摘要
应用物理原理研究不同规模和时间尺度火山活动的动力过程,近年来不断受到中国火山学者的关注。过去几年,中国第四纪火山区内火山活动的物理过程研究取得了一些有价值的进展。本文重点总结和评述了岩浆房的固结、分离结晶和活动稳定性、火山通道和喷发柱的动力学、火山碎屑流与熔岩流运移与就位的物理过程。对火山碎屑物与熔岩流的分形特征以及岩浆房的动力系统中存在的非线性过程进行了特别的评价和展望。
Many significant progresses were obtained on the physical processes of volcanic activities in the Quaternary volcanic area in China during the past few years.The physical processes of solidification,fractional crystallization and stability of magma chambers,the dynamics of volcanic conduits and eruption columns,and the transport and emplacement of pyroclasts and lava flows are addressed and reviewed.The fractal characteristics of pyroclasts and lava flows and the nonlinear processes existing in the dynamic system of magma chambers are commented,especially.
