铬铋矿（Bi16．006Cr0．997O27）是在陕西省洛南县驾鹿金矿床中发现的一种新矿物。该矿物通常呈不规则状微细晶集合体，柱状小晶体大小在0．005mm×0．002mm～0．05mm×0．025mn。之间，集合体大小约0．01～0．5mm。呈桔黄或黄棕色，性脆，半透明，条痕棕黄色，金刚光泽，具不完全解理；一轴晶，正光性。实测密度为9．80（3）g／cm3。计算密度9．85（1）g／cm3。维氏硬度95．8～128kg／mm2，摩氏硬度3～4。折射率ω＝2．50（2），ε＝2．55（2）。15个电子探针平均成分Bi2O3为97．25％，CrO3为2．6％，总和99．95％，化学式：Bi16．006Cr0．997O27，理论式：Bi16CrO27。X射线粉晶衍射主要强线d（I）（hkl）为：0．319（100），（123）；0．273（40），（310）；0．198（40），（316）；0．1932（20），（420），0．1715（30），（219）；0．1655（55），（503，·433）。根据指标化求得铬铋矿为四方晶系，可能的空间群为I4，I4或I4／m；a＝0．8649（3）um，c＝1．724（1）nin，c／a＝1．9933；V＝1．2896（6）nm3，Z＝2。1－Kp／Kc＝0．025。铬铋矿作为新矿物及其命名已被国际矿物学协会新矿物和矿物命名委员会批准通过，其样品存放中国地质博物馆。
Chromite bismuth (Bi16.006Cr0.997O27) is a new mineral found in the Chalu gold deposit in Luonan County, Shaanxi Province. The mineral is usually irregular micro-crystalline aggregates, small columnar crystals in the size of 0.005mm × 0.002mm ~ 0.05mm × 0.025mn. Between the aggregate size of about 0.01 ~ 0.5mm. Was orange or yellow-brown, brittle, translucent, streaks brown, diamond gloss, with incomplete cleavage; axis of the crystal, is the light. The measured density was 9.80 (3) g / cm3. Calculate the density of 9.85 (1) g / cm3. Vickers hardness of 95.8 ~ 128kg / mm2, Mohs hardness of 3 to 4. Refractive index ω = 2.50 (2), ε = 2.55 (2). The average composition of 15 electron microparticles Bi2O3 is 97.25%, CrO3 is 2.6%, the sum of 99.95%, chemical formula: Bi16.006Cr0.997O27, theoretical formula: Bi16CrO27. The main d (I) (hkl) of X-ray powder diffraction is 0.319 (100), (123), 0.273 (40), (310), 0.198 (40), (316) 0.1932 (20), (420), 0.1715 (30), (219); 0.1655 (55), (503, .433). According to the indexization, the bismuthinite is tetragonal. The possible space group is I4, I4 or I4 / m; a = 0.8649 (3) um, c = 1.724 nin, c / a = 1.9933; V = 1.2896 (6) nm3, Z = 2.1-Kp / Kc = 0.025. Chromite bismuth ore as a new mineral and its nomenclature has been approved by the New Mineral and Mineral Nomenclature Committee of the International Association of Mineralogy and its samples are deposited with the China Geological Museum.
