Séminaire de Satish Singh, professeur à l'IPGP Abstract: The plate tectonics theory is based on the concept of a rigid lithospheric plate floating over a weak, deformable and convecting asthenosphere, separated by a boundary termed as the lithosphere-asthenosphere boundary (LAB). Determining the depth and nature of the LAB is fundamental for understanding the formation and […]

Diffusion chronometry now allows to quantify the igneous processes that occur on human timescales, and relate magmatic processes with the monitoring […]
