太白金矿黄铁矿热电性及其在找矿中的应用

Pyroelectricity of Pyrite and Application to Prospectingin Taibai Gold Deposit

通过载金矿物黄铁矿热电性研究，得出本区黄铁矿以P型和N－P型导电为主．P型含量高及高的热电系数绝对值指示有利于金矿化，并由此推测可能的有利成矿部位．双王成矿带从西向东，其N型出现率从高到低，反映了从西向东矿体的剥蚀率从大到小，根据黄铁矿热电系数计算得出的热场分布与石准立等（1989）利用含铁白云石中包体均一法测温所得出的温度场相同，对黄铁矿热电性与赋矿围岩之间对应关系及可能原因也进行了讨论。

Studies on pyroelectricity of pyrite have been made in taibai gold deposit， ShannxiProvince. Pyrite occurs maily N-P-type and p-type electricity conduction (N-electronic conduction，p-hole conduction). High P-type content and high absolut value of pyroelectricity coefficient indicated the good mineralization.From upper to lower of the ore body， from west to east of the orebelt， the P-type content is going down.That shows the denudation rate of ore body from large tosmall. Contour map of absolute value of pyroelectricity coefficient and isothermal map calculatedfrom pyroelectricity shows that the deep and east of KT8 is the prospective ore area.The pyroelectricity differs with the kind of wallrock that may be result of the difference of deep of ore-forming.
