The transition to deeper level partial melting apparently occurred during the Lochkovian Stage of the Early Devonian based on the emplacement age of 415.5 [+ or -] 2.1 Ma for the Wellington Lake Granite, the youngest 'A-type' pluton, and the emplacement age of 413.3 [+ or -] 2.1 Ma, for the John Lee Brook Granite, the oldest 'S-type' pluton in the backarc region; the former was likely generated at least in part by partial melting of Neoproterozoic volcanic and plutonic rocks underlying the Mascarene belt, and the latter at least in part by granulite-facies dehydration melting of pelitic rocks of the St.
