摘　　要：广东宝山嶂铁矿属于接触交代热液型铁矿,黑柱石产于该矿区Ⅲ号磁铁矿矿体边部与矽卡岩的接触部位。本文研究了该矿区黑柱石的矿物成分、XRD特征以及矿物共生组合关系,根据黑柱石的产出形态和矿物共生组合关系,把该矿区产出的黑柱石分为2个世代:第1世代黑柱石与透辉石共生,自形程度较差,为致密块状集合体;第2世代黑柱石与石英、方解石共生,自形程度较好,多为柱状或粒状。Baoshanzhang iron deposit is the contact metasomatism and hydrothermal iron ore deposit, the ilvaite occurred in contact zone between the edge of the HI magnetite ore body and skam. The paper researched the ilvaite＇s mineral composition, XRD and mineral paragenesis, according to the ilvaite＇s form and mineral paragenesis, classified the ilvaite into two generations： the first generation is occurred with diopside, which has poor crystalized, dense massive collections： the second is mainly coexisting with quartz, sometimes is also with calcite, which has better crystalized, mainly prismatic and granular.
