Ultra-high temperature metamorphism recorded in Fe-rich olivine-bearing migmatite from the Khondalite Belt, North China Craton
2018
International audience; We document the first occurrence of Fe‐rich olivine‐bearing migmatitic metapelite in the Khondalite Belt, North China Craton. Petrological analyses revealed two exotic assemblages of orthopyroxene+spinel+olivine and orthopyroxene+spinel+cordierite. Phase relation modelling suggests that these assemblages are diagnostic of ultra‐high temperature (UHT) metamorphism in the Fe‐rich system, with temperatures from 1,000 to 1,050°C at 0.6 GPa. U–Th–Pb SIMS analyses on zircon reveal a similar age of c. 1.92 Ga for the olivine‐bearing migmatite and an adjacent gabbronoritic intrusion that is therefore identified as the heat source for the UHT metamorphism. These results, coup…
Lagrangian matches between observations from aircraft, lidar and radar in an orographic warm conveyor belt
2020
Warm conveyor belts (WCBs) are important airstreams in extratropical cyclones, often leading to the formation of intense precipitation and the amplification of upper-level ridges. This study presents a case study that involves aircraft, lidar and radar observations in a WCB ascending from western Europe towards the Baltic Sea during the Hydrological Cycle in the Mediterranean Experiment (HyMeX) and T-NAWDEX-Falcon in October 2012, a preparatory campaign for the THORPEX North Atlantic Waveguide and Downstream Impact Experiment (T-NAWDEX). Trajectories were used to link different observations along the WCB, that is, to establish so-called Lagrangian matches between observations. To this aim, …
La sépulture à char de La Tène A ancienne des “Craises” à Molinons (Yonne)
2013
The study reports on a chariot tomb excavated in 1985 at Les Craises in Molinons (Yonne). Set in an adventitious position in the midst of a monument with three quadrangular enclosures, the grave was of an adult of undetermined sex. Despite later pillaging, the goods found in this aristocratic tomb permit a dating to the second quarter of the 5th century BC, and an unusual cultural attribution, on the frontier in the Parisian Basin between the Jura culture to the south and the Marne-Moselle culture to the north.
