Surface hydration‐induced damage in tight oil‐bearing sandy conglomerate reservoirs
Deep Underground Science and Engineering, EarlyView.A series of techniques such as X‐ray diffraction, scanning electron microscopy, energy‐dispersive spectroscopy, conductivity tests, and infrared thermal imaging were used. The key findings are the identification of a two‐stage surface hydration process and the elucidation of the effects of various minerals and elements on the hydration process ...

Exercise in Active Tectonics: An Introduction to Earthquakes and Tectonic Geomorphology
Eos, Transactions American Geophysical Union, 1996 What should undergraduate tectonics students know about earthquakes? The thesis of Exercises in Active Tectonics is that they ought to have some familiarity with quantitative methods for determining earthquake size, location, repeat time, and effect on structures.

Deep Underground Science and Engineering, EarlyView.Seismic waves with tensile stress, high amplitude, and low frequency are most likely to trigger block instability and sliding. Blocks with a single sliding surface are more prone to movement than those with multiple constraints, and roof‐positioned blocks are especially vulnerable to slide.
