We present an approach to dating of carbonates using isotopic maps. The maps are divided into squares called virtual spots. For each virtual spot, statistical values (mean, uncertainty) are used to determine the age. The user can modify the size and location of the virtual spots and select those that give the most robust age. This approach, applied to high-spatial-resolution images, makes it possible for the first time to obtain satisfactory ages on maps as small as 100 µm x 100 µm.

We investigated the Vocontian Basin in SE of France to understand its tectonic evolution and its preservation of deformation as it is at the intersection between Alps and Pyrenees. By combining calcite U–Pb dating, burial modeling and Raman thermometry, we identified three major deformation phases from the Late Cretaceous to the Miocene. Our results highlight how brittle deformation, fluid circulation, and thermal gradients record the interplay of multiple mountain-building and rifting events.

This paper aims to illustrate how the timing and duration of contractional deformation associated with folding in orogenic forelands can be constrained by the dating of brittle mesostructures observed in folded strata. The study combines new and already published absolute ages of fractures to provide, for the first time, an educated discussion about the factors controlling the duration of the sequence of deformation encompassing layer-parallel shortening, fold growth, and late fold tightening.

This paper reports a multiproxy approach to reconstruct the depth, timing, and extent of the past fluid flow during the formation of a fold-and-thrust belt in the Northern Apennines, Italy. The unique combination of paleopiezometry and absolute dating returns the absolute timing of the sequence of deformation. Combined with burial models, this leads to predict the expected temperatures for fluid, highlighting a limited hydrothermal fluid flow we relate to the large-scale subsurface geometry.
