The continental margin of southeast Brazil is elevated. Onshore Tertiary basins and Late Cretaceous/Paleogene intrusions are good evidence for post breakup tectono‐magmatic activity. To constrain the impact post‐rift reactivation on geological history area, we carried out a new thermochronological study. Apatite fission track ages range from 60.7 ± 1.9 Ma to 129.3 4.3 Ma, mean lengths 11.41 0.23 μ m 14.31 0.24 subset (U‐Th)/He 45.1 1.5 122.4 2.5 Ma. Results inverse thermal modeling generally...
Abstract A transformative advance in Earth science is the development of low‐temperature thermochronometry to date surface processes or quantify thermal evolution rocks through time. Grand challenges and new directions involve pushing boundaries these techniques decipher histories operative over seconds hundreds millions years, recent deep geologic time from perspective atoms mountain belts. Here we highlight innovation bedrock detrital fission track, (U–Th)/He, trapped charge...
Abstract The (U-Th)/He dating technique is an essential tool in Earth science research with diverse thermochronologic, geochronologic, and detrital applications. It now used a wide range of tectonic, structural, petrological, sedimentary, geomorphic, volcanological, planetary studies. While some circumstances the interpretation data relatively straightforward, other cases it less so. In geologic contexts, individual analyses same mineral from single sample are expected to yield dates that...
Abstract The field of (U-Th)/He geochronology and thermochronology has grown enormously over the past ∼25 years. tool is applicable across much geologic time, new chronometers are under continuous development, method used in a diverse array studies. Consequently, technique rapidly expanding user base, labs being established worldwide. This presents both opportunities challenges. Currently there no universally agreedupon protocols for reporting measured data or derivatives. Nor standardized...
The impact of rift-related processes on tectonic and thermal evolution collisional orogens is poorly documented. Here, we study the northern Pyrenees, a region that has preserved geological record transition from rifting to collision. Using modeling new low-temperature thermochronological data, including fission track (U-Th)/He apatite zircon, propose temporal reconstruction inversion European rifted margin. Our data confirm related cooling started in Late Paleozoic-Triassic. Throughout...
The Litang fault system that crosses the Plateau, a low relief surface at high elevation (~4200–4800 m above sea level) is not affected by regional incision, provides opportunity to study exhumation related tectonics in SE Tibetan Plateau independently of erosion. Combining apatite and zircon fission track with (U-Th)/He thermochronologic data, we constrain cooling history footwall along two transects. Apatite ages range from 4 16 Ma, AHe 2 6 Ma, one age ~99 Ma. These data imply tectonic...
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...
ABSTRACT The incision history of the Three Rivers (Salween, Mekong, and Yangtze) region in Southeast Tibetan Plateau has been linked to both tectonic climatic controls. In this study, we report new apatite (U‐Th)/He fission‐track thermochronology data from >6,000‐m‐high Kawagebo massif, which forms edge high plateau on western flank steepened knickzone reach middle Mekong River valley. Thermal‐history modeling a thermochronological age‐elevation profile shows rapid cooling since ~1.5 Ma...
The late Neogene–Quaternary exhumation history of the European Alps is subject controversial findings and interpretations, with several thermochronological studies arguing for long‐term steady state rates, while others have pointed to Miocene–Pliocene pulses associated tectonic and/or climatic changes. Here, we perform inverse thermal‐kinematic modeling on dense data sets combining apatite fission track (AFT) from literature recently published (U‐Th‐Sm)/He (AHe) along upper Rhône valley (Aar...
The central Pyrenees experienced an episode of rapid exhumation in Late Eocene–Early Oligocene times. Erosional products shed from the range during this time were deposited large palaeovalleys southern flank Axial Zone, leading to significant sediment accumulation. A recent numerical modelling study post-orogenic and relief history Zone allowed us constrain valley-filling terms timing thickness conglomeratic deposits. This paper aims test these results for fold-and-thrust belt using apatite...
