Crustal and uppermost mantle structure in southern Africa revealed from ambient noise and teleseismic tomography

S U M M A R Y Rayleigh wave phase velocity maps in southern Africa are obtained at periods from 6 to 40 s using seismic ambient noise tomography applied to data from the Southern Africa Seismic Experiment (SASE) deployed between 1997 and 1999. These phase velocity maps are combined with those from 45 to 143 s period which were determined previously using a two-planewave method by Li & Burke. In...

Peridotites Related to 4vesta: Deep Crustal Igneous Cumulates and Mantle

In advance of the arrival of the DAWN spacecraft at 4Vesta in 2011, it is useful to reassess our knowledge of the constitution and probable evolution of this ancient differentiated asteroid. It has been recognized for some time that the eucrite, diogenite and howardite meteorites likely represent samples from 4Vesta or from related Vestoids based upon the good match of reflectance spectra of th...

Seismic constraints on temperature of the Australian uppermost mantle

We derive estimates of temperature of the Australian continental mantle between 80 and 350 km depth from two published S-velocity models. Lithospheric temperatures range over about 1000 8C, with a large-scale correlation between temperature and tectonic age. In detail however, variations ranging from 200 to 700 8C occur within each tectonic province. At the current seismic resolution, strictly ...

Dynamic Earth: crustal and mantle heterogeneity*

The dynamic processes within the Earth leave their record in geophysical and geochemical variation about the general stratification with depth. A snapshot of current structure is provided by geophysical evidence, whereas geochemical information provides a perspective over the age of the Earth. The combination of information on the distribution of heterogeneity from geophysical and geochemical s...

Mobilizing aluminum in crustal and mantle fluids

Aluminum is a major rock-forming element, but its low solubility in H2O at upper crustal conditions has led to the assumption that it is effectively immobile during fluid–rock interaction in the deep crust and upper mantle. However, new experimental results on Al solubility in H2O–SiO2–NaCl fluids at high pressure and temperature challenge this view. The combined effects of temperature, pressur...
