| 摘 要： | 通过对烟台南张家金矿黄铁矿的形态、成分和热电性标型的分析和测试 ,对金矿的深部成矿远景进行了评价。南张家金矿黄铁矿的形态以 { 1 0 0 } +{ 2 1 0 }为主 ,反映了成矿溶液中硫浓度较高 ,金具有明显的亲硫性。黄铁矿成分贫 Co、Ni,富 As、Hg。热电导型主要为 P型 ,表明所采矿体为浅部矿 ,深部仍有远景。同时 ,黄铁矿 P型导型出现率由上到下变化很小 ,成矿环境稳定 ,显示矿体向下继续延伸。另外 ,矿石中的黄铁矿与磁山二长花岗岩中的副矿物黄铁矿在形态、成分和热电性上具相似性 ,表明二者具有继承关系 ,佐证了金矿的形成与岩体的演化有关。 |

| Abstract: | Gold and silver minerals are closely related to pyrite in origin, and pyrite is a major gold bearing mineral.The deep mineral potential of gold is evaluated by analyzing and testing the form, composition and thermoelectricity of pyrite in the Nanzhangjia gold deposit.The form is mainly {100}+{210}, indicating the higher sulfur concentration in the mineralized solution, and the obvious sulfur affinity of gold; the composition is poor in Co and Ni, but rich in As and Hg; and the thermoelectricity is mainly P type, which accounts for 76%～100%, indicating the shallow deposit is being mined, and there is still a potential in depth.Meanwhile, the P type pyrite varies very little from top to bottom (0 03%～0 2% P type per meter), and the mineralized setting is stable, indicating the downward continuation of the mineral body.Additionally, there are similarities in form, composition and thermoelectricity between the pyrite in the deposit and the pyrite in the Cishan monzonitic granite, indicating their inheriting relationship between the two pyrites, and further indicating the formation of the gold mineral deposit is relative to the Cishan granite. |
