摘　　要：南华砷铊矿床中－种铁的硫砷化合物矿物新发现张宝贵，王三学，张忠，张兴茂，王明再（中国科学院地球化学研究所．贵阳５５０００２）关键词砷铊矿床，铁的硫砷化物，云南本文报道的铁的硫砷化物矿物产在云南南华砷铀矿床中，是矿床主要含纯矿物之一。铅灰白色，不透明，...A new mineral of ferric sulfarsenide occurs in the Nanhua As-T1 ore deposit in Yunnan province. The major coexisting minerals are quartz,dolomite,realgar orpiment, galena, sphalerite, hutchinsonite, etc. Reflectivity (R % ) of the sample at various wavelength ismeasured: 41. 90(578), 37. 45(582), 37. 97(585), 39. 54(580), 40. 32(580), 40. 01 (580), 41. 00(580), 41. 43 (577 ), 40. 98 (579), 39. 23 (581). Electron microprobe analyses of ten samplesgave (%):S 40. 38(44. 02￣47. 33),As 15. 16(13. 46￣ 16. 96),Fe 34. 37(31. 06￣36. 50),T14. 74 (4. 42￣ 5. 14), totaling 99. 65. Chemical formula is Fe2 (As, S )5. The strongest lines(um) in the X-ray diffraction pattern are: 200, 2. 720 (90); 210, 2. 440 (90); 21 , 2. 230 (70) ;220, 1. 925(50); 311, 1. 641 (100); 511, 1. 048 (40). Isometric system of the sample is: Pa3,α= 5. 44±0. 002um,Z =4.
