Ten questions driving the geological and planetary sciences were identified today in a new report by the National Research Council. Aimed at reflecting the major scientific issues facing earth science at the start of the 21st century, the questions represent where the field stands, how it arrived at this point, and where it may be headed.

 | The first direct evidence of how and when tectonic plates move into the deepest reaches of the Earth has been detailed in Nature. Scientists hope their description of how plates collide with one sliding below the other into the rocky mantle could potentially improve their ability to assess earthquake risks. ...> Full Article |
Earthquakes occurring at the edges of tectonic plates can trigger events at a distance and much later in time, according to a team of researchers reporting in today's (Jan. 31) issue of Nature. These doublet earthquakes may hold an underestimated hazard, but may also shed light on earthquake dynamics.

 | Zigzagging some 60,000 kilometers across the ocean floor, Earth's system of mid-ocean ridges plays a pivotal role in many workings of the planet: in plate-tectonic movements, heat flow from the interior, and the chemistry of rock, water and air. ...> Full Article |
 | New Theoretical Model Suggests Plate Tectonics May Be On-Again, Off-Again Process ...> Full Article |
 | Plate tectonics, the geologic process responsible for creating the Earth's continents, mountain ranges, and ocean basins, may be an on-again, off-again affair. Scientists have assumed that the shifting of crustal plates has been slow but continuous over most of the Earth's history, but a new study from researchers at the Carnegie Institution suggests that plate tectonics may have ground to a halt at least once in our planet's history--and may do so again. ...> Full Article |
New minerals include stornesite-(Y), chopinite and tassieite, all are extremely rare and represented only by microscopic samples.
