电导岩石学是国际地学界近年来新发展起来的一门交叉性和综合性很强的学科,主要是通过高温高压实验,在有效控制温度、压强、成分和氧逸度等参数的条件下,对硅酸盐矿物的电导率进行测定,并把有关结果和地球物理学电磁探测的结果相比较,从而为正确认识地球深部的组成、结构、性质和动力学过程提供制约.根据近年来的文献报道,本文综合评述了电导岩石学研究工作的主要原理和方法,并就下地壳、上地幔、地幔过渡带、下地幔和核幔边界一些主要组成矿物电导率的实验测定进展及其对深部地球电导结构的制约进行了介绍.
Conductance petrology is a newly developed interdisciplinary and highly integrated discipline in the international geosciences. It is mainly through high temperature and high pressure experiments, under the conditions of effective control of temperature, pressure, composition and oxygen fugacity parameters, The conductivity of silicate minerals is measured, and the results are compared with the results of geophysical electromagnetic detection, so as to provide a theoretical basis for the correct understanding of the composition, structure, properties and dynamics of deep earth. According to the literature in recent years Reported that in this paper, the main principles and methods of conductance petrology were reviewed. The progress of the experimental measurements of conductivity of some major minerals in the lower crust, upper mantle, mantle transition zone, lower mantle and the boundary of the mantle and its influence on deep earth Conductivity structure of the control were introduced.
