热与冰的交互作用把岩浆雾化成比通常的火山灰更为纯净的微粒,同时,它产生的蒸气云把火山灰送到了比通常更高的高空。
The interaction of heat and ice atomized the magma into much finer particles than is typical, and created a steam cloud that sent the ash higher than usual into the air.
他声称,之前普遍为大众接受的理论可能是错的——即当火山岩浆库冷却后,需要经过多年才能在新岩浆的作用下重新恢复高温。
He said the widely accepted theory that when a volcano's magma chamber cools it could be years before it heats up with fresh magma could be wrong.
原生裂缝是岩浆冷凝结晶过程中形成的裂缝; 次生裂缝是火山岩及其原生裂缝系统受后期构造运动、溶蚀、风化等作用改造而形成的裂缝。
Primary fracture were formed during the lava crystal and the secondary fracture generated during the volcanic reconstruction by tectonic movement, and wind action, solution.
