摘要
彭志忠石产于湖南安化白钨矿区,是一种富含镁、锡、铝的复杂氧化物。矿物为浅黄褐色、浅黄色,少量无色,晶体呈六方板状。晶体化学式为:(Mg,Zn,Fe,Al)_4(Sn,Fe)_2(Al,□)_(10)O_(22)(OH)_2,空间群P_3ml,a=5.692(5)A,c=13.78(2)A,V=386.7A^3,Z=1。D=4.22(3)g/cm^3,H≥8,一轴正晶,ω=1.802(2),ε=1.814(2)。
Pengzhizhongite-a new mineral named after Peng Zhizhong, a well kn-own mineralogist, was collected from a scheelite ore mine in the Anhua area,Hunan Province. It is an oxide rich in Sn, Al, Mg, etc. The mineral is lightyellowish-brown to light yellow, sometimes colorless wtth white streak. Hexa-gonal tabular. The crystallochemical formula is: (Mg, Zn, Fe, Al)_4 (Sn, Fe)_2(Al, □)_(10)O(22)(OH)_2·Space group P3m1; α=5.692(5), c=13.78(2) A, V=386.7A^3, Z=1, D=4.22g/cm^3, H≥8. Uniaxial(+), ω=1.802(2), ε=1.814(2).
