The Earth can be viewed as a massive heat engine, with various energy sources and sinks.
Insights into its evolution can be obtained by quantifying the various energy contributions in …

The Western Pacific Triangular Zone (WPTZ) is the frontier of a future supercontinent to be
formed at 250 Ma after present. The WPTZ is characterized by double-sided subduction …

Enlarged and fully updated, this new edition takes into account the considerable
experimental and theoretical progress recently made in the field. Introduction to the Physics …

Genetic analyses of permafrost and temperate sediments reveal that plant and animal DNA
may be preserved for long periods, even in the absence of obvious macrofossils. In Siberia …

A new model of whole mantle P-wave tomography is determined with a novel approach. A
grid parameterization instead of blocks and spherical harmonics is adopted to express the …

A model of three-dimensional shear wave velocity variations in the mantle reveals a tilted
low velocity anomaly extending from the core-mantle boundary (CMB) region beneath the …

Despite immense progress in imaging seismic velocity anomalies in the mantle over the past
15 years, we still know relatively little about their physical cause. One way to shed some light …

A series of computer simulations of the Earth's dynamo illustrates how the thermal structure
of the lowermost mantle might affect convection and magnetic-field generation in the fluid …

Even a cursory historical look at the development of geology reveals that the cooling of the
Earth has always been a central issue (Birch, 1965; Fourier, 1824; Holmes, 1915; Joly …

We measured the spin state of iron in ferropericlase (Mg0. 83Fe0. 17) O at high pressure
and found a high-spin to low-spin transition occurring in the 60-to 70-gigapascal pressure …
