摘要
通过对某些磷灰石的化学成分、粉晶x射线衍射及红外光谱特点的综合研究后发现,不同成因磷灰石具有不同的晶体化学特征。其中,岩浆型磷灰石含OH^-较多而CO_2较少,热液型的含cl^-高且a_9、c_9值较大,而沉积型的则以高CO_2与co/a_0值为特征。由各种样品的IR谱对比,作者认为,2000cm^(-1)附近的吸收峰是磷灰石的固有吸收,可能是由与附加阴高于OH^-、F^-有关的晶格振动所引起。
Abstract The characteristics of some different genetic apatites are studied with chemical, X-
ray diffractional,and IR spectral analysis. The results show that the apatite of igneous gene-
sis has higher OH- and lower CO2 contents; the hydrothermal genetic one has higher Cl-
content and higher values for a0 and C0 ;and that of sedimentary genesis contains much more
CO2 and has high value for C0/a0. The absorption wedges near 2000cm-1 on the IR spectro-
gram might be attributed to the vibrations of OH- and F- in the structure.
