Revisiting lithospheric dripping: Modern crustal xenoliths from the Colombian arc suggest heterogeneous viscosity and cyclic instability development

Lithospheric dripping is often invoked to remove dense material from arcs. However, the thickness, timing, and mechanical properties that lead to detachment of lower arc crust remains poorly constrained. The Mercaderes xenolith suite erupted <280 kyr in the Northern Volcanic Zone...
