The geothermal area Sol de Mañana is part of the Altiplano–Puna volcanic complex shared between Bolivia and Chile. The area is characterized by volcanic activity and the sulphur springs host mud lakes and steam pools. The different colours stem from thermophilic, hyperthermophilic and acidophilic bacteria that colonize areas of varying temperatures. Description by Julia Miloczki, …[Read More]
Each month we feature specific Divisions of EGU and during the monthly GeoRoundup we will be putting the journals that publish science from those Divisions at the top of the Highlights roundup. For January, the Divisions we are featuring are: Earth Magnetism and Rock Physics (EMRP) and Geochemistry, Mineralogy, Petrology and Volcanology (GMPV). They are …[Read More]
Hello Alessandro, thanks for joining us today! Before we delve deeper, could you tell us a little about yourself and your research? Hi, thank you for having me today, I am Alessandro Musu, a PhD student in Petrology and Volcanology at the University of Geneva. I have currently just started my third year. The main …[Read More]
The Križna jama Cave on the east side of the periodic Cerknica Lake in Slovenia is an underground karstic cave primarily famous as a rich site of bones of the extinct cave bear, Ursus speleus. The eight kilometer long cave is full of stalagmites and stalactites (sometimes called drip-stone decorations) and also boasts 50 underground …[Read More]
At EGU, we like to believe that a new year is more meaningful when we pause to look back at the year gone by – just a brief glimpse to appreciate all our good work and progress! 2021 was certainly an excellent year for our blogging network at EGU. Across the EGU’s official blog, GeoLog …[Read More]
Concomitant thrusting and magmatism resulted in the development of ductile mylonites in the Calamita Schists, part of the contact aureole of the Late Miocene Porto Azzurro pluton. This mylonite is made up of stretched and recrystallized quartz layers, interlayered with thin sericite-rich levels. Sericite resulted from the crushing of contact-metamorphic minerals such as andalusite, cordierite, …[Read More]
Where is Webb? This seemingly simple question is quickly making its way into everyday conversation, and not just in scientific and astronomy circles. After a long 32-year wait, NASA officially launched the James Webb Telescope a couple of weeks ago on 25 December 2021. More recently, the telescope deployed its final primary mirror segment on …[Read More]
It’s been well established that tsunamis generate magnetic fields as they move seawater (which is conductive unlike freshwater) through the Earth’s magnetic field. Although researchers previously predicted that the tsunami’s magnetic field would arrive before a change in sea level, they lacked the means to simultaneously measure magnetics and sea level to confirm this phenomenon. …[Read More]
Sometimes in order to test a theory about how processes work below the surface of the Earth, scientists need to recreate minerals found in very specific circumstances. This photograph was taken through a binocular microscope during a critical step of the creation of artificial peridotite: extraction of the artificial peridotite from its gold capsule. The …[Read More]
2021 was yet another year of uncertainty, with many changes and disruptions to our plans, activities, and goals. EGU’s science for policy programme was no exception to this with the Science for Policy Pairing Scheme and annual Science for Policy Event taking a back seat. We hope that 2022 will not only bring new activities …[Read More]
