摘要
利用x荧光光谱和电子探针研完了青岛及诸城深源脉岩及其橄榄岩包体的岩石学和矿物化学特征,利用矿物地质温压计估算了其成岩平衡温压条件,确定它们为上地幔不同层次的深熔产物,推测它们形成于中生代晚期的岩石圈拉张背景。
The petrological and mineral chemical characteristics of the deep vein and peridotite xenolith from Qingdao and Zhucheng have been studied with XRF and electronprobe analysis. Their equilibrium temperature and pressure have been estimated with minerals geothermometer and geobarometer. It has been discovered that it was the anatectic matter of different layers in the upper mantle, and it was formed in the spread tectonic background in the lithosphere at the late of the Mesozoic era.
