The concentration and distribution of water in the Earth has influenced its evolution
throughout its history. Even at the trace levels contained in the planet's deep interior (mantle …

We analyze peridotites from a wide range of tectonic settings to investigate relationships
between olivine crystallographic preferred orientation (CPO) and deformation conditions in …

Orthopyroxene is the second most abundant mineral in the upper mantle and, like olivine,
can form crystallographic preferred orientations (CPO) during mantle deformation that may …

This chapter reviews the effects of source heterogeneities, melt‐rock reactions, and
intracrustal differentiation on magma chemistry across mid‐ocean ridges, intraplate settings …

Xenoliths play a crucial role in interpretation of mantle deformation and geochemistry. The
classic work of Mercier and Nicolas (1975) introduced the concept of the peridotite …

Sheared peridotites from the Kaapvaal craton may be broadly divided into two types:(1) high
T and refertilized and (2) low T and highly depleted, which equilibrated at conditions lying …

The influence of pyroxene on the rheology of peridotite is critical for understanding the
dynamics of the upper mantle. Intragranular deformation of each phase is often assumed to …

Seismic anisotropy arises in the upper mantle due to the alignment of olivine crystal lattices
and is often used to interpret mantle flow direction. Experiments on the evolution of olivine …

Melt-rock interaction, a general term describing various processes including cryptic and
modal metasomatism and melt-rock reaction, is the main process responsible for modifying …

We examine mid-lower crustal xenoliths erupted in Late Pleistocene to Holocene alkali
basalt at San Quintín, Baja California, Mexico to investigate the role of partial melt in deep …
