| 摘 要： | 本文在原有湿法化学分析结果基础上对南岭石的矿物化学式做了重新计算,纠正了原化学式的错误,并对晶胞参数做了精确测定。经晶体结构测定,确认本矿物不仅是以(AsO3)阴离子团的氧原子密堆积作为结构框架外,其中还出现了Fe-As成键的新特征,属于一种新结构类型的新矿物。红外光谱及穆斯堡尔谱分析测试显示了本矿物波谱学方面的特征。对矿物新的化学组成除采用电子探针、能谱手段以外,还运用SIMS离子探针证实了锂的确实存在。

| Abstract: | On the basis of the former wet-chemical analysis data of the Nanlingite, the new chemical formula was obtained through re-calculating, and original mistake was corrected also. The cell dimensions was refined by four-cycle diffractometer, and the crystal structure was determinated in this study confirm that, it belong to a new model of the dense-packed oxygen atoms with Fe-As chemical bond. The feature in spectroscopy of the mineral has manifested from the infrared and Mossbauer spectrum analysis. The composition of the mineral in this paper was adopted by EMP and energy spectra method. In order to verify the existence of Li element, the SIMS probe was applied emphatically, being about good results. With the exception of mentioned above, the paper discussed also the genesis of Nanlingite. |
