In the Hainan Island, the Middle Triassic syenite-granite suite, with outcropped total area of 516 km², was distributed along the Lingshui-Longgun deep fault and on the southeast side of the Baisha deep fault. It is composed of quartz monzonite, quartz syenite and syenogranite. The suite is classified in A-type granitoids, in which the granites were probably generated from quartz syenitic melt through crystallization differentiations of minerals, such as feldspar, hornblende, apatite, ilmenite, sphene, etc. And the quartz syenitic melt may be derived in the deep crust mainly by differentiation of alkali basaltoid magma which was originated from the EM di-font-family: 宋体">Ⅱ-type enriched mantle. The suite is considered formed in a post-orogenic extensional tectonic setting.
