四川大水沟碲矿床是世界唯一的独立碲矿床，楚碲铋矿是该矿床中重要的碲矿物之一。它存在于辉碲铋矿和磁黄铁矿晶粒之间，或包裹在辉碲铋矿中。呈银灰色，金属光泽，一组底面解理发育。显微压入硬度为80．5kg／mm2（15g负荷）。反光显微镜下为白色，非均质性清楚，反射率为58．0～59．9（λ=546nm）。X射线粉晶衍射分析的主要谱线有：4．797（60），3．229（100），2．368（80），2．169（50）。矿物的化学组成据11个电子探针分析的平均值为（重量％）；Fe0．13，S0．04，Cu0．03，Te37．84，Bi61．37，Se0．01，Sb0．16；总量99．58，其化学成分式为；BiTe。楚碲铋矿形成于贫硫环境中。
The Dashuigou tellurium deposit in Sichuan is the only independent tellurium deposit in the world, and Chu-tellurite ore is one of the important tellurium minerals in this deposit. It exists between the telluride bismuth ore and pyrrhotite grains, or wrapped in telluride bismuth ore. Was silver-gray, metallic luster, a group of bottom cleavage development. Micro-micro-hardness of 80.5kg / mm2 (15g load). Reflective microscope is white, the heterogeneity is clear, the reflectivity of 58.0 ~ 59.9 (λ = 546nm). X-ray powder diffraction analysis of the main spectral lines are: 4.797 (60), 3.229 (100), 2.368 (80), 2.169 (50). The chemical composition of the minerals is based on the eleven electron probe analysis (wt%); Fe0.13, S0.04, Cu0.03, Te37.84, Bi61.37, Se0.01, Sb0.16; 99.58, its chemical composition formula; BiTe. Chu tellurite ore formed in the sulfur-depleted environment.
