- Abstract:
- Despite its critical positioning at the end of the Andean cycle in Peru, the Miocene (6-5 Ma) Yungay volcanic province in the high Cordillera Blanca, Peru (9 degrees S) remains unstudied. Reconnaissance data suggest that the Yungay volcanics are similar in composition to adakites, an enigmatic class of Na-rich volcanic rocks characterised by strong depletions in Y and heavy rare earth elements. Similar depletions in Archean trondhjemites are used to support an origin through slab melting. We will test the idea that the Yungay rocks (and by implication other continental arc 'adakites'), result instead from partial melting of hot, mafic lower continental crust situated above the underlying slab. If true, then adakite geochemistry is non-unique with respect to tectonic process and the only common denominator is the requirement of a mafic protolith.
