查询词典 trace

The mineral chemistry, trace elements and Sr-Nd isotopic geochemistry of different types of deep-seated inclusions indicate that Group Ⅰinclusions in western Shaudong could be the relicts of high degree of partial melting of the mantle-derived peridotites and then subjected to mantle metasomatism; the dunite and harzburgite in Group Ⅱ inclusions could be resulted from the metasomatism of silica-rich melts in the upper mantle; the olivine-pyroxenite and pyroxenite in Group Ⅱ and Group Ⅲ inclusions could be magmatic cumulates derived from magma underplating in the upper mantle.
