Building the Earth in a sandbox

Fentale Volcano

  Building the Earth in a sandbox   The Main Ethiopian Rift stretches for hundreds of kilometers through Ethiopia, a massive fracture where Africa is slowly tearing apart to birth a new ocean. However, the processes driving this continental breakup remain hidden deep beneath layers of volcanic rock and millions of years of geological history. Today, in a laboratory in the heart of the be ...[Read More]

Cratons: building blocks of continents and their economic importance

Cratons: building blocks of continents and their economic importance

The 4.5 billion years of geologic evolution has shaped the tectonic processes in Earth we see today. Over the span of time, Earth has changed from being a magma ocean to a tectonically active planet, by transitioning through different tectonic regimes.  A silent witness of this journey have been cratons which have survived for billions of years. Therefore cratons preserve clues of past tectonic pr ...[Read More]

Destruction of the North China Craton and its global impact

Destruction of the North China Craton and its global impact

Cratons are forever, until they are not. These long-lived portions of lithosphere are known for being remarkably stable. However, if the conditions are right, even cratons can be ripped apart by geological forces, with far-reaching impacts on Earth’s systems. This week, Jyotirmoy Paul from the University of Oslo, Norway will tell us the downfall of the North China Craton, using numerical sim ...[Read More]
