摘要: Miyashiro (1973) famously initiated a debate on the tectonic setting of ophiolite complexes by proposing that 'the Troodos ophiolitic complex was probably formed in an island arc'. This paper evaluates and updates Miyashiro's work by:(a) using the Mehegan–Robinson set of 137 fresh volcanic glass analyses to sidestep the controversy over the effect of alteration on major element classification diagrams;(b) using the volcanic glass database for Troodos analogues such as back-arc basins, slab edges, forearcs and subduction initiation …
