Cover Story: The image displays an aerial view of tension fractures in a Holocene pahoehoe lava flow at the southern end of Almannagjá, the western boundary fault of the main graben of the Thingvellir fissure swarm in Southwest Iceland. The (mostly) parallel fractures are oblique to the main direction of Almannagjá, giving rise to the observed en échelon fracture arrangement. The maximum opening of the fracture to the right of the white car is 12 m. Rock fractures control many of the most important dynamic processes in the Earth’s crust. Most rock fractures (and associated earthquakes) are comparatively small, while only a few are very large, resulting in poorly understood power or exponential size distributions. Using principles from statistical physics, fracture mechanics, and rock heterogeneity, an explanation is provided for these size distributions. View this paper

  • Nicola Mari,
  • Daniele Musumeci,
  • Luigi Ingaliso and
  • Francesco Vetere

The rock cycle, a cornerstone of geosciences, describes rock formation and transformation on Earth. However, this Earth-centric view overlooks the broader history of rock evolution across the cosmos, with two fundamental limitations: (i) Earth-centri...

Machine Learning for Reservoir Quality Prediction in Chlorite-Bearing Sandstone Reservoirs

  • Thomas E. Nichols,
  • Richard H. Worden,
  • James E. Houghton,
  • Joshua Griffiths,
  • Christian Brostrøm and
  • Allard W. Martinius

We have developed a generalisable machine learning framework for reservoir quality prediction in deeply buried clastic systems. Applied to the Lower Jurassic deltaic sandstones of the Tilje Formation (Halten Terrace, North Sea), the approach integrat...

The recently proposed concept of “precursory fingerprint” is a logical consequence of the commonsense statement that seismic structures are unique and that their expected preshock behaviors, including precursory phenomena, are also unique...
