| 摘 要： | 本文评述了岩浆物理性质和流体动力学应用于火成岩岩石学研究的新进展，并强调了其地质成果。岩浆的密度和粘度是岩浆两个最重要的物理性质，岩浆密度和粘度的变化对岩浆流体动力学习性以及产生火成岩的多样性起了重要作用。岩浆房中的双扩散对流、岩浆房的再充填以及边界作用等是岩浆流体动力学的重要机制，对它们的研究，使人们对火成岩的成因和演化以及地球动力学产生了新的认识。本文还概述了流体动力学机制的主要地质结果，如：地幔对流、成矿作用、带状岩浆房、层状侵入体以及火山岩中的流体动力学等。但直到目前，岩浆流体动力学机制及其应用仍是一个崭新的研究领域。

| Abstract: | This paper reviews advances in the application of magmatic physical propertiesand fluid dynamics in igneous petrology.Changes in density and viscosity,importantphysical properties of magma,play major role in its fluid dynamics and in the productionof a variety of igneous rocks. Double diffusion convection and refilling in magma cham-bers,and also the border effect are important mechanisms of magmatic fluid dynamics.Bystudying them,scientists have produced new ideas on the genesis,evolution and geodynamics of igneous rocks.These key achievements of fluid dynamics are briefly discussed:convection in the mantle,mineralization,zonal magma chambers,layered intrusion andfluid dynamics in volcanic rocks,The mechanisms of magmatic fluid dynamics and theirapplication are a very new domain. |
