Recent detrital zircon studies on the Neoproterozoic Jacobsville Sandstone in the upper peninsula of Michigan have revealed that the deposition of the Jacobsville postdates volcanism associated with the Midcontinent Rift (MCR). Detrital-zircon ages show that the Jacobsville sandstone has a maximum depositional age of 959 ± 19 Ma and may be at least 200 m.y. younger (Malone et al., Geosphere, 2016).
