.... The Quantico formation consists of mica schist and minor amounts of quartzite that are sedimentary in origin. The sediment was deposited in a postorogenic successor basin and was subsequently deformed during the Alleghanian orogeny ( Carter et al. , 2020 ). The granodiorite Ellisville Pluton and associated...

... are the Columbia and Ellisville plutons, which yield U-Pb zircon ages of 457 and 444 Ma, respectively ( Wilson, 2001 ; Hughes, et al., 2013 ). Successor basin deposits of the Arvonia and Quantico Formations unconformably overlie both the volcanic and plutonic rocks (Fig. 4A). Based on their fossil assemblages...

.... (2013) have now dated the Ellisville pluton as young as ca. 437 Ma and interpreted the Quantico Formation similarly as a Silurian successor basin. However, the Horton et al. (2010) date suggests that the Quantico is not a successor basin, as its age cannot be older than the plutonic rock on which...
