| 摘 要： | 寨上金矿的金矿石稀土元素特征与容矿岩石相似,与侵入岩(二长花岗岩)的差别较明显,说明寨上金矿床成矿与地层建造具有成因联系.矿化带中明显富集Au,Hg,As,Sb,Pb,Zn黄铁矿中Co/Ni平均值为0.27～1.5,矿体的Co/Ni平均值为0.33～0.40,说明成矿温度不高.从赋矿岩石到金矿体Co,Ni值有增加的趋势,说明从沉积成岩到成矿,成矿元素及微量元素有进一步的富集. |

| Abstract: | REE characteristics of gold ore of Zhaishang gold deposit are similar to the sedimentary host rock,but differ from the intrusive rock(granite) nearby indicating that the ore is genetically related to the sedimentary stratum.Au,Hg,As,Sb,Pb,Zn concentrated in the mineralization zones and the average Co/Ni ratio 0.27-1.5 of pyrite and Co/Ni ratio 0.33-0.40 of orebody imply low metallogenic temperature and rising trend of the ratio from the host rock to the ore imply enrichment of the ore elements and trace elements from diagenesis to the ore formation. |
| Keywords: | REE trace element Zhaishang gold deposit Gansu provine |
