A new tool for the interpretation of palaeomagnetic data
As part of my PhD research, I spent quite a lot of time at the Fort Hoofddijk (informally known as The Fort) – the palaeomagnetic laboratory of the University of Utrecht (in the Netherlands). For a little insight into what carrying research out in a 19th Century bunker, housed within the grounds of the botanical …[Read More]
Crocodiles feeling the heat of extinction
New research on crocodiles shows that a combination of changing sea levels and temperatures were responsible for driving their biodiversity over millions of years. Living crocodiles are threatened by climate change, with 10 out of 23 species at a high risk of extinction. As ectotherms, animals which require external sources of heat to function, they …[Read More]
Geology Photo of the Week #47
This week’s photo is another mineralogy themed one. This photo shows beautiful, yet also flattened crystals of the mineral natrolite that has grown in an acicular habit from a central point making them look sort of like little snowflakes. Natrolite is a relatively common hydrated sodium, aluminum silicate mineral (Na2Al2Si3O10 · 2H2O) that often forms within the …[Read More]
The Mexico City earthquake, 19 September 1985
As a volcanologist based in the UK, I am in the privileged position of rarely being affected by the natural events that I study. And, although I have worked for extended periods of time in earthquake-prone regions, I have never experienced anything more than the gentle nudge of a small tremor. Thirty years ago, shortly …[Read More]
Maria Graham, and a large earthquake in Chile, 1822
As news comes in of another very large earthquake in Chile – the third magnitude 8 earthquake along Chile’s Pacific margin in the past six years – this is a stark reminder of the destructive potential of these extreme natural events. These days we are used to the rapid, or near-real-time diffusion of news as these …[Read More]
ATTA and the Curious Case of Krypton-81
Ok, so I took some license with the title. This isn’t really a curious case and neither Krypton-81 nor ATTA are actually people. In fact, Krypton-81 (81Kr) is a radioisotope of the noble gas krypton and ATTA, which stands for atom trap trace analysis, is the revolutionary technique that has made its analysis possible. I …[Read More]
Nessie dwarfed by new Scottish crocodile
Yes, Nessie had to be in the title. Am I sorry? A little. But not enough to not use it. Colleagues from the University of Edinburgh and myself have described the first Scottish crocodile fossil! It’s from the Isle of Skye, from a time known as the Middle Jurassic, and dates back around 160 million …[Read More]
