月岩的穆斯堡尔谱学研究

The results of Moessbauer study of Apollo-17 Mare basalt are reported in this paper.It has been revealed that Fe in iron.bearing minerals in the basalt is almost present in the form of Fe^3 , with Fe^3 less than 3% of total iron. The site occupancy of Fe^3 ions at M1 and M2 is approximately 0.3 and the corresponding equilibrium constant K (T) is about 0.06, thus indicating that the mare basalt is formed through crystallization under high-temperature reducing and rather slow cooling conditions.     

橄榄石中铁有序度的穆斯鲍尔谱学研究

橄榄石是与铬铁矿成因有关的造岩矿物之一,为探讨铬铁矿的成因,有必要对橄榄石中Fe~(2 )的有序、无序分布进行研究。本文用穆斯鲍尔谱学研究了与我国陕西松沟铬铁矿共生的橄榄石中Fe~(2 )在八面体配位位置上的分布,为该矿物形成条件的探讨提供一定的信息。实验是在电磁推动的等加速度穆斯鲍尔谱仪上进行的。实验装置作透射几何安排。从样品透射的γ射线,由一个端窗形的流气式正比计数器接收后,送入多道分析器以多路定标方
