摘要
孤山子超镁铁质岩体是冀东地区重要的磁铁矿源之一,同时也拥有较好的铜镍矿床的成矿条件。流体包裹体的研究表明,该铜镍矿床的流体包裹体主要有3种类型：气液两相包裹体（个别为纯液相包裹体）、富CO2三相包裹体和纯气相包裹体。孤山子铜镍矿床的成矿流体属于中低温、中盐度和中低密度的酸性流体,形成深度约为8.5~9.8km,成矿流体压力约为106~138MPa。
Gushanzi ultrabasic rock mass is one of the important source ot magnet in Hebel eastern, wmcn has good metallogenic conditions of copper--nickel. Studies on fluid inclusion show that there are three major types of fluid inclusion, gas--liquid inclusions （individual pure liquid inclusions）, rich CO2 three-- phase inclusions and pure gas inclusions. Gushanzi copper--nickel deposit ore-forming fluid belongs to a- cidic fluid of mid--low temperature, middle salinity and mid-low density, which formed under the depth of about 8.5 - 9.8 kin, and the pressure of ore-forming fluid was between 106 and 138 Mpa.
