<正>目前,对于斑岩铜矿的研究主要集中于探讨温度区间为200800℃范围内矿床的成因问题,例如岩体形成时代及顺序、矿化和热液蚀变时代以及热液活动时限等(Barra et al.,2002;Masterman et al.,2004;Deckart et al.,2005;Pollard et al.,2005;Campbell et al.,2006;Mao et al.,2006;Baumgartner et al.,2009;Redmond and Einaudi,2010;Sillitoe and Mortensen,2010;Vry et al.,2010;Shen et al.,2012;Zhu et al.,2012)。虽然这些问题很重要,但是仍然不足以全面的认识和 相似文献

1 Introduction Voluminous literature has resulted from study of the geology and tectonic evironments of post-orogenic granitoids in eastern Tianshan (He et al., 1995; Han et al., 1997; Gu et al., 1999, 2001; Li et al., 2003; Chen et al., 2004). Previous contributions (Hu et al., 1997; Li et al., 2003) indicate that major events of continental collision in northern Xinjiang occurred around 300 Ma. Then, the tectonics converted from compression to extension, resulting in the uplifting of th… 相似文献

Several thrust faults have been mapped in theYanshan belt ,as the thrust structure was first iden-tified by Wong (1928) (Ji et al .,2005 ; Wang et al .,2005a ;Davis et al .,2001 ,1998 ; Yang et al .,2001 ;Zheng et al ., 2000 ; Chen, 1998 ; Zhang et al .,1986 ; He ,1957 ;Chern and Hsiung,1935) .Becausethe Archean basement was widely involved in thethrust systemof the Yanshan belt ,domestic popularrecognition emphasized the thick-skinned characteris-tics and li mited horizontal displacement… 相似文献

<正>越来越多的研究结果表明,Re在不同硫化物间存在一定的分配规律。例如:辉钼矿的Re含量往往比共生的黄铁矿(Li et al.,2011)或黄铜矿(Zhu and Sun,2013)高3~5个数量级;黄铁矿的Re含量普遍比闪锌矿(Morelli et al.,2004)和方铅矿(Stein et al.,2000)高3~30倍;铅锌矿床中闪锌矿的Re含量又明显高于方铅矿(Liu et al.,2015)。这些很可能与Re在硫化物中分配系数的差异,即各硫化物载Re能力的 相似文献

<正>The podiform chromitites in the Luobusa ophiolite,Southern Tibet,have received much attention because of the presence of ultrahigh-pressure minerals,such as microdiamonds(Bai et al.,1993;Yang et al.,2007;Xu et al.,2009),coesite(Yang et al.,2007)and highly reduced metal phases(Bai et al.,2000;Robinson et al.,2004).The 相似文献

1 Introduction According to recent researches, the North China Craton consists of three parts: the eastern block, western block and central zone (Zhao, 2001; Wilde et al., 2002). Paleoarchean continental blocks and zircon residuals have only been found in a few regions, such as Anshan, East Liaoning (Liu et al., 1992; Song et al., 1996; Wan et al., 2002, 2005), Caozhuang, East Hebei (Liu et al., 1992) and Xinyang, West Henan (Zheng et al., 2004), which are mainly distributed in the east… 相似文献
