Making Maps on a Micrometer Scale
Geographic information system software, created for mapping cities and continents, works equally well with the minuscule layers and inclusions that record a crystal’s history.
New Insights into Continental Deformation in Northwestern Tibet
A new surface velocity map shows strain localized along major strike-slip features, suggesting the central Tibetan Plateau is not deforming as a fluid in response to gravitational collapse.
Harry W. Green II (1940–2017)
By keenly probing mantle rheology, interactions of deformations and phase transitions, and microscopic features, he made major contributions to petrology, mineralogy, and earthquake science.
Acoustic Monitoring of Inelastic Compaction in Porous Limestone
During triaxial compression experiments, acoustic monitoring reveals compaction localization in a high porosity limestone, accompanied by a significant decrease in P-wave velocity.
Diamond Impurities Reveal Water Deep Within the Mantle
A high-pressure form of ice, trapped within diamonds forged in the lower mantle, suggests that aqueous fluids reside deeper in Earth than we knew.
Images Suggest a Viral Role in Some Rock Formation
Viruses might have helped transform dense bacterial colonies into a type of sedimentary rock that is frequently associated with underground oil reserves.
What Happens Inside Rocks as They Fail?
An innovative technique provides micro-scale resolution on the three-dimensional evolution of damage within crystalline rocks that leads to fault nucleation.
Is the Lower Crust Convecting Beneath Mid-Ocean Ridges?
The first attempt to couple models of hydrothermal circulation and magmatic convection along fast-spreading ridges may explain the spacing of hydrothermal vent fields along the East Pacific Rise.
Peering into the Cracks
A recent article in Reviews of Geophysics combined mathematical modeling, fracture mechanics theory and engineering research data to provide new insights into a critical geological process.
