摘要
岩浆运移动力学是岩浆动力学的重要分支领域,研究内容包括5个方面:运移方式、运移通道、运移途径、运移动力与运移过程的成矿作用。就这5方面的研究进展进行了系统回顾,对尚待进一步研究的科学问题进行了归纳与总结,指出浮力不是弹性岩石圈岩浆运移上升的驱动力,而上地幔岩浆运移方式、弹性岩石圈岩浆往上运移驱动力、岩浆自主破裂形成的动力学机制、中途停歇岩浆重起动再运移的驱动机制、岩浆再停歇和运移过程的结晶与分异及其与围岩相互作用和伴生的元素富集与成矿作用等问题是岩浆运移动力学是尚待进一步攻关与研究的关键性科学问题。
Transport dynamics of magma is an important branch of dynamics of magma, and its research contents contain five parts, including transport pattern, path, channel, driving force and mineralization during transport processes. Advances of all the five contents are systemically reviewed,, and some potential important scientific questions are summarized, such as transport pattern of magma in the upper mantle, driving force for magma to ascent and formation mechanism of melt created fractures in elastic lithosphere, re-transport mechanism of magmas stagnated in chamber, and enrichment of elements and mineralization related to crystallization and differentiation of magma and interaction between magma and wall rocks during stagnation and transport processes of magma, in this contribution.
