在第四纪，西欧的板块内火山活动在统计学上具有显著的偶然性。通过比较法国和德国已知的火山喷发年龄，我们研究了过去200万年中间歇性火山活动与气候记录之间的联系。研究表明，415-400 ka和17-5 ka之间的火山活动增加与末魏希塞利世（deven世）末和早期埃尔斯特世（Anglian）冰期末的增温阶段有关。德国艾菲尔东部的三次重大火山口爆炸都与间冰期开始时的变暖阶段有关。附近冰盖的生长和衰减表明，冰川米兰科维奇旋回期间大陆块体分布的表面变化可能通过岩石圈弯曲载荷的远端影响为这种相关性提供了一种机制。版权所有©2006约翰威利父子有限公司
Intra‐plate volcanism in western Europe shows statistically significant episodicity during the Quaternary period. By comparing the known ages for eruptions in France and Germany, which are compiled here, with a composite oxygen isotope record, we have investigated the link between this episodic volcanism and the climate record over the last two million years. We show that increased volcanism between 415–400 ka and 17–5 ka correlates with warming phases at the end of the last Weichselian (Devensian) and earlier Elsterian (Anglian) glacial stages. The three significant caldera explosions in the eastern Eifel, Germany, are all associated with warming phases at the onset of interglacials. The growth and decay of nearby ice sheets suggest that surface changes in continental mass distribution during glacial Milankovich cycles could provide a mechanism for this correlation by means of the distal effects of flexural loading on the lithosphere.
