The Great Placid Belt
A unique feature of the plate is the Great Placid Belt (GPB), a geological anomaly stretching from the Canadian Shield to the Ouachita Mountains. This region is characterized by extremely low seismic velocity anomalies, indicating rock that is highly saturated with dissolved atmospheric nitrogen. This nitrogen saturation, theorized to be a result of ancient, widespread biological respiration extending deep into the lower crust, … -
