<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 The region of the middle-lower reach of the Yangtze River is an important mineralized belt of Fe, Cu, Au, S and other elements, with a series of sedimentary-hydrothermal diplogenetic mineral deposits (Xu and Zhu, 1978; Liu et al., 1984; Gu and Xu, 1986; Gu et al., 1993, 2000; Zhai et al., 1992). Some geologists thought that the Carboniferous massive sulfide exhalative sediment was the basis of the late diplogenetic mineralization (Gu and Xu, 1986; Gu et al., 1993, 2000); o… 相似文献

<正>卡尔斯伯格洋中脊(Carlsberg Ridge;CR)位于印度洋北部,南端与中印度洋中脊相连,北端延伸进入红海。CR洋脊半扩张速率为11-16mm/yr(Ramana,et al.1993),为慢速扩张洋脊,具有类似于北大西洋中脊的地形地貌特征(Raju,et al.2008)。作为印度洋中脊的重要组成部分,CR洋脊是最年轻和最复杂的洋脊之一,也是研究程度最低的洋脊之一(Murton,et al.2005;Nauret,et al.2006;Ray,et al.2013)。印度 相似文献
