摘要
地质熔体/流体是地球深部物质交换和能量传递的重要载体,其连通性主要用二面角来表征,实验研究地幔熔体的连通性对深刻理解地球深部熔体/流体的聚集、迁移、岩浆演化、早期核幔分异、解释地球物理观测到的低速高导异常等科学问题具有重要意义。本文对地幔熔体连通性的理论基础、静态和动态条件下各种影响因素(温度、压强、成分、挥发分等)对部分熔融体系中硅酸质和碳酸质熔体以及金属熔体连通性影响的实验研究进展以及在地球科学研究中的一些应用进行了简单介绍和回顾,旨在让国内更多学者对这一研究领域有更深入全面的了解。
Geological melt/fluid is an important carrier of material exchange and energy transfer in the Earth s interior,and its connectivity is mainly characterized by dihedral angle.Experimental study on the connectivity of mantle melt is of great significance for a comprehensive understanding of the accumulation and migration of mantle melt,magmatic evolution,core-mantle differentiation in early Earth,and interpretation of geophysically observed low-velocity and high-conductivity anomalies.This paper briefly introduces and reviews the theoretical basis of mantle melt connectivity,research progresses of various influence factors(temperature,pressure,composition,volatile,etc.)on the connectivity of melts(including silicate,carbonate and metallic melts)in partially molten system under static and dynamic conditions,and some applications in geoscience.The main purpose of this review is to let more domestic scholars have a deeper understanding of this field.
