Abstract The Zagros orogen records the closure of the Neotethys Ocean by northward subduction of the oceanic slab beneath the Iranian plate. Northwestern Iran has undergone episodic volcanism since the Eocene, due to a shift of tectonic regimes from subduction to collision and post‐collisional extension, although the dynamics responsible for such ...

Abstract Seismic anisotropy is observed in the lowermost few hundred kilometers of the mantle. This anisotropy likely signifies strong deformation, possibly caused by mantle flow interacting with the edges of Large Low‐Shear‐Velocity Provinces (LLSVPs) or by the ascent of mantle plumes originating near these regions.

Abstract In the southwest USA, the Colorado Plateau is encircled by Late Cenozoic volcanic fields, most of which have eruptive histories that are marginally constrained. Establishing the spatiotemporal evolution of these volcanic fields is key for quantifying volcanic hazards and understanding magma genesis.

Determining crustal strain rates with a spaceborne geodynamics ranging system. 2: Station coordinate analysis [PDF]
The use of a spaceborne geodynamics ranging system for determining crustal strain rates is analyzed. The use of site coordinates rather than intersite baseline distances for the strain rate determinations is emphasized.

Abstract New helium isotope data for basalt glasses from the Gulf of Tadjoura and Gulf of Aden reveal a mantle plume signal that has 3He/4He up to 17 RA. In the Gulf of Aden, plume helium is detectable ∼380 km from the Afar triple junction, up to the Shukra El Sheik Fracture Zone along the West Sheba Ridge, but not beyond.

Soil temperature extrema recovery rates after precipitation cooling [PDF]
From a one dimensional view of temperature alone variations at the Earth's surface manifest themselves in two cyclic patterns of diurnal and annual periods, due principally to the effects of diurnal and seasonal changes in solar heating as well as gains ...
