文摘

The Qianlishan complex is an A2-type granite, formed at ~ 158–154 Ma induced by slab rollback. The A2 signature of the Qianlishan granite indicates mantle metasomatism during plate subduction. Fractionation of reduced granitic melts and melt–fluid interaction account for the formation of Shizhuyuan W–Sn deposit.
