摘要
1981年,在地质论评第27卷第5期刊登一篇题为“羟硅铍钇铈矿——一个富含铈、铍的硅酸盐新矿物”一文。当时,这篇文章的英文稿寄国际新矿物和矿物命名委员会审查。该新矿物于1982年一月经国际新矿物和矿物命名委会审查通过。现作者根据该会的意见和建议,将其羟硅铿钇铈矿(Yttroce-berysite)的矿物名称改为按产地命名,叫兴安石(Hingganite)。此外,对该新矿物的比重,光性方位,红外吸收光谱分析曲线,矿物的晶面符号、化学式和X光分析参数等资料又作了重新校正和微小的改动。
The data of the new mineral,Hingganite,was published in Geological Review Vol.27,No.5 in 1981.In this paper,on the suggestion of the Committee of New Minerals and New Mineral Names of the International Mineralogical Association,the writers offer some new data as follows.1.With the name Hingganite replaced Yttroceberisite.2.Density(g/cm3):4.42(meas.),4.45(calc.).3.Optical orientation:b=Nm,CANg=+13.4.X-ray powder diffraction pattern shows it to be monoclinic cell with a=4.790,b=7.545,c=9.989A.B=91 Z=4.The strongest lines are:6.004(3)(011),4.790(5)(100),3.772(4)(020,111),3.577(4)(021),3.462(5)(102),3.148(10)(112),2.865(10)(121),2.569(6)(113,122),2.377(3)(200,014),1.985(5)(221),1.880(5)(213,222,040),1.681(5)(214).Rarely idiomorphic crystals with(110),(011)and(001).5.Wet chemical analyses of material gave(%):SiO_(2)25.20,Fe_(2)O_(3)1.63,FeO 0.89,Al_(2)O_(3)1.695,TiO_(2)0.103,CaO 0.959,MgO 0.086,PbO 0.377,BeO 10.406,Na_(2)O 0.39,K_(2)O 0.775,La_(2)O_(3)3.600,CeO_(2)13.600,Pr_(6)O111.780,Nd_(2)O_(3)6.840,Sm_(2)O_(3)2.600,Eu_(2)O_(3)0.050,Gd_(2)O_(3)3.450,Tb_(2)O_(3)0.610,Dy_(2)O_(3)3.710,Ho_(2)O_(3)0.560,Er_(2)O_(3)1.310,Tm_(2)O_(3)0.070,Yb_(2)O_(3)0.570,Lu_(2)O_(3)0.090,Y_(2)O_(3)15.734 H2O 2.944,total 100.029.Corresponding to(Y_(0.33) Ce_(0.19) Nd_(0.10) La_(0.05) Fe_(0.05) Dy_(0.05) Gu_(0.04) Ca_(0.04) K_(0.04) Sm_(0.04) Na_(0.03) Fe_(0.03)^(2+)Pr_(0.02) Er_(0.02) Tb_(0.01) Ho_(0.01) Yb_(0.01))_(1.08)(Be_(0.97) Al_(0.03))_(1.00))(Si_(0.98) Al_(0.05))i.03 O4.00[(OH_()0.7)7 O_(0.233)]1.00 on the basis of O=5,Or ideally(Y,Ce)BeSiO_(4)(OH).This is(Y.Ce)Be analogy of datolite.
