The Cenozoic Song Hong–Yinggehai Basin in the South China Sea contains a large volume of sediment that has been used previous studies, together with regional geomorphology, to argue for existence palaeodrainage system connected eastern Tibet Sea. To test this and understand significance volumes deposited Basin, study compared erosion histories source regions during two main stages basin evolution spanning active rifting subsidence (30–15.5 Ma) postrift sedimentation (15.5 Ma present)....
In northern Peru, a 500 km long regional balanced section has been constructed across the eastern Andean wedge, using fieldwork, industrial seismic sections, and wells. The structure is characterized by thin-skinned thrust system involving Eastern Cordillera (EC), sub-Andean zone (SAZ), Marañón foredeep. SAZ easternmost foredeep development of driven combination two structural events. Permian faults had reactivated to form basement duplex underlying At same time Triassic-Jurassic extensional...
Abstract Constraining the way in which continental deformation is accommodated time and space essential to reconcile past plate movements with geological observations. Kinematic reconstructions of Iberia‐Europe boundary are still debated. Here we focus on an inverted Mesozoic rift basin, Cameros part Iberian chain. We use a combination detrital low‐temperature thermochronological techniques define time‐temperature evolution basin from rifting Cenozoic collision. Zircon fission‐track analyses...
Zircon and apatite fission track (ZFT AFT) (U‐Th)/He, 40 Ar/ 39 Ar hornblende, U‐Pb zircon ages from the granites of Tinos Island in Aegean Sea, Greece, suggest, together with published ZFT data, that there are three extensional detachments on Tinos.

The timing and source of deformation responsible for formation the Sierra Madre de Chiapas (south Mexico) are unclear. To address this, apatite fission track U‐Th‐He thermochronometry, combined with zircon U‐Pb dating, were performed on bedrock sedimentary samples to discern exhumation identify sediment areas. results show that Paleocene–Eocene terrigenous units outcropping at northern section mostly derived from Grenville (∼1 Ga) basement whereas internal sections chain yield mainly Permian...
The combination of zircon U-Pb geochronology, trace element geochemistry and Hf isotopes have become an extremely popular tool for provenance studies paleogeographic reconstructions. Here, we present integrated study U-Pb-Hf isotopic geochemical constraints from two basement complexes in western Luzon, Philippines. Basement rocks these areas offer insights into the geologic tectonic development northern Philippines its correlation with adjacent southeast Asia. We also include Mesozoic Taiwan...
Structural, thermochronological and metamorphic data are used to elucidate the tectonic nature evolution of ductile extensional Messaria shear zone associated brittle Fanari detachment faults, which exhumed their footwall from mid-crustal depths on island Ikaria in Aegean. Thermobarometric indicate that formed at 350–>400 °C 3–4 kbar (i.e. a depth c . 15 km). Normal faulting was accompanied by intrusion two granites, together with thermobarometric relatively high thermal field gradient...
We discuss the drivers of Pyrenean post-orogenic exhumation, including drainage migration, flexural rebound and tectonic reactivation.We provide new low-temperature thermochronological data inverse thermal modeling from both hinterland foreland western Pyrenees. Our ages range 6.6 to 61.4 Ma reveal a Late Miocene exhumation phase in several massifs. The contrasting histories define domain focused Pyrenees that coincides with present-day extensional tectonics region north Axial Zone. Based on...
Terra Nova, 23, 116–126, 2011 Abstract New apatite fission track (AFT) and (U‐Th)/He ages from the Argentera–Mercantour External Crystalline Massif of SW Alps document an exhumation history along transcurrent dextral faults. Significant AFT age differences across strikes main faults have been obtained NE (12.9 Ma) to (5.2 are linked vertical uplifts these right‐lateral transpressional structures. Such segmentation is not observed in AHe ages. preserved younger (4–5 on eastern hangingwall...
Abstract New thermochronometric data provide evidence for an along‐strike diachronous building of the Andes in north‐central Chile (28.5–32°S). Geochronological (U‐Pb zircon) and thermochronological (apatite fission track (U‐Th)/He) analyses rock units were obtained west‐to‐east transects across western topographic front. Thermal models indicate that area west front was little exhumed since approximately 45 Ma. To east front, Main Cordillera shows both latitudinal longitudinal differences...
Abstract We apply low-temperature thermochronology, Rb/Sr geochronology, petrological data, and structural mapping to constrain the timing kinematics of Ios metamorphic core complex. Top-to-north extension in lower plate Headland Shear Zone was active at 18–19 Ma under conditions 475–610 °C 0.65–1.1 GPa. The South Cyclades Zone/Ios Detachment Fault (SCSZ/IDF) system shows top-to-south extensional shear c. 19 380–550 °C, with local top-to-north bands. Extensional above SCSZ/IDF is dominantly...
Abstract: In Peru, the western edge of 4.5 km high Western Cordillera is cut by a >3 deep canyon. To understand incision Cotahuasi–Ocoña River and regional uplift history this orogenic plateau capped volcanic rocks, 26 crystalline rock samples were collected for low-temperature thermochronology from vertical profiles parallel perpendicular to Rock cooling histories confirm that most denudation had occurred prior 24 Ma but peaked after c . 14–9 in response rapid surface uplift. The abrupt...
Abstract The effect of mean precipitation rate on erosion is debated. Three hypotheses may explain why the current and runoff be spatially uncorrelated: (1) topography has reached a steady state for which pattern determined by uplift pattern; (2) only depends weakly runoff; or (3) studied catchments are experiencing different transient adjustments to climate variations. In Chilean Andes, between 27°S 39°S, annual rates increase southwards from 0.01 2.6 m −1 but catchment averaged decadal...
Abstract The Betic‐Rif orogen is a key region to understand the evolution of plate boundary between Africa and Iberia/Europe. This study focuses on Flysch Complex, which considered sedimentary cover domain originally positioned Iberian Alboran margins. Based stratigraphic depositional constraints, evidence for salt tectonics, combined with new apatite fission‐tracks (AFT) (U‐Th‐Sm)/He ages from Complex Subbetic Zone, we propose geodynamic interpretation formation Betic Cordillera, accounting...
Abstract Supergene copper mineralisation (SCM) processes occur during the unroofing of porphyry deposits. However, geomorphological stage which main occurs is still under debate. Here, we present 24 new thermochronological data from Cenozoic intrusives and compare them with evolution supergene Centinela Mining District in Atacama Desert. Our results indicate a two‐step cooling path: rapid Late Eocene exhumation followed by slow denudation. Previously published ages cluster after Upper...
Abstract Mountain building in the Al-Hajar Mountains (NE Oman) occurred during two major shortening stages, related to convergence between Africa–Arabia and Eurasia, separated by nearly 30 Ma of tectonic quiescence. Most was accommodated Late Cretaceous, when northward subduction Neo-Tethys Ocean followed ophiolites obduction on top former Mesozoic margin. This event lasted until latest Santonian – early Campanian. Maastrichtian Eocene carbonates unconformably overlie eroded nappes seal...
