How Stress Biaxiality Controls Crack Morphology and Apparent Fracture Energy of Dikes and Sills. Journal: Geophysical Research Letters Published: 2025-02-28 DOI: ...

Late in the basin’s history, rift sediments were intruded by mafic magmas that crystallized into diabase dikes and sills in the subsurface and basalt flows on the surface. These igneous rocks formed ...

Volcanic eruptions occur when bubbles of gases such as SO 2 and CO 2 rise to the Earth’s surface through dikes and sills in the planet’s crust, bringing hot, molten rock known as magma with them. To ...

Dikes cut across the beds of rock while sills are injected parallel to the bed, he said. But that wasn't all that affected the rocky coast of Ogunquit; ...

Over the past six decades, Manitoba has developed a complex network of dikes, dams and ditches to keep water flowing to its destination without harming Winnipeg, Brandon and many other communities.
