<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

华北克拉通北邻中亚造山带,南接秦岭-大别-苏鲁造山带.它通常被认为是约18亿年固结形成的陆块.其基底的形成与演化,一直受到广泛关注(Zhao et al.,1998,2000,2005;Zhai et al.,2000,2005;Wilde et al.,2002,2005;Guo et al.,2005;Kroner et al.,2005,2006;Lu et al.,2008).大多数研究者都注重于华北克拉通内部、北部和东西陆块结合带(中间带),较少关注东南缘基底的形成与演化研究. 相似文献

1 Introduction The tectono-thermal evolution of the North China Craton (NCC) in Late Archean to Paleoproterozoic times has long been attractive to many researchers (Wan et al., 2000; Zhao et al., 2000, 2002; Guo et al., 2001; Liu et al., 2002; Zhai and Liu 2003; Zhai, 2004; Yu et al., 2004; Kr?ner et al., 2005; Wilde et al., 2005). Zhao et al. (2000, 2002) proposed a tectono-thermo framework for the evolution of the NCCbased on detailed petrological and geochronological data, and they … 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

<正>重金属污染对于多数微生物生长有毒害作用。但在污染环境中,往往也存在一些对重金属胁迫具高耐受性的微生物菌种,他们可用于生物修复、工业废水处理等实际应用(Bosecker,1997;Anand et al.,2006)。过去十年中,对微生物吸附重金属的研究取得了很大进展。大量研究表明,一些微生物如细菌、真菌和藻类等对重金属都有很强的吸附能力,并且对生物吸附的机理也有了一定了解(Barros et al.,2007)。近年 相似文献

正1 Introduction Vegetation indices (VIs) derived from satellite observations are an essential source of information for operational monitoring of the Earth's vegetation (Qu et al.,2018;Yan et al.,2008).However,soil background dramatically affects the performances ofⅥs (Baret and Guyot,1991;Gilabert et al.,2002;Huete,1988;Qi et al.,1994).So soil-adjustedⅥs (Baret and Guyot,1991;Gilabert et al.,2002;Huete,1988;Qi et al.,1994) are 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

<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
