Near-Surface Cooling Stalls Giant Dyke Swarms in Crust
Understanding Giant Dyke Swarms Giant dyke swarms are expansive networks of long, sheet-like cracks in Earth’s crust that channel magma laterally. These structures play a crucial role in how molten rock moves from deep reservoirs toward shallower levels, influencing volcanic behavior, crust formation, and mineral resource distribution. Recent research emphasizes how cooling near the surface…

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:…
