补充资料:英云闪长岩
一种显晶质中酸性侵入岩。相当的喷出岩是英安岩。英文名tonalite来源于意大利蒂罗尔山(Tonale)。主要由斜长石(中长石、更长石,约占2/3)和石英、黑云母组成,斜长石常具环带构造。较富铁镁矿物,除黑云母外,有时含角闪石、辉石。此外,可含碱性长石(一般是正长石),并往往呈填隙物产出,但其量不足长石总量1/10。常见副矿物是磷灰石、榍石、磁铁矿。因此,英云闪长岩在矿物组成上大体与石英闪长岩相仿,是介于闪长岩和花岗闪长岩之间的中间岩石;虽以较富石英和云母的特点区别于石英闪长岩,但它们之间不易测定确切的矿物定量界限。英云闪长岩主要呈单个小岩体或呈辉长岩、苏长岩等有关岩石的边缘相产出,较少是单独的大岩体。
