Abstract

The contribution of Decarlis et al. (2018) focuses on the breakup of continents at magma-poor rifted margins, a topic which, as claimed by the authors, “… is a complex, yet little understood ….. accounting for intricate interactions between tectonic and magmatic processes”. The authors use field observations of a classical Ligurian ophiolites exposure – the Bracco-Levanto - to compare it with the setting of the East Antartica margin analyzed by seismic survey and interpretations (Geoscience Australia Survey 228). The authors state that the overall aim is to combine detailed structural mapping and petrological data from the fossil exhumed example (Bracco-Levanto) with architectural features observed in seismic sections from present day OCTs.
