O manto litosférico subcontinental (MLSC) do terreno Cuyania está representado em xenólitos peridotíticos e piroxeníticos anidros da fácies espinélio hospedados em basaltos alcalinos pleistocênicos do vulcão Agua Poca, Província Basáltica Andino-Cuyana, Argentina. Os xenólitos mantélicos do vulcão Agua Poca são depletados, mas é possível identificar a influência de processos metassomáticos através do enriquecimento em elementos incompatíveis devido à interação com fluidos aquosos em um ambiente de extra back-arc continental. A composição geoquímica das amostras estudadas mostra correlação negativa entre os principais óxidos vs. #Mg, e padrão empobrecido em elementos incompatíveis em relação ao Manto Primitivo (MP). Com base em cálculos de f...
