Abstract The fossil rift in the North Pyrenean Zone, which underwent high temperature‐low pressure metamorphism and alkaline magmatism during Early Cretaceous hyperextension, was studied to explore geothermal regime at time of rifting. In this work, we combined Raman lab analysis thermal numerical modelling shed light on distribution gradients across inverted hyperextended Mauléon basin Albian Cenomanian time, its period active extension. Data were acquired from a set 155 samples densely...
Although digitized, geological maps have poorly evolved since their inception and still retain the constraints imposed by printing: heterogeneity between map sheets, limited point data, challenging update procedure that remains essentially nonexistent.The of also complicates integration to Information System. Maps, based on rules concepts over time, are no longer suited precision required database structures. As models evolve in geology together with scientific knowledge, choice...
Abstract Deformation processes related to early stages of collisional belts, especially the inversion rifted systems remain poorly constrained, partly because evidence these is usually obliterated during subsequent collision. The Pyrenean belt resulting from a Cretaceous hyperextended margin associated with high‐temperature and low‐pressure metamorphism in Internal Metamorphic Zone (IMZ), good example for studying stage orogenic deformation. This study focused on Eastern Pyrenees where...
The temporal dimension is an inherent component of geology. In this regard, traditional geological maps can represent a few events, yet they hardly account for the entire complex rock history whether sedimentary, crystalline or volcanic. Here, using RGF research program (French Geological Reference platform) we propose new methodology based on digital technology and French historical collection 1:50 000-scale maps. This innovative approach consists describing, organizing hierarchizing series...
<p>Examples of fossil and present-day passive margins resulting from mantle exhumation at the ocean–continent transition appear to have developed under conditions high heat flow. The pattern geothermal gradients along these hyperextended time rifting is interest for exploration petroleum resources, but difficult access. rift in North Pyrenean Zone, which underwent temperature–low pressure metamorphism alkaline magmatism during Early Cretaceous...
<p>The event geological maps consist in innovative numerical that were just designed and produced for the first time, as part of RGF (“French Geological Referential”) mapping program Pyrenees. Rocks acquire their mineralogical, structural textural characteristics through a complex history reflecting successive stages transformation (i.e. metamorphism, deformation, alteration…), so called “geological events”....
