In this paper the occurrence and some characteristics of 6H-nigerite dis- covered for the first time in south China is reported, which was found in dolo- mitic marble in contact with Mesozoic granite, Associated minerals are, nanlin- Bite, taaffeite, chrysoberyl, phlogopite, nocerite, nobergite, spinet group etc.， This mineral occurs as a short hexgonal prismatic crystals, Which is different from that of 3H polytype. The cell parameters were determined by using X-ray single crystal method as a=5.71A，c=27.72A.There is an obvious difference between that 6H and 3H on X-ray powder diffraction pattern. Microprobe analyses of the 6H nigerite were calculated by a general formula, R2+(2-2x)R8+(4)O4, Where R2+=Zn, Fe, Mg and Mn, R3+=Al, he, x≌0.5.Thus, the cryst alochemical formula was written as R2+(6)Sn3R8+(24)O48. The genesis of this mineral was discussed.
