| 摘 要： | 利用电子探针分析蓬莱新生代玄武岩中的单斜辉石巨晶及尖晶石二辉橄榄岩包体中的主要造岩矿物(单斜辉石、斜方辉石、橄榄石和尖晶石)的化学组成。利用单斜辉石地质温压计和二辉石地质温度计计算了尖晶石二辉橄榄岩包体的平衡温度和压力,计算表明它们来自于上地幔的不同深度,同时推测本区上地幔内存在化学组成的分带性。

| Abstract: | Using electronprobe,we analyses the chemical composition of the main minerals in the spinel lherzolite xcnolith and the megacrysts within the Cenozoic era basalts from Ponglai,Shandong Province With clinopyroxene geothermometer and geobarometer and clinopyroxene-orthopyroxene geothermometer,we calculating its equibrium temperature and pressure.The equilibrium temperature and pressure of these xenoliths are different indicates that it comes from different depths and infered that in this area ( Ponglai area) the upper matnle composed by different zones in mineral-chemistry. |
