Evolution of midplate hotspot swells: Numerical solutions [PDF]

open access: yes
The evolution of midplate hotspot swells on an oceanic plate moving over a hot, upwelling mantle plume is numerically simulated. The plume supplies a Gaussian-shaped thermal perturbation and thermally-induced dynamic support.

Analogue Experiments of Subduction vs. Collision Processes: Insights for the Iranian Tectonics

open access: yes, 2005
We investigate, using laboratory experiments, the behavior of subduction-collision transition. These experiments help understanding of the tectonics at the transition between the Zagros collision ranges and the Makran emerged accretionary prism in south ...

Oceanic structures of the Earth and the North Depression of Mars: A comparison of the formation mechanisms [PDF]

open access: yes
The system of contemporary oceans on Earth and the North Depression of Mars are quasi-symmetrical in reference to the centers of of the hemispheres. Both systems had been formed over the common megacycle of evolution of planets and their origin is likely

Pre-terrestrial origin of rust in the Nakhla meteorite [PDF]

open access: yes
The authors present quantative elemental compositions and summarize textural evidence for the pre-terrestrial origin of rust on the Nakhla meteorite. The material in question is called 'rust' because its phase composition remains unknown.

Joint document concerning geological studies from 1971 - 1975 [PDF]

open access: yes
In 1971, a joint Soviet-Americam Working Group on Remote Sensing of the Natural Environment was established. It was organized into a number of discipline panels, one of which was on geology. Membership on this panel came from the Geological Survey of the
