Imaggeo On Monday: Hedenbergite – Ilvaite skarn, Calamita, Island of Elba

In this photo taken on the Isle of Elba in Italy you can see several radiating crystals of greenish Hedenbergite, inter-grown with blackish coloured Ilvaite in skarn bodies. Skarn is an unique formation that formed as a result of the interaction between geothermal fluids and the host rock. In this case the geothermal fluids come from the Late Miocene Porto Azzurro monzogranite, and Mesozoic marble ...[Read More]

InterArctic project: understanding the interaction between artic environments and societies

The InterArctic project (Fig. 1) focuses on vulnerability, resilience and adaptation of northern societies facing global change. The current rapid warming of Arctic and Subarctic climates has already produced many changes in the social, economic and cultural behaviour of the populations inhabiting these regions and more changes are expected to come. In this context, looking at the past provides th ...[Read More]

Colour deficient vision and the geosciences; just another way of looking at things

Colour deficient vision and the geosciences; just another way of looking at things

Like a reasonably large proportion of the population, I have colour vision deficiency (also known as colour deficient vision or colourblindness). I’m not going to get into the technical aspects of what this is like as they are covered well here and here, and you can do an Ishihara test, and other tests here, to check your own vision. The other reason I’m not going to discuss the technicalities of ...[Read More]

Imaggeo On Monday: Emoji from meteorites; impact spherule

This is a crossed polarized light photomicrograph of an impact spherule; a small mineralisation made when a meteorite hits the Earth and melts the rock at the point of impact, from Barberton Greenstone Belt, in South Africa. These spherules are the only remnants of Early Earth’s meteorite impact history, from between of 3.2 and 3.5 billion years ago. In this photo you can see the K-feldspar ...[Read More]

GeoTalk: Nadine Gabriel, creator of #AreYouSiO2? and Assistant Curator of Fossil Mammals.

Hi Nadine, thanks for speaking with us today, can you tell us a little bit about your background and how you got to where you are now? Thank you for inviting me! I’m a geologist and the Assistant Curator of Fossil Mammals at the Natural History Museum, London. I studied MSci Geology at University College London and I absolutely enjoyed the subject. It was really interesting to learn about the geol ...[Read More]

Climate models and Bach’s unfinished fugue

Climate models and Bach’s unfinished fugue

Johann Sebastian Bach’s last work – Contrapunctus XIV – is an unfinished musical composition. For many years, scholars considered that this piece was left unfinished because of Bach’s deteriorating health in his final years and eventual death. However, researchers recently found evidence that Bach might have left this piece intentionally unfinished, as he thought that there was still room for impr ...[Read More]

The two faces of Mars

The two faces of Mars

In this week’s blog post, we will learn more about the past of our neighbouring planet Mars. Kar Wai Cheng, PhD student at the Institute of Geophysics at ETH Zurich, is talking about the Martian dichotomy and how it could have formed. Humans have recognized Mars for a very long time. One of the earliest records of Mars is seen on a skymap in the tomb of an ancient Egyptian astronomer. By tha ...[Read More]

Water Researchers of Color experts in their fields

The Water Researchers of Color (WaterPOC) database is a resource that aims to add to numerous efforts in the last year to raise awareness of Black, Indigenous, and people of color (BIPOC*) in science, in this case specifically multiple disciplines intersecting with water. This resource mirrors many others, such as 500 Queer Scientists and 500 Women Scientists and numerous other databases [1], whic ...[Read More]

The Challenges of Being LGBTQIA+ in Earth Sciences

The Challenges of Being LGBTQIA+ in Earth Sciences

Did you know that political leaders in some European countries declare LGBTQIA+ as a totalitarian “ideology” that is “worse than communism” or compare gay adoption to pedophilia? This may sound unimaginable these days but those are statements that were proclaimed just recently, within the past years! The ILGA Europe publishes a review of the human rights situation of LGBTQIA+ people in Europe each ...[Read More]

Imaggeo On Monday: Condensation drop on sulphur

Mineralogy, as a subject, often has a hard time. Despite it’s place at the core of the traditional geological sciences, and its importance in a huge variety of other subjects, mineralogy sometimes has a reputation of being complicated and inaccessible and, well, some people have even called it boring. This is also related to the way that minerals are often hugely misunderstood by non-geoscie ...[Read More]
