AGU Session announcement T029: Magmatism and Extension During Continental Rifting
From: David Ferguson <davef@xxxxxxxxxxxxxxxxx>
****************************************************************************************
Rifting is commonly associated with magmatism, which varies with space, time and geodynamic setting. In East Africa, where the geological record preserves a long history of rift development, the locus of strain has shifted over time from a broad zone of mechanical extension to a narrower zone of magmatism, reminiscent of a mid ocean ridge. In contrast, in the Basin and Range, extension and volcanism have been maintained over a relatively broad area for 15My and the links between magmatism and extension are less clear. We invite contributions from geoscientific studies that constrain the structure and dynamics of all regions of extension with a view to understanding better the manner in which strain and magmatism develop during rifting.
