Injuries in deep time: interpreting competitive behaviours in extinct reptiles via palaeopathology
ABSTRACT For over a century, palaeopathology has been used as a tool for understanding evolution, disease in past communities and populations, and to interpret behaviour of extinct taxa. Physical traumas in particular have frequently been the justification for interpretations about aggressive and even competitive behaviours in extinct taxa.

Application of mineralogical, petrological and geochemical tools for evaluating the palaeohdrogeological evolution of the PADAMOT study sites [PDF]
The role of Work Package (WP) 2 of the PADAMOT project – ‘Palaeohydrogeological Data Measurements’ - has been to study late-stage fracture mineral and water samples from groundwater systems in Spain, Sweden, United Kingdom and the Czech Republic, with ...

The present study uses the Modified Mohr‐Coulomb true‐triaxial failure criterion (MMC_TT), which predicts the strength of rock better than the MGC criterion in laboratory true‐triaxial tests to overcome the limitations. Moreover, based on the data from previously published five vertical wells in the Krishna‐Godavari basin (K‐G basin), an empirical ...

Study on Mine Earthquake Prediction Based on Numerical Simulation of Rock Fracture Evolution
The deformation and instability of overlying strata is the root cause of roof dynamic disasters. Therefore, it is necessary to study the geomechanical behavior of overlying strata and the evolution law of three‐dimensional fracture morphology for ...

Catastrophic ice lake collapse in Aram Chaos, Mars
Hesperian chaotic terrains have been recognized as the source of outflow channels formed by catastrophic outflows. Four main scenarios have been proposed for the formation of chaotic terrains that involve different amounts of water and single or multiple

Evidence for an impact-induced biosphere from the δ34S signature of sulphides in the Rochechouart impact structure, France [PDF]
The highly eroded 23 km diameter Rochechouart impact structure, France, has extensive evidence for post-impact hydrothermal alteration and sulphide mineralization.

Blasting effects of cross‐fault deep‐buried excavation on adjacent existing tunnel stability
Based on the theoretical analysis of cylindrical wave propagation in a deep rock mass in the fault with a filling layer, the calculation method of peak particle velocity caused by wave propagation in the existing tunnel is established. The viscoelastic characteristics of a rock mass are examined in the analysis.
