Fossil fuels are typically generated within buried organic-rich sediments over long geological timescales. However, these processes may be accelerated when the sediments are exposed to migrating magmatic fluids, such as those related to nearby volcanic activity. A new international collaborative study in Scientific Reports led by CEED PhD student Alexandra Zaputlyaeva including CEED researchers Adriano Mazzini and Morgan Jones, investigates the ongoing reactions below the largest active mud eruption on Earth – Lusi - located in north-east Java (Indonesia). Results reveal that hydrocarbon generation is occurring ~4.5 km below Lusi and that this is largely driven by the recent magmatism.
Earth’s relief is in continuous change; mountains are eroded by wind and water, the valleys, seas and oceans are filling up with the scoured sediments, and the continents get thinner or thicker during these processes. But this is not all! Deep down, sometimes hundred of kilometres from the surface, much slower forces at work carving the continents upside down. New work published in Nature Communications reveals just that for Africa!
