Mineralogical Geochemistry of Ultramafic Hypoxenoliths in Alkali-Rich Porphyry
Ultramafic hypoxenoliths found in the alkali-rich porphyry in the Liuhe Village, Heqing, Yunnan, China, are of great significance in understanding the origin and evolution of the porphyry. This paper discusses the mineralogical features of the hypoxenoliths. It shows that the xenoliths are characterized by the upper mantle rocks modified to certain extent by the enriched mantle fluid metasomatism in the mantle environment, with the enriched mantle property of low-degree partial melting. This constitutes the important mineralogical evidence for the geochemical background of petrogenesis and mineralization of alkali-rich porphyry.
