With rocks dating as far back as the Precambrian, mountain building events, violent volcanic eruptions and being covered, on and off, by shallow seas, Death Valley’s geological history is long and complex. Back in the Cenozoic (65 to 30 million years ago), following a turbulent period which saw the eruption of volcanoes (which in time would form the Sierra Nevada of California) and regional uplift ...[Read More]
The best of Imaggeo in 2016: in pictures
Imaggeo, our open access image repository, is packed with beautiful images showcasing the best of the Earth, space and planetary sciences. Throughout the year we use the photographs submitted to the repository to illustrate our social media and blog posts. For the past few years we’ve celebrated the end of the year by rounding-up some of the best Imaggeo images. But it’s no easy task to pick which ...[Read More]
GeoEd: A round-up of (geo)educational board games
With the rise of electronic games – those played on computers, consoles and even on mobile phones – you’d be forgiven for thinking the humble board game would be slowly making its way into the history books. Nothing could be further from the truth! Sales of board games are on the up, as are cafes where you can gather to play table-top games of your choice, and board game meet ups: regular gaming g ...[Read More]
Imaggeo on Mondays: The odd ‘living’ rocks
Microbialites – structures which result from the interaction between microbes and sediments – have existed in the rock record since 3700 Ma ago until the present day. The presence of microbes in environments where mineral precipitation is prevalent, usually derives in the development of such chemical sedimentary structures. This can take place in marine, non-marine, and subterranean environm ...[Read More]
Celebrating Earth Science Week!
For those not so familiar with the Earth sciences, geosciences and all its subdisciplines might be shrouded in mystery: boring, unfathomable, out of reach and with little relevance to everyday life. Nothing could be further from the truth! Earth Science Week, an international annual celebration founded by the American Geosciences Institute in 1998, aims to change the public’s perception of the ge ...[Read More]
Imaggeo on Mondays: The road to nowhere – natural hazards in the Peloponnese
The Gulf of Corinth, in southern Greece, separates the Peloponnese peninsula from the continental mainland. The structural geology of the region is complex, largely defined by the subduction of the African Plate below the Eurasian Plate (a little to the south). The Gulf itself is an active extensional marine basin, i.e., one that is pulling open and where sediments accumulate. Sedimentary basins r ...[Read More]
Who do you think most deserves the title of the Mother of Geology?
Much ink is spilled hailing the work of the early fathers of geology – and rightly so! James Hutton is the mind behind the theory of uniformitarianism, which underpins almost every aspect of geology and argues that processes operating at present operated in the same manner over geological time, while Sir Charles Lyell furthered the idea of geological time. William Smith, the coal miner and canal b ...[Read More]
New study of natural CO2 reservoirs: Carbon dioxide emissions can be safely buried underground for climate change mitigation
New research shows that natural accumulations of carbon dioxide (CO2) that have been trapped underground for around 100,000 years have not significantly corroded the rocks above, suggesting that storing CO2 in reservoirs deep underground is much safer and more predictable over long periods of time than previously thought, explains Suzanne Hangx a postdoctoral researcher at the University of Utrech ...[Read More]
Geosciences Column: Pollen tells a 7300 year old story of Malta’s climate and vegetation
Figuring out what the climate was like, and how it changed, throughout Earth’s history is like trying to complete a 1000 piece puzzle. Except that scientists usually don’t have all the nuggets and building a comprehensive picture relies on a multidisciplinary approach in order to fill in the blanks. This is particularly true during the Holocene, which spans the last 11,700 years of the Earth’ ...[Read More]
Livers, guts and gills: understanding how organisms become fossils
It’s 10am and Thomas Clements, a 3rd year palaeobiology PhD Student, is getting ready to check on his latest experiment. Full kited up in what can only be described as a space suit, Thomas carefully approaches the fume cupboard home to his latest specimen: a decaying seabass, balanced on a specially designed ‘hammock’ in a tank of salty water. Opening the lid to check on the rotting fish, Thomas i ...[Read More]
