摘要
黄铁矿是五龙金矿的主要载金矿物之一 ,热电性以P型为主 ,占总数的 90 8% ,变化范围为 4 3～ 392 0 μV/℃ ,N型占 9 2 % ,变化范围为 - 2 8 6～ - 177 1μV/℃ ;不同世代黄铁矿热电性不同 ,第一世代为P型 ,第二、三世代为P、N混合型 ;横向上从矿体到围岩 ,热电系数由小变大 ,纵向上由矿体头部到尾部 ,热电系数由大变小 ;黄铁矿热电性主要与杂质元素As、Co、Ni相关 ,As使其呈P型 ,而Co。
Pyrite is one of the main Au Carrying minerals in the Wulong gold deposit. The main type of Pyroetectricity is P, whose ratio to gross number is 90 8%, and the variable range is from 4 3 to 392 0 μV/℃, the ratio of N is 9 2%, its wide range is from -28 6 to -177 1 μV/℃;the Pyroelectricity of pyrite from different generations is different,the first generations is P,the second and third generation is the mixture of P and N; on tranverse, Pyroelectricity factors increase from ore body to wall rock; however, on vertical, Pyroelectricity (factors of pyrite) decrease from head of Ore body to tail. Pyroelectrcity of pyrite is correlative with impurity elements such as As、Co、Ni. As makes it P, and Co、Ni make it N.
