摘要
哈秀石英闪长岩体分布于哈秀-隆宝断裂带及立新-歇武断裂带之间,Si O2含量介于59.77—71.02×10-2之间,属中酸性岩。锆石U-Pb年龄分别为北部:219.2±1.6Ma,南部:214.2±2.2Ma。岩石地球化学特征显示,哈秀黑云母石英闪长岩属钙碱性系列,具有明显的壳源岩浆特征,岩体构造环境为火山岛弧区。
In this paper, the authors show that the quartz diorite diorite is distributed in the fault zone between the Xiu Long Bao fault zone and the new fault zone, the Si O2 content is between 59.77 and 71.02 × 10-2, which belongs to the intermediate acid rock. Zircon U-Pb ages were in the North： 219.2 ＋ 1.6Ma, South： ＋ 214.2 ＋ 2.2Ma. According to the rock geochemical characteristics of haxiu biotite quartz diorite calc alkaline series, with obvious characteristics of crust derived magma rock, tectonic environment for volcano arc zone.
