Descripción y resultados preliminares del plutón compuesto de San Xiao, Complejo de Cabo Ortegal (noroeste del Macizo Ibérico)

The San Xiao composite pluton is a small body intruded in a metasedimentary formation of the Cabo Ortegal Complex upper units, the Cariño Gneisses. In spite of its size, it exhibits spectacular evidence of magma mingling processes. Based on the compositional features of the rocks and their relations...
