated, discrepancies are
evaluated, and confusions are clarified. With such progress in the
experimental determination of transport properties of major mantle minerals,
we can expect new insights into a broad range of geoscience problems. Many
unresolved issues around water inside Earth require an integrated approach
and concerted efforts from multiple disciplines.
