Seismic travel-time tomography of the mantle under SE Asia reveals patterns of subduction-
related seismic P-wave velocity anomalies that are of great value in hel** to understand …

Nitric oxide (NO) is a simple gas with free radical chemical properties, but itis often confused
with the chemically distinct nitrous oxide, N2O, which is used as an anesthetic and is …

Earth's mantle has a two-layered structure, with the upper and lower mantle domains
separated by a seismic discontinuity at about 660 km (refs.,). The extent of mass transfer …

Trace-element data for mid-ocean ridge basalts (MORBs) and ocean island basalts (OIB)
are used to formulate chemical systematics for oceanic basalts. The data suggest that the …

The geochemical and geodynamical parameters that may influence the composition of
island-arc basalts (IAB's) are evaluated. Systematic correlations amongst high-field strength …

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 …

We combine a new, large data set of surface wave phase anomalies, long‐period
waveforms, and body wave travel times to construct a three‐dimensional model of the …

The bulk chemical composition of the Upper Mantle (“pyrolite”) is derived from experimental
and petrological studies of the complementary relationships between basaltic magmas and …

The P wave velocity structure beneath the Western Pacific is found from the International
Seismological Center first arrival data. Special attention was paid to the deep structure …

We made a region‐by‐region examination of subducted slab images along the circum‐
Pacific for some of the recent global mantle tomographic models, specifically for two high …
