英文摘要Hezuolinite is a new mineral species occurring as an accessory mineral in the Saima alkaline complex in Liaoning Province, NE China. The mineral occurs in a green-aegirine nepheline syenite as non-metamict grains and is associated with microcline, nepheline, aegirine, biotite, eudialyte, rinkite and titanite. The anhedral crystals are several hundred micrometres in size. The mineral is black with dark-brown streak. It is translucent with a resinous luster. Cleavage or parting was not observed. It is brittle with a conchoidal fracture. The hardness is VHN100 683-964 kg mm(-2) (5.5-6 on Mohs' scale). The measured density is 4.28 g cm(-3), and the calculated value is 4.30 g cm(-3) from the empirical chemical formula. Optically, hezuolinite is biaxial negative, with n > 1.8 and 2V = 75 degrees. The dispersion is strong with r > v. The mineral shows a strong pleochroism, from pale brown to dark brown. The average of twenty-five analyses leads to the empirical formula (Sr2.15Ce0.55 La-0.49 Ca0.49Na0.12Nd0.09 Pr0.03Th0.03Sm0.01 Eu-0.01)(Sigma 3.98) (Zr-0.82 Fe2+ 0.14Hf0.02Mn0.01)(Sigma 1.00) (Ti-1.38 Fe3+ (0.36) Fe2+ (0.14) Al-0.04 Nb-0.02)(Sigma 1.94)Ti2O8 (Si2.01O7)(2), on the basis of O = 22. The simplified formula is (Sr,REE)(4)Zr(Ti,Fe3+, Fe2+)(2)Ti2O8(Si2O7)(2), ideally Sr2REE2Zr(Fe2+)Ti3O8(Si2O7)(2).
