摘要
硼磷镁石(Lueneburgite,)系一种稀少的含水含磷硼酸盐矿物。该矿物1870年发现于德国汉诺威的吕内堡。现已知国外产地有:美国新墨西哥二叠纪含盐盆地,苏联里海的卡拉—博加兹—戈尔海湾及喀尔巴阡的斯捷布尼克等地区。此外,在秘鲁鸟粪石沉积层中也有发现。
Lueaeburgite(Mg-I borate)was discovered in 1968 by the author,in spite of its rarity as from a mirabilite deposit in Shansi,China.Different methods of identifications have been performed on the mineral for its mineralogical aspects with such as microscopic and SEM determinations,and spectra!,microscopic laser spectral,chemical,differential thermal and infrared spectral analyses.It is demonstrated that the Mg-P borate,formula Mg_(3)B_(2)O(OH)_(4)(PO_(4))_(2)·6H_(2)O,occurs as spherical aggregate and exhibits a diversity in morphology,with cell parameters a=9,710A,b=7,553A and c=9,922A,andβ=97°06′.The strongest lines in the powder diffraction pattern are 5,00(10),2,97(10),4,87(9),2,83(9),3,25(8),3,03(8)andl,943(7),and the main infrared absorption bands,3399,3232,1663,1122,1074 and 10^(19)cm^(-1).
