(1999) :
The newly defined "Greenstone Unit" of the Aiguilles-Rouges massif (western Alps) - remnant of an early Paleozoic oceanic island-arc? Schweiz. Min. Petr. Mitt. 79/2, 263-276
Another metavolcanic sequence defined as the “Greenstone Unit” (Dobmeier et al., 1999) in the southwestern part of the Aiguilles Rouges Massif consists of an association of basalt to andesite and basalt to rhyolite lava flows of continental tholeiitic and calcalkaline affinity, respectively. These rocks have been interpreted as additional remnants of the above-mentioned Ordovician active continental margin.
