摘　　要：通过详实的野外地质调查,查明了皖南歙县双河口地区砚石板岩矿床的赋矿地层及成矿地质条件。砚石矿是层控型浅变质沉积岩矿床,赋存于新元古代大谷运组上段黑色板岩中。通过系统的室内岩矿鉴定和分析测试,查明了砚石的矿物组成、结构构造及砚石板岩的化学组成。通过野外放射性测量,判定该天然矿石放射性辐射属于安全等级,为皖南地区砚石资源开发提供了科学依据。Through a detailed field geological survey, this paper investigated the strata and minerogenetic conditions of the inkstone slate mine in Shuanghekou district of Shexian in southern Anhui Province. The inkstone deposit is a stratabound-type metamorphic-sedimentary deposit occuring in black slates of the upper Daguyun Formation of Neoproterozoic era. A systematic indoor rock-mineral determination and analytical test reveal the mineral composition, structure and chemical constitutions of the inkstone slates. In addition, field radioactive measurements show that radiation of the natural ore is at a safe level, thus providing scientific basis for the exploration of inkstone resources.
