Delamination of the lower crust or lithospheric mantle is thought to have played a role in the formation of magma chambers that produced the extensive rhyolitic and basaltic eruptions in the Basin and Range region tens of millions of years after the last orogeny. This process involves the detachment and sinking of dense material from the lower lithosphere or mantle, which can then melt and generate magma.
