| 摘 要： | 大容山-十万大山花岗岩带由花岗岩、花岗斑岩和少量混合花岗岩、酸性火山岩组成,它们共同构成一个原地半原地→中深成侵入→浅成侵入→喷出相的完整花岗岩类成因系列。这些岩石在矿物组成、化学成分、微量和稀土元素以及同位素组成上十分相似,都来源于上部地壳,属陆壳转生型花岗岩,其源岩是由角闪岩相到麻粒岩相的变质沉积岩。

| Abstract: | Granitoids in the regions of Darongshan and Shiwandashan are composed mostly of granites, granite-pophyry and some migmatitie granites,and acidic volcanic rocks as well. The similarity of these rocks in mineralogical and chemical compositions and in Sr-Nd-O isotopes suggests that they were likely derived from the same sources and assemble a rock series of granitoids ineluding plutonic rocks, hypabyssal rocks and eruptive ones.The source rocks of them are metasedimentary rocks of amphibolite-granulite faces. |
