蓝辉铜矿，英文名Digenite或Neodigenite。铜的硫化物矿物。主要产于中低温热液淋积及沉积等矿床中。 化学式：4Cu2S·CuS。
矿化具垂直分带，上部以蓝辉铜矿为主，标高580—400米间以硫砷铜矿为主。 400米以下以黄铜矿为主。
There are vertical zoning of mineralization, that is chalcocite in the upper, enargite at the elevation between 580 to 400m, and chalcopyrite below the 400m.
运用EPMA和SEM分析技术对辉铜矿和蓝辉铜矿木质细胞体的细胞核、细胞壁和细胞之间的成分变化、多种环境下的木质细胞形状进行了研究，对形成机理作了探讨。
By employing EPMA and SEM techniques we examined the compositions of nucleus, cell-walls and cells of wood-cytoplasm in chalcocite and digenite and the shapes of wood cells.
矿石主要含铜矿物为孔雀石、硅孔雀石，少量的黄铜矿、辉铜矿及极少量的斑铜矿和铜蓝等。
The main copper minerals are malachite, chrysocolla, little chalcopyrite, chalcosine and even little bornite and covellite.
