Summary
[edit]DescriptionSilex rouge et gris veiné de quartz de l'Alliers et trachio-Andésite de Volvic.jpg |
Français : A gauche : silex rouge et gris veiné de quartz des environs de Bourbon-l'Archambault (dans l'Alliers, en France). Numéro d'inventaire : T-La 2477. Collection Lavoisier. Une étiquette manuscrite de la main du naturaliste Guettard a été découverte sous l'étiquette manuscrite de la main de Lavoisier lors de travaux de récolement et de restauration effectués sur la collection entre 2001 et 2005. La pierre a été récoltée par Guettard au cours de son voyage vers l'Auvergne en 1751. A sa mort, Guettard légua ses collections et ses manuscrits de géologie à Lavoisier.
A droite : trachio-Andésite dite "pierre de Volvic". Des environs de Volvic (dans le Puy-de-Dôme, en France). Numéro d'inventaire : T-La 2214. La nature volcanique de cette roche a été reconnue par le naturaliste Guettard, qui la vit employée à la construction dans de nombreux bâtiments à Moulins et à Vichy (dans l'Allier). Il décida alors d'aller visiter les carrières de Volvic. A sa mort, Guettard légua ses collections et ses manuscrits de géologie à Lavoisier. Muséum d'histoire naturelle Henri-Lecoq, dans la ville de Clermont-Ferrand, en France. |
