Fluid inclusion formation during heat treatment of barremo-bedoulian flint: Archaeometric implications
Le site du Centre mobilisateur 10, situé au sud-est de l'agglomération de Lannemezan (Hautes-Pyrénées) et autrefois connu sous le nom de l'Arsenal, a fait l'objet en 2016 d'une fouille préventive réalisée par le bureau d'études Éveha, sous la responsabilité de V. Ropiot. D'un point de vue géographique, entre la Bigorre et le Comminges, ce...
Highlights • Mica generations are characterized by unique trace-element signatures. • Igneous lepidolite is the main host of W in the Beauvoir granite body. • Alteration of igneous micas can lead to economic W deposition. • Greisen micas can incorporate significant Sn, inhibiting cassiterite deposition.
In the Echassières district of the French Massif Central, occur several outstanding magmatic/hydrothermal systems enriched in strategic metals, such as the Beauvoir rare-metal granite. In this contribution we propose a systematic approach, based on mica trace chemistry, to decipher the different events leading to mineralization. Twelve groups...
A rescue excavation at the site of Centre mobilisateur 10, located in the south-east of the Lannemezan agglomeration (Hautes-Pyrénées) and otherwise known as the Arsenal, was carried out in 2016 by the Éveha team, under the leadership of V. Ropiot. From a geographic perspective, this sector, between Bigorre and Comminges, occupies an interface...
