| 中文摘要:华仁民先生和王登红博士对笔者发表在《矿床地质》上的“花岗岩与金铜和钨锡成矿的关系”一文提出了质疑。笔者欢迎他们的质疑，并再次强调，花岗岩按照Sr-Yb的分类不是成因分类。分类是有客观标准的，其含义可以有不同的解释，笔者认为该分类与花岗岩形成的压力有关。花岗岩与成矿有关，不是成因有关，而是时空有关。因此，“含矿岩体”和“成矿母岩”的说法是不对的。成矿如果与成岩有关，二者大体是同时的，成矿早于或晚于成岩都是合理的。与金铜有关的是埃达克型和喜马拉雅型花岗岩，与钨锡成矿有关的主要是南岭型花岗岩：前者与地壳加厚有关，后者与地壳减薄有关。因此，金铜和钨锡一般不共生。为了深入讨论问题，应当建立在详细和精确资料的基础上。 |

| Abstract:We welcome the comments by Hua (2010) and Wang (2010). It is noted that the Sr-Yb classification for granitic rocks that we proposed is not the one based on the origin of granitic rocks, instead it is an indicator for the pressure under which the granitic rocks were formed. Therefore, Cu-Au mineralization is associated with adakitic and Himalayan-type granitic rocks formed from thickened lower crust (high-pressure), whereas W-Sn mineralization is related to Nanling-type granitic rocks formed from thinned crust (lower-pressure). The Cu-Au mineralization and the W-Sn mineralization are thus not genetically related to each other； they may be overlapped within the same granitic plutons at different times. We also propose that the granitic plutons that host either Cu-Au or W-Sn mineralization might have nothing to do with the mineralization in genesis, and they are only spatially related or sometimes temporally related to each other. However, any further detailed discussion on the relationship between granitic plutons and Cu-Au and W-Sn mineralization should be based on accurate ages and whole-rock geochemical data. |
