摘　　要：磁黄铁矿是老柞山金矿的主要载金矿物 ,矿区大量产出的为早成矿期的六方磁黄铁矿 ,生成于弱还原、弱酸性的环境中 ,形成温度约 35 0℃± ,其Fe空位较大 ,晶胞参数与标准值相比较 ,a0 较大 ,c0 则较小 ,热电系数值较小 ,且数值稳定 ;晚成矿期产出的磁黄铁矿较少 ,为六方磁黄铁矿与单斜磁黄铁矿的混合物 ,形成温度小于 30Pyrrhotite is the main gold carrying minerals.Most Pyrrhotites are present in the form of hexagonal system which occurred in early mineralization period in the faint reduction and acid environment and their forming temperature is about 350℃.Fe vacant site is large.Comparing parameter of crystal cell with standard value, a 0 is large,while both c 0 and thermoelectricity factor are small with stable values.pyrrhotite which occurred in the late mineralization period is less.It is the mixture of hexagonal and monoclinic system pyrrhotite whose forming temperature is less than 300℃.
