    A whole-rock Sm–Nd isochron age of (306±7) Ma was reported for theWajilitag intrusion (Lu et al., 2000). But Zhang et al. (2008) considered that theemplacement age of the intrusion might be ca. 275 Ma based on the zircon U–Pbdating of the syenite in the B...[继续阅读]

    Bimodal dikes may provide the key to understanding the rifting environment ofthe Tarim Block. Bimodal volcanic suites form in various tectonic settings, suchintracontinental rifting (Shao et al., 2001; Li X.-H. et al., 2002; Lindline et al., 2004;Vorontso...[继续阅读]

    A great many of the metal mineralizations can be associated with plumemagmatism, such as copper ore deposits, Cu—Ni sulfide deposits and V—Timagnetite ore deposits. These ore deposits resulting from mantle plume areusually larger than those formed in a no...[继续阅读]

    Besides the Tarim LIP, there are two other significant Permian LIPs currentlyreported in Central Asia, the Emeishan LIP and the Siberian Traps (Fig. 4.8). TheEmeishan LIP is now situated in southwestern China, with a distance of about2300 km from the Tari...[继续阅读]

    ●PicriteAll of the picrite samples recovered from the boreholes in NTU are altered; however,typical petrographical features, such as the porphyritic texture and pseudomorphsafter olivine phenocrysts, are well preserved. Petrographically, recognized groups...[继续阅读]

    The above considerations indicate that the degree of partial melting plays animportant role in the Cu–Ni–PGE mineralization in the Tarim LIP. Due to verylow degrees of partial melting, the Tarim CFBs are extremely PGE-depleted,which may account for the ab...[继续阅读]

    The Permian Xiaohaizi syenite body and dikes are well-developed in theXiaohaizi and Wajilitag areas in Bachu County in the northwestern Tarim Basin.Near the Xiaohaizi water reservoir in the Bachu area, a syenite body with surfaceexposure of several square...[继续阅读]

    The Wajilitag area is located in the southeastern part from Bachu County at adistance of 40 km. A basic—ultrabasic complex pluton covers an area of about10 km2 and is made up of a layered rock body, cryptoexplosive breccia pipesand a late-stage diabase di...[继续阅读]
