Geochemical Connection between The
 Granitic Plutons and the Rhyolitic
 Volcanics: A Case of the Cretaceous
 Granitic Magmatism in the Central
 Sulu Orogen, Eastern China

There was a early Cretaceous felsic LIPs developed in the central Sulu orogen. It contains multi-stage granitic pluton and andesitic-dacitic-rhyolitic volcanism. The crystal-poor rhyolitic ignimbrite in Lingshan island has been proved not to be derived from the intermediate igneous rock. This research focues on constructing the geochemical connection between the eruptive rhyolite and the plutonic granite. The granitic pluton is a suit of I-A type association represented by alkali granite (A-type) and syengranite (I-type). The Zircon U-Pb dating results give the ages of the rhyolite, the A-type granite and the I-type granite are 121.6±1.3Ma, 120.7 ± 1.8Ma and 116.8±1.1Ma respectively. The I-type and the rhyolites show similar geochemical characteristics with extremely high SiO 2 (75~79%), low MgO content(0.1~0.2%) and strong Eu anomaly (0.3~0.4), but the I-type ones have lower REEs contents. These suggest the rhyolite is not derived from the I-type granite although the rhyolites are ploted in I&S&M area in the X-1000Ga/Al diagrams. The rhyolite is likely formed by removing mineral assemblages of (0.77Fsp + 0.125Plag + 0.05Bt + 0.033Am + 0.006Ap
