Ferrifayalite is a Fe~(3+)-rich silicate mineral. It occurs in the Anshan type-like magnetite deposit of Liaoning Province. Ferrifayalites distribute unevenly and aggregate commonly as bands, with a percentage usually lower than that of magnetites, occasionally reaching to 10%. Crystals of ferrifayalite mainly xenomorphic granular, 0.25—0.7mm. to individually 1mm in diameter. Color blackish, luster submetallic with blackish brown streak. Cleavages of (100) distinct, (010) indistinct. Non magnetic but mediumly electro magnetic. Hardness 5.5—6.5 S. G. 3.967.Opaque. Under reflected polarizing microscope, grey in color, anisotropic and with distinct bireflexicon (reflection-pleochroism). Indices of refraction were calculated from reflectivities : ∥ cleavage, N_(546)=2.03±0.04, N_(589)=2.01±0.04;⊥cleavage, N_(546)=2.04±0.04, N_(589)=2.03±0.04. Biref. △_(546)=0.01; △_(589)=0.02.Chemical composition of ferrifayalite rather simple and stable Pe_2O_3 content high, occasionally reaching to 45.1%. Th crystallochemical formula is Fe~(2+)Fe~(3+)(SiO_4)_2.Monoclinic in system. Space group C_(2h)~5-P2_1/b.a=4.808, b=10.171, c=5.824, α=90°.X-ray powder strong lines: 3.488(10), 2.774(9), 2.521(10), 2.405(7), 2.246(7), 1.745(8) etc., some with scattering phenomena.In the curve of D. T. A., there is one heatemitting peak at 700℃.In the infrared absorption spectrograph there are SiO_4 deformation vibration at 840—1120 frequency region.In single crystal structure analysis uses were made with equi-inclination weissenberg multiple film method according to olivine orientation. We had collected seven sets of diffraction photographs of 0kl-2kl, hk0-kh2, hOl, totally 246 independent diffraction spots. The photographs show V_h-D_(2h)-mmm laue symmetry, and on account of the crystal possessing neither gliding plane n nor symmetrical plane m of the spacegroup of olivine D_(2h)~(16)-Pbnm, it is thus determined the sole space group to be C_(2h)~5-P2_1/b. The parameters of the coordinates of every kind atom are determined after crystallochemistry principle and Patterson projection pattern. R_(oxt)=0.23, R_(hko)=0.21.The crystal structure analysis shows that ferrifayalite is an independent mineral with ordered vacant lattice position olivine type structure. It shares some features in common with that of olivine structure type, including a similar orientation of the tetrahedron, but it is different from olivine structure type in consisting of the edgesharing octahedral linear chains instead of the zigzag chains. Fe~(2+) situate at the center of symmetry of olivine, but it is vacant in this mineral at (0, 0, 1/2) and (1/2, 1/2, 1/2) symmetrical centers. Thus the structure becomes an ordered vacant lat- tice position structure.The cleavages, hardness optical properties etc. can all be properly explained with structure.After comparing the chemical composition, physical properties and size of unit cell of this mineral with that of MnO_2-bearing ferrifayalite informed by I. W. Ginsburg, the authors of present paper believe that these wo minerals possibly belong to the same kind of mineral, but the structure as they thought is quite different to ours.

W.金兹堡等人所报道的含MnO_2Ferrifayalite比较,本文作者认为二者可能属于同类矿物,但他们认为该矿物是由锰铁橄榄石+Fe_2O3、+SiO_2三个物相所组成的非独立矿物,他们推测该矿物的结构与本文显然是不相同的。

长期以来,差热分析主要是作为矿物鉴定的一种手段。但是,随着热分析仪器的日趋完善及热分析与其他测试手段的联用,逐渐显示出差热分析方法在矿物研究中应用的广阔前景。最近,在以下几方面取得了初步结果:1.研究了同种而不同成因矿物之间的微细变化,进而推论矿物形成的物理化学条件;2.矿物加热变化机理的解释和说明;3.分解反应的动力学分析;4.转换热和分解热的测定。 本文从钙-镁-铁-锰系列碳酸盐矿物差热曲线特征的研究着手,讨论了不同成因菱铁矿、镁菱铁矿差热曲线的特征。
