摘要
Some characters of the petrology and petrochemistry of the volcanic rocks of the Gangdise-Nyainquentanglha magmatic arc were involved in some of our discussions. In this paper we discuss mainly the geochemistry of REE and trace elements. The samples are representatives of the Jurassic-Cretaceous andesite (N-3) and basalt (N-1) belonging to ealc-alkali series in Nyainqentanglha area, Cretaceous andesite (5-92),
