Earthquakes as Precursors of Ductile Shear Zones in the Dry and Strong Lower Crust [PDF]
, 2017 The rheology and the conditions for viscous flow of the dry granulite facies lower crust are still poorly understood. Viscous shearing in the dry and strong lower crust commonly localizes in pseudotachylyte veins, but the deformation mechanisms ...

APG: An Efficient Software Program for Amp-Pl Thermobarometry Based on Graphical Method [PDF]
Journal of Sciences, Islamic Republic of Iran, 2011 Geothermobarometry equations are based on thermodynamic principles and appear in single or multi-variant functions. The number of variants for a specific composition or reaction usually is reduced into 2 involving temperature (T) and pressure (P).

Lithospheric 3D gravity modelling using upper-mantle density constraints: Towards a characterization of the crustal configuration in the North Patagonian Massif area, Argentina [PDF]
, 2017 The North Patagonian Massif is an Argentinean plateau that has an average height of 1200 m and stands from 500 to 700 m above the neighboring areas. During Paleogene, it suffered a sudden uplift of more than 1200 m without noticeable internal deformation;

Rapid cooling and exhumation as a consequence of extension and crustal thinning:Inferences from the late Miocene to Pliocene Palu Metamorphic Complex, Sulawesi, Indonesia [PDF]
, 2017 Metamorphic complexes forming high mountains of 1.5–2 km in Western Sulawesi were previously considered to be Mesozoic or older basement of Gondwana crust. However, many of the metamorphic rocks are much younger than previously thought.
