Rocks in the right place at the right time…

Flo looks two examples of the strange and important ways that geology and where it’s located can affect international governance and regulation. From the presence of tiny coralline islands to ownership of the Arctic! I’ve always had an interest in the peculiarities of geology and geomorphology and the inordinate (sometimes almost absurd!) ways that they play their part in deciding on big international governance. Humanity has long-relied on the presence of geological features such [...]

 Cambrian; GB
Adam Sedgwich (March 22, 1785 - January 27, 1873) was an English geologist who first applied the name Cambrian to the geologic period of time, now dated at 570 to 505 million years ago. In 1818 he became Woodwardian Professor of Geology at Cambridge, holding a chair that had been endowed ninety years before by the natural historian John Woodward. He lacked formal training in geology, but

Images of Guatemala (9) – Conflict and Disasters 

Geology for Global Development [2015-01-23 10:00:20]  recommend  recommend this post  (28 visits) info

Until 1996, Guatemala was in the midst of a brutal Civil War. This sculpture in the Presidential Palace of Guatemala City is a reminder of that troubled past and symbolic of a hopeful peaceful future. In the same way that conflict/disasters can hamper and set-back development efforts, conflict can also set-back disaster risk reduction and management. Even once finished, past conflicts can erode trust between different groups. High levels of trust are a crucial factor in both preparing for [...]

A cool new ichthyosaur – a type of marine reptile – has just been named in the Scottish Journal of Geology. I’ve written about it here, with some great comments from the lead author (Steve Brusatte). Most reports on the new beastie just focus on the finding, but we’ve gone for a different angle by delving into what it means for the evolution of ichthyosaurs during the Jurassic period. Enjoy!

Russia's Underappreciated Contribution To The Geosciences

Nature Geoscience has a short editorial that pays tribute to Russia's scientific legacy, more specifically that in geology. Political differences and language barriers have isolated Russian science and scientific literature from the rest of the English speaking science community. Consider this: Lomonosov is the author of one of the most important treatises of geology that those of us who

I'm going to be taking some time off for the holidays. But before I go, something trivial to enjoy in my absence: Someone pointed me to the uncyclopedia entry for "geologist" a while back. It's pretty amusing, although many of the jokes are getting old at this point. Geologists love beer? Whoda thunkit? I will admit, however, that some stereotypes have a kernel of truth.

That spiral cut ham–scalloped potatoes–pecan and cranberry dressing–vegetable medley–cranberry sauce–two pieces of pie–champagne and wine Thanksgiving dinner needed to be dealt with.

Geologists, do you trespass? Do you chase your outcrop over hill and dale? Sneak over a fence to collect a nice rock specimen? I do not. I'm pretty careful about lining up my permissions and access agreements. Even when a resident tells me straight out to just let myself in and not bother them with notifications, I still send a reminder before I go, and once I'm done with my sampling, leave | Impressum
