Brittle Structural Control and Fluid Progress of the Jinqingding Gold Deposit: Implications for Epizonal Gold Mineralization

open access: yesActa Geologica Sinica - English Edition, Volume 100, Issue 3, Page 781-794, June 2026.
High‐grade orebodies are controlled by stress field with σ1 oriented NE‐SW during the main mineralization stage.Inferred NEE‐trending strike‐slip fault control another orebody distribution. ABSTRACT The Jinqingding gold deposit in eastern Jiaodong is a significant gold mineralization within the Muping–Rushan metallogenic belt.

Fluid-assisted granulite metamorphism: a continental journey

open access: yes, 2012
Lower crustal granulites, which constitute the base of all continents, belong to two series: high-pressure granulites generated by crustal thickening (subduction) and (ultra)high-temperature granulites associated with crustal extension.

Jadeite in Continental Subduction: Its Preservation, Breakdown and Pseudomorphic Replacement in Erzgebirge UHP Gneisses

open access: yesJournal of Metamorphic Geology, Volume 44, Issue 5, Page 376-393, June 2026.
ABSTRACT The absence of jadeite in regions where subduction of continental crust has been documented by other high‐pressure (HP) or ultrahigh‐pressure (UHP) minerals is striking. This study presents only the second discovery of jadeite in the crystalline rocks of the Erzgebirge, a region known for its occurrences of microdiamond, coesite and omphacite ...

Effect of temperature, pressure and chemical composition on the electrical conductivity of granulite and geophysical implications

open access: yes, 2019
Electrical conductivities of three granulite samples (main minerals: plagioclase, quartz, and biotite) with different chemical compositions (W-B, the weight percent of Fe2O3 = 5.49, 8.75, and 14.79 wt%) were researched using a complex impedance ...

Rift basins of the late phanerozoic of Africa: regional patterns and conceptual development aspects

open access: yesИзвестия высших учебных заведений: Геология и разведка
Background. This work substantiates the dependence of the development modes of rift basins of the Late Phanerozoic of Afro-Arabia on the size and age of the Lower crust structures (granulite belts) in which they were laid.

Interior Rifting Coupled With Peripheral Subduction in the Rodinia Supercontinent: New Insights From the Tarim Craton

open access: yesGeochemistry, Geophysics, Geosystems, Volume 27, Issue 5, May 2026.
Abstract After assembly, supercontinents are shaped by internal rifting and peripheral subduction. However, the geodynamic relationship between these two processes and their respective contributions to supercontinent breakup remain poorly understood.

Position of Saxonian granulite within the frame of European Variscides [PDF]

open access: yes, 2012
The Saxonian Granulite Massif (the type granulite locality) is situated in the northwestern part of Bohemian Massif. It is an antiform with dome structure, which came to the surface from below SaxoThuringian Paleozoic units.

Autocorrelation Seismic Imaging of Northern Taiwan Using Ambient Noise Data

open access: yesJournal of Geophysical Research: Solid Earth, Volume 131, Issue 5, May 2026.
Abstract Over the past few million years, northern Taiwan records a tectonic history of subduction to arc–continent collision followed by post‐collisional collapse. This evolution motivates constraints on crustal structure, including crustal layering and thickness.

Thermal structure of the crust during granulite metamorphism: petrological speculations and geodynamic implications

open access: yes, 1998
P(論文)It is shown on a basis of generalization of lateral and vertical distribution of P-T parameters in granulite-gneiss belts of various ages that the thermal gradient within the lower crust during granulite metamorphism is rather low, ca. 5-10℃/km. Two
