地幔矿物岩石的电导率研究进展

电导率高压测量技术的完善 ,使得人们在就位测量条件下获得了一系列地幔高压相矿物的电导率。由此 ,在回顾近几年地幔矿物岩石电导率的测量结果时 ,重点介绍了地幔高压相矿物的电导率研究。文中还介绍了根据地幔矿物岩石电导率数据而获得的电传导机制研究结果以及基于实验室电导率数据建立的电导率模型。近年来的研究结果表明 ,当在实验条件控制较好的高压装置上测量电导率时 ,实验室的电导率数据应该可以用来帮助电磁学家约束对野外数据的解释。

A REVIEW ON THE ELECTRICAL CONDUCTIVITY OF MANTLE MINERALS AND ROCKS

A series of important progresses on the electrical conductivity of mantle minerals and rocks have been made along with improvements of high pressure measurement techniques of electrical conductivity A survey of recent laboratory measurements of electrical conductivity of mantle minerals and rocks especial of high pressure phases is outlined The results of electrical conduction mechanisms and lab based conductivity models based on the conductivity data of mantle minerals and rocks are also presented The recent results show that laboratory conductivity data,measured with good control of the environment of the samples,can be used to constrain the results obtained by geomagnetists from the inversion of field data
