| 摘 要： | 研究地幔矿物的电导率可以揭示地球内部电导率的分布规律以及地球介质的极化机制。通过对近年来国际上地幔矿物电导率的研究结果进行分析和总结,介绍了矿物的各种影响因素与电导率的关系;对含水和不含水的地幔矿物导电机制进行了区别,不含水矿物的导电机制主要为小极化子,含水矿物的导电机制为自由质子。比较了各种典型的地幔矿物电导率结果并对电导率模型进行了评述和总结,对电导率的研究方向进行了展望。认为水在地幔矿物电导率和电导率剖面中起着重要作用

| Abstract: | The knowledge of electrical prosperities of mantle minerals can help us to learn the distribution of the electrical conductivity in the interior of the earth and the polarization mechanism of the earth's material.The experimental results of electrical conductivity of mantle minerals were summarized and analyzed.We reviewed several important influential factors on the electrical conductivity of mantle minerals.The conduction mechanism of dry mantle minerals is different to that of wet mantle minerals.There is a small polaron conduction mechanism for dry mantle minerals,however,the conduction mechanism of wet mantel minerals is attributable to free proton.The results of typical electrical conductivity of mantle minerals were plotted and compared,and several electrical conductivity depth models were also introduced.We concluded that the water should play an important role in the electrical conductivity and the conductivity depth models.At last,we also point out the prospects of research in the future. |
