The Mesozoic along-strike tectono-metamorphic segmentation of Longmen Shan (eastern Tibetan plateau) [PDF]

open access: yes, 2018
The Longmen Shan belt (eastern border of the Tibetan plateau) constitutes a tectonically active region as demonstrated by the occurrence of the unexpected 2008 Mw 7.9 Wenchuan and 2013 Mw 6.6 Lushan earthquakes in the central and southern parts of the ...

Mafic High‐Pressure Rocks Are Preferentially Exhumed From Warm Subduction Settings

open access: yesGeochemistry, Geophysics, Geosystems, 2018
The oceanic crust that enters a subduction zone is generally recycled to great depth. In rare and punctuated episodes, however, blueschists and eclogites derived from subducted oceanic crust are exhumed.

How large are departures from lithostatic pressure? Constraints from host-inclusion elasticity [PDF]

open access: yes, 2015
Minerals trapped as inclusions within other host minerals will develop non-lithostatic pressures during both prograde and retrograde metamorphism because of the differences between the thermo-elastic properties of the host and inclusion phases.

Petrology of blueschist facies metamorphic rocks of the Meliata Unit [PDF]

open access: yesActa Montanistica Slovaca, 1997
Meliata blueschists originated from basalts, limestones, pelites, psammitic and amphibolite facies basement rocks. Compositionally, the metabasalts have a geochemical signature mostly indicative of a transitional arc-MORB origin, but some mafic rocks ...

Mineralization of the Tuwu Porphyry Cu Deposit in Eastern Tianshan, NW China: Insights From In Situ Trace Elements of Chlorite and Pyrite

open access: yesFrontiers in Earth Science, 2021
The Tuwu porphyry copper deposit is located on the Dananhu-Haerlik island arc in eastern Tianshan, NW China. Based on geology, petrology, and in situ trace element studies of pyrite and chlorite, we redefined the characteristics of hydrothermal fluids ...
