Abstract Pelitic schists from Qingshuigou in the Northern Qilian Mountains of China contain mainly glaucophane, garnet, white mica, clinozoisite, chlorite and piemontite. Isotopic age dating these provides new constraints on formation high‐grade blueschists at Qingshuigou. White mica 40 Ar/ 39 Ar ages range 442.1 to 447.5 Ma (total fusion single grain) 445.7 453.9 (integrated concentrates). These (442.1–453.9 Ma) represent peak metamorphic or cooling during exhumation shortly after...

The western sector of the Qinling-Dabie orogenic belt plays a key role in both Late Jurassic to Early Cretaceous "Yanshanian" intracontinental tectonics and Cenozoic lateral escape triggered by India-Asia collision. Taibai granite northern Qinling Mountains is located at westernmost tip Yanshanian belt. It consists multiple intrusions, constrained new U-Pb zircon ages (156 ± 3 Ma 124 1 Ma). Applying various geochronometers (40Ar/39Ar on hornblende, biotite K-feldspar, apatite fission-track,...
Abstract The Qinling Orogenic Belt was formed by long‐lived subduction and collision between the North South China blocks. Our 40 Ar/ 39 Ar geochronological data of amphibole, white mica, biotite reveal different exhumation cooling histories major units in (SQB), constraining multiple orogenic processes. Group started before 432 Ma, through about 500 °C during 432.3–405 followed rapid below 425 at 388.9 ± 1.1 Ma slow 300 333.3–329.5 Ma. A similar history Kuanping from 383 cooled 364.9 1.2...
Indentation of rigid blocks into rheologically weak orogens is generally associated with spatiotemporally variable vertical and lateral block extrusion. The European Eastern Southern Alps are a prime example microplate indentation, where most the deformation was accommodated north crustal indenter within Tauern Window. However, outside this window only broad late-stage exhumation pattern indented units as well itself known. In study we refine exhumational new (U–Th–Sm)/He fission-track...
Abstract The Diancang Shan metamorphic massif, the northwestern extension of Ailao Massif, is a typical complex situated along NW–SE-trending Shan–Red River shear zone. granitic and amphibolitic mylonites collected from sheared high-grade rocks were studied using petrographic electron-backscatter diffraction techniques. Sensitive high-resolution ion microprobe U–Pb dating zircon grains constrains timing shearing. Macro- microstructural textural analysis reveals intense plastic deformation...
We present a detailed case study of an exhumed continental strike-slip fault zone, the Ailao Shan-Red River (ASRR) to investigate how deformation promotes strain localization, and weak second phases fluids trigger rheological weakening during retrogression near ductile brittle transition exhumation. Along ASRR in Diancang Shan (DCS) metamorphic massif, high-temperature (D1) pervasively occurred shearing exhumation since late Oligocene. The microstructures textures are part or entirely...
We use two‐dimensional (2‐D) P‐T‐t modeling to constrain the thermal and rheological aspects of different scenarios for late Mesozoic Cenozoic tectonic evolution Eastern Alps, inferred from excellent data sets Tauern Window (TW). Models invoking subduction South Penninic (SP) oceanic lithosphere during thrusting subsequent erosion Austro‐Alpine (AA) upper plate nappe stack are inconsistent with observed within AA units. In these models, predictions peak conditions lower than observed. After...
