宁远─道县辉长岩包体的地球化学特征

Geochemistry of Gabbro Inclusion in Ningyuan-Daoxian Counties

宁远─道县地区中生代玄武岩中辉长岩包体的岩石化学─地球化学特征表明，辉长岩包体为钙碱性玄武岩系列，形成于活动大陆边缘火山孤环境。辉长岩的形成、侵位，与菲律宾板块自中生代以来向中国大陆俯冲作用有关。

In Ningyan-Daoxian counties there exist gabbro inclusions in basalts of Mesozoic Era. Its petrochemical and geochemical features show that the inclusion belongs to the series of calc-alkaline basalt in nature and forms in the environment of volcanic arc on the active continent margin. Formation and emplacement of gabbro inclusion are related to the subduction of philippines’plate underthrusting downwards into China continent since Mesozoic Era.
