Rifting and magmatism are fundamental geological processes that shape our planet's surface, but the nature of the relationship between these processes has been controversial. Here a numerical model that explicitly accounts for the effects of earlier episodes of extension has been applied to compare magmatism generated at different locations during continental rifting. The findings show that the volume of rift-related magmatism generated depends not only on the mantle temperature but also on the rift history.
