Direct dating of brittle structures is challenging, especially absolute dating of diagenesis followed by a series of superimposed brittle deformation events. We report 22 calcite U-Pb ages from tec ...

Syn-Faulting Calcite Ages: Constraint for the Late Mesozoic Deformation of the Ningzhen Mountain, Eastern China
It is difficult to date a brittle fault because of the absence of effective dating methods. Recently, calcite U-Pb dating has drawn the attention of many researchers and has been successfully applied
Vein calcite dating reveals Pyrenean orogen as cause of Paleogene deformation in southern England
An improved method of U–Pb dating of vein calcite formed during deformation is used to determine the age and cause of folding along the south coast of England. Fractures arising from folding of Late
Quantifying deformation processes in the SE Pyrenees using U–Pb dating of fracture-filling calcites
It is difficult to quantify the timing of the deformation processes in brittle fold–thrust belts because minerals suitable for dating and well-preserved growth strata sediments are scarce or absent.
When did the Pyrenean shortening end? Insight from U–Pb geochronology of syn‐faulting calcite (Corbières area, France)
Absolute dating helps to define the age and duration of orogen building. Here we present new U–Pb ages of syn‐faulting calcites collected in the northern foreland basin of the Pyrenees. The studied
In situ U-Pb dating of hydrothermal diagenesis in tectonically controlled fracturing in the Upper Cretaceous Bekhme Formation, Kurdistan Region-Iraq
ABSTRACT This study concerns the absolute LA ICP-MS U-Pb dating of hydrothermal cementation, particularly in tectonically controlled fractures filling saddle dolomites and blocky calcites in the
U-Pb dating of calcite veins reveals complex stress evolution and thrust sequence in the Bighorn Basin, Wyoming, USA
We report U-Pb absolute ages of calcite cements from a diffuse vein network documented in the Bighorn Basin (Wyoming, USA), where distinct systematic vein sets developed at the front of the

Directly dating geologic events: U‐Pb dating of carbonates
Carbonates are ubiquitous, forming in a variety of settings including caves, soils, the oceans, during burial from hydrothermal fluids, and along faults. U‐Pb dating of carbonates is applicable to
U-Th dating of striated fault planes
Direct dating of brittle fault activity is of fundamental importance to tectonic reconstructions and paleoseismic studies. One way to address this issue is by constraining the timing of fault

Constraining the timing of brittle faulting is critical in understanding crustal deformation and fluid flow, but many regional-scale fault systems lack readily available techniques to provide
The dating of shallow faults in the Earth's crust
TLDR
A method of characterizing the clay populations in fault gouge, using X-ray modelling, combined with sample encapsulation, is presented and it is shown how it can be used to date near-surface fault activity reliably.
Linking hematite (U-Th)/He dating with the microtextural record of seismicity in the Wasatch fault damage zone, Utah, USA
Techniques directly dating fault slip are few, limiting the ability to interpret the rock record of seismicity. Hematite is commonly found in fault zones, amenable to (U-Th)/He dating, and slip
