摘要
选取江南造山带西段湘西怀化地区~788 Ma辉绿岩中的钛铁矿为研究对象,采用电子探针对其化学成分进行了精确测定。绿岩中钛铁矿属典型的钛铁矿,具有相对较高的TiO_(2)、MnO、V_(2)O_(3)含量,中等的FeO和Fe_(2)O_(3)含量,以及很低的MgO含量,具有形成于幔源岩浆活动钛铁矿的特征。
Chemical composition of ilmenite from the~788 Ma diabase in Huaihua area of western Hunan Province in the western part of Jiangnan Orogenic belt was determined by electron probe.The ilmenite in greenstone is a typical ilmenite with relatively high contents of TiO_(2),MnO and V_(2)O_(3),medium contents of FeO and Fe_(2)O_(3),and very low contents of MgO.It has the characteristics of ilmenite formed in mantle-derived magmatic activity.
