A global review of earthquake rupture parameters reveals that deep earthquakes have larger fracture energies and may have different rupture mechanisms than shallower seismic events.Read More »Geochemistry, Mineralogy, Volcanology
Records from drill holes in the eastern equatorial Pacific indicate that Earth's orbital eccentricity played an important role in controlling climate as the planet warmed.Read More »
Estimates of crystallization temperatures from four eruptions in northern Iceland offer improved constraints on the mantle's temperature beneath this anomalous divergent plate boundary.Read More »
Chemicals released by two European nuclear fuel reprocessing plants, along with certain chlorofluorocarbons, are helping to constrain the speed and behavior of North Atlantic deep-ocean circulation.Read More »Planetary Sciences
The consistently shallow depths of the depressions scattered across Mercury's surface suggest their morphology is not determined by the thickness of a volatile-rich outer layer.Read More »Geology & Geophysics
New magnetic and gravity data suggest that the boundary between continental and oceanic crust lies beneath northern Bangladesh, along the line of an Early Cretaceous spreading center.Read More »Geology & Geophysics
A multidisciplinary model linking the sedimentary and tectonic histories of this structurally complex basin suggests that large amounts of extension occurred there between 20 and 9 million years ago.Read More »Geology & Geophysics
A review of the major features of the geomagnetic reversals preserved in Earth's rock record helps to answer the question, Which data could advance our understanding of these poorly described events?Read More »Planetary Sciences
The discovery of dense concentrations of recurring flowlike features in two Valles Marineris chasms could aid in the search for life and influence future exploration of the Red Planet.Read More »
A reinterpretation of structural and paleomagnetic data suggests that New Zealand's Alpine Fault accommodates a far greater percentage of geologically recent plate motion than previously thought.Read More »
