Thermal stabilization of the Zimbabwe Craton deduced from high-precision Rb-Sr chronology, Great Dyke

Nebel, Oliver; Mezger, Klaus

Description

Dating low temperature events such as magmatic cooling or (hydro-)thermal surges in Archean and Proterozoic terranes is crucial in defining cratonal thermal stabilization after episodic continental growth during the Archean and Early Proterozoic. Rubidium-Sr chronology is potentially a powerful tool in this regard because of its low closure temperature, i.e., ∼<400 °C in most minerals, but has until now been hampered by its relatively low precision compared to high-temperature chronometers....[Show more]
