The Urey ratio describes the contribution of internal heat production to planetary‐scale
energy balance, and knowing this thermal budget for Earth is essential to understand its …

Sparse seismic instrumentation in the oceans limits our understanding of deep Earth
dynamics and submarine earthquakes. Distributed acoustic sensing (DAS), an emerging …

This paper presents the first comprehensive major and trace element data for∼ 130 abyssal
peridotite samples from the Pacific and Indian ocean ridge–transform systems. The data …

Seismic imaging as a tool to understand the structure and, perhaps, the dynamics of the
planet at depth involves the spatially resolved, combined study of wave velocities and …

Plate tectonic theory was developed 50 years ago and underpins most of our understanding
of Earth's evolution. The theory explains observations of magnetic lineations on the seafloor …

We investigate seismic wave velocity reduction resulting from the presence of partial melt in
the upper mantle. The amount of shear and bulk modulus reduction produced by the …

In this section the contribution of CPO to seismic anisotropy in the deep Earth with cases of
olivine and the role of melt is illustrated. The CPO in rocks of upper-mantle origin is now well …

We present partial melting experiments at 2–3 GPa on a basaltic pyroxenite (G2) similar in
composition to typical oceanic crust. The 3.0 GPa solidus is located at 1310±12° C and the …

Microsporidia are obligate intracellular parasites of several eukaryotes. They have a highly
complex and unique infection apparatus but otherwise appear structurally simple …
