The geology of Venus presents a complex interplay between extensive volcanic activity, mantle dynamics and tectonic deformation. Recent studies have revealed that, in the absence of Earth‐like plate ...

A new analysis of rocks thought to be at least 2.5 billion years old helps clarify the chemical history of Earth's mantle -- the geologic layer beneath the planet's crust. The findings hone scientists ...

Geoscientists have discovered a new process in plate tectonics which shows that tremendous damage occurs to areas of Earth's crust long before it should be geologically altered by known plate-boundary ...

Boulder, Colo., USA: Marine and coastal geoscience play a critical role in understanding ancient and modern geological history, offshore and coastal hazards, and climate change. Deep-water ...

1. Introduction -- 2. Stress -- 3. Displacement and strain -- 4. Relation between stress and strain -- 5. Loading of brittle rock to failure -- 6. Stress concentration -- 7. Theories of brittle ...

Here’s what you’ll learn when you read this story: Mantle plumes are important geologic processes—they interact with plate tectonics, create rich mineral deposits, and even contribute to mass ...

Minerals are the fundamental components of Earth. Microbes occupy the majority of the tree of life. In near surficial environments, minerals and microbes co-exist and interact. The studies of ...

Are catastrophic geological events, like massive volcanic eruptions, random— or do they follow a specific cycle? It’s a question geologists have long asked, but one that’s been difficult to answer ...
