岩浆在地球中的迁移是一种对地球的物理、化学和气候演化具有头等重要性的现象。特别是火山活动，不仅对环境造成直接影响，而且对气候产生长期影响，对人类生活产生巨大影响。近几十年来，岩浆的输运特性，即对应力的物理流动和化学梯度导致的溶解组分的扩散，一直是深入研究的主题。然而，这些物理和化学反应的复杂性需要一个更普遍的图片岩浆运输比目前可用的。新兴的观点认为，岩浆输运融合了熔体动力学，非牛顿流动，脆性破坏，以及玻璃态和液态的基本性质。
The transport of magmas in the Earth is a phenomenon of first-order importance to the physical, chemical, and climatological evolution of our planet. Volcanism, in particular, can have dramatic impact on human lives, not only as an immediate environmental hard but also as a longer-term influence on climate. The transport properties of magma-that is, physical flow in response to stress and diffusion of dissolved components as a result of chemical gradients-have been the subject of intensive study in recent decades. Nevertheless, the complexity of these physical and chemical responses require an even more generalized picture of magma transport than is currently available. The emerging view of magma transport incorporates melt dynamics, non-Newtonian flow, brittle failure, and the fundamental nature of the glassy and liquid states.
