The Invisible Brake: Near-Surface Cooling Stalls Giant Dyke Swarms
Introduction: Unveiling the Hidden Controls on Giant Dyke Swarms Giant dyke swarms are among Earth’s most striking geological features: networks of long, sheet-like cracks that channel molten rock laterally through the crust. These structures play a pivotal role in how magma intrudes, migrates, and eventually erupts. Recent insights, distilled from the Journal of Geophysical Research:…

The Invisible Brake: How Near-Surface Cooling Stalls Giant Dyke Swarms
The Hidden Brake on Magma: Near-Surface Cooling and Dyke Swarms Giant dyke swarms are among Earth’s most striking subterranean features: networks of long, sheet-like cracks that channel magma sideways through the crust, helping shape volcanic landscapes and crustal evolution. A recent synthesis from the Journal of Geophysical Research: Solid Earth highlights a surprising factor in…
