Abstract: The Tarim Large Igneous Province (Tarim LIP) agrees well with the mantleplume model in terms of its tempo-spatial distribution of Permian igneous rocks. Thedomal uplift of the crust before eruption, widespread dike swarms and occurrenceof picrat...[继续阅读]

    The intrusive rocks in the Tarim LIP, mostly exposed at Xiaohaizi and Wajilitagof the Bachu area (Fig. 3.1), include ultramafic–mafic layered intrusions, syeniticrock bodies (and perhaps some A-type granitic plutons), radiating mafic dikeswarms, and ultra...[继续阅读]

    Mafic–ultramafic intrusions, as a distinct feature of the Emeishan LIP in SWChina, such as the Panzhihua, Hongge and Xinjie intrusions, have been widelysurveyed and studied (Zhong et al., 2002; Zhou et al., 2005; Wang et al., 2008;Pang et al., 2008). They...[继续阅读]

    Olivine of the olivine pyroxenite rocks has higher Fo values than those of otherrocks (Supplementary Table II), being supposed that the former may crystallizemuch earlier than those in the latter. Nevertheless, the Fo values of all olivines(Fo=67–76 mole%...[继续阅读]

    The Siberian Traps are regarded as the largest LIP on land, i.e. up to 3.9×106km2 (Reichow et al., 2002; Renne, 2002). There are 11 basalt suites which canbe grouped into 2 sequences. The lower sequence consists of sub-alkalic basalts,tholeiites and local...[继续阅读]

    The Permian basalts in the Tarim Basin are widely distributed in the westernand central parts of the Basin (Fig. 2.1). Yang et al. (2007a) reported that thethickness of basalt lavas ranges from tens to hundreds of meters, and the spatialdistribution area ...[继续阅读]

    The quartz syenitic porphyritic dike occurred in Shuigongtuan of Bachu County,Tarim Basin. The concordia age of (277±4) Ma was obtained from the Xiaohaizisyenitic body by the SHRIMP zircon U&8210;Pb age dating system (Yang et al., 2006),indicating that th...[继续阅读]
