Large Deformation Disaster Mechanism and Control Technique for Deep Roadway in Faulted Zone [PDF]
Frontiers in Earth Science, 2022 In order to study the mechanism and control technique of deep roadways in faulted zones, the 11-2 transport roadway of Guqiao coal mine in Huainan was taken as a case. The research roadway encountered two faults named F97 and F98 and suffered a severe large deformation disaster (including floor heaving, side cracking, steel arch bending, and section ...

Magnetic zones of Mars: Deformation‐controlled origin of magnetic anomalies [PDF]
Meteoritics & Planetary Science, 2009 Abstract— Intense magnetic anomalies over Martian surface suggest preservation of large volumes of very old crust (>3 Gyr) that formed in the presence of a global magnetic field. The global distribution of the magnetic intensities observed above the Martian crust suggests a division into three zones.

Geophysical Research Letters, 2022 AbstractThis work links mineral‐scale deformation mechanisms with structural evolution during subduction, providing examples showing how grain‐scale heterogeneities facilitated viscous creep in calcite at nominally seismogenic temperatures. Carbonates commonly enter subduction zones, either highly concentrated in irregularly distributed sediments or as
