| 摘 要： | 作者的研究表明,在非本征激发区,矿物热电系数随着活化温度的增高而增大;在本征激发区,随活化温度的增高而减小。矿物晶体中所含杂质的种类和含量多少决定矿物的导电类型。矿物热电系数可广泛应用于地质找矿和矿床评价中,以黄铁矿为例,在同一水平面上的含金矿脉,矿脉中黄铁矿热电系数正值高时,其矿石含金量也高。应用黄铁矿热电系数的正高值、混合型和负值可确定矿体和矿体的剥蚀深度。

| Abstract: | Studies on thermoelectric coefficients of minerals show that they increase with increasing temperature activated in extrinsically exciting field and decrease with decreasing temperature activated in intrinsically exciting field.The conduction types of minerals are determined by the types and the contents of impurities in crystals. Thermoelectric coefficients of minerals,pyrite e.g,are widely applied to geologically prospecting and evaluating deposits. When the thermoeletric coefficient of pyrite within gold veins on the same horizontal plane are high positive, the contents of gold in ores are determined to be high too. So according to the types of thermoelectric coefficients: high positive, negative or both of them, orebodies and denuded depth can be delineated. |
