Largest Delta Plain in Earth’s History Discovered in Arctic
If this Triassic period delta existed today, its footprint would equal about 1% of all land on Earth.
Project VoiLA: Volatile Recycling in the Lesser Antilles
Deep water cycle studies have largely focused on subduction of lithosphere formed at fast spreading ridges. However, oceanic plates are more likely to become hydrated as spreading rate decreases.
Seismic Anisotropy Due to a Compositionally Layered Mantle
Investigating the role of layered rocks and compositional banding on mineral scale in generating seismic anisotropy in the mantle.
Real Time Probing of Shale Cracks in Double Torsion Experiments
Imaging crack propagation in shales using twin optical cameras and fast X-ray radiograph acquisition.
Thermal Signature of Martian River Deposits Suggests Cementation
Are there indications of extended aqueous processes beyond the period of widespread fluvial activity on Mars?
Self-Guided Tour of the Geology in D. C. Buildings
The architecture of the nation’s capital reveals a secret geologic history—take a walking tour to spot the interesting fossils and minerals in the stones used to build the halls of power.
In a Submarine Trough, Permeable Rocks May Lead to Quakes
In Japan’s submarine Nankai Trough, rock permeability is much higher when measured at larger scales, likely because of big fractures and faults that are not captured at small scales.
A More Detailed Look at Earth’s Most Poorly Understood Crust
The second-generation Antarctic Digital Magnetic Anomaly Project offers a powerful new tool for probing the structure and evolution of the southernmost continent’s lithosphere.
Mercury Mission Will Map Morphology and Measure Magnetics
BepiColombo may launch as early as this weekend. It seeks to unravel the mysteries of Mercury’s geologic and magnetic past and map the small planet’s cratered surface.
