Abstract: Abstract Arc-basaltic melts of typical hydration state (≥ 2 wt% H2O) are buoyant relative to all common crustal igneous rock types and may pass adiabatically from a mantle source through continental crust directly to shallow depths… read more here.

Abstract: Abstract Detrital zircon geochronology is a powerful tool for investigating sedimentary provenance, but U-Pb zircon ages alone cannot distinguish between source terranes with similar age signatures. We integrate recent developments in petrochronology with sedimentary provenance… read more here.

DOI: 10.1016/j.jngse.2018.01.021
Abstract: Abstract Small-scale structures and tectonic stress are known to affect the production of coalbed methane. Ultrasonic borehole image logging (UBI) can be used to identify fractures and breakout zones around the wellbore and to analyze… read more here.

DOI: 10.1016/j.jseaes.2016.12.023
Abstract: Abstract The tectonic stress field in the middle-upper crust is closely related to the structure and rheology of the lithosphere. To determine the stress field in the deep crust, we inversed the focal mechanism solutions… read more here.

DOI: 10.1130/g47604.1
Abstract: Saucer-shaped sills are common in sedimentary basins worldwide. The saucer shape relates to asymmetric sill-tip stress distributions during intrusion caused by bending of the overburden. Most saucer-shaped sill models are constructed using a magma-analogue excess… read more here.
