Using impact exsolution to link the Chicxulub collision and Deccan volcanism [PDF]
arXiv, 2017 Observations suggest that impactors and volcanism are connected, but the mechanism that links these events is unknown. This research proposes the impact exsolution hypothesis to explain how planetary scale collisions trigger volcanism. This hypothesis says that when large objects such as asteroids or comets hit planets, they generate seismic waves that

Water Planets in the Habitable Zone: Atmospheric Chemistry, Observable Features, and the case of Kepler-62e and -62f [PDF]
, 2013 Planets composed of large quantities of water that reside in the habitable zone are expected to have distinct geophysics and geochemistry of their surfaces and atmospheres. We explore these properties motivated by two key questions: whether such planets could provide habitable conditions and whether they exhibit discernable spectral features that ...

A review of multiscale numerical modeling of rock mechanics and rock engineering
Deep Underground Science and Engineering, EarlyView.Multiscale numerical methods of rock mechanics and rock engineering are reviewed, and the review results show that more attention should be paid to the development of an advanced constitutive model in addition to numerical techniques themselves. Abstract Rock is geometrically and mechanically multiscale in nature, and the traditional phenomenological ...
