<span style="background-color: rgb(255, 255, 255); text-transform: none;">Gravitational foundering (lithospheric dripping or delamination) is considered an important mechanism for removing dense, mafic portions of volcanic arc crust. Does a similar process
also operate beneath back-arc orogens and thereby contribute to mountain building? Some geologic and geophysical data provide evidence for this "drip tectonics" hypothesis, but it remains poorly understood. In this talk, I will present results from geologic
mapping in the Andean Puna Plateau, along with geodynamic and thermodynamic simulations. These results suggest that dripping/delamination may be intrinsically linked to plate tectonics through crustal thickening and fluid migration, and they highlight a need
for further research to understand the feedbacks between fluid infiltration, metamorphism, and deformation</span></div>
