Advances in our understanding of magma-poor and magma-rich rifting processes
Advances in our understanding of magma-poor and magma-rich rifting processes
Session ID#: 124838
Session Description:
Rifting is one of the key tectonic processes that shape the Earth’s surface. The full rupture of continents involves thinning and stretching of the entire lithosphere with interactions from sub-lithospheric mantle. In many cases, magma plays an important role in accommodating extension (magma-rich rifting), yet in other settings the role of magma appears limited (magma-poor rifting). In addition, some rifts are characterized by strain accommodation within relatively narrow zones, whereas other rifts accommodate strain over wider regions. In this session, we welcome contributions from the observational, modeling, and experimental communities that address advances in our understanding of magma-poor and magma-rich rifting processes for both narrow and wide rifts that span the earliest phases of rift initiation to the fully extended stage of rifted margins. In particular, we encourage cross-disciplinary submissions that integrate a wide range of data sets and techniques to address the first-order processes controlling continental rifting.
