Over on her Georney‘s blog, Evelyn Mervine has recently posted a nice piece with some spectacular images of columnar jointing. This seemed like a good opportunity to dust off some field photos, with some more examples of polygonal joint sets in lavas from a variety of settings, to illustrate the diversity of forms that cooling-contraction joints may take in volcanic rocks. The first example ...[Read More]

Geoscience in the news
This is the fourth part of a series looking at how we should effectively communicate geoscience, based largely on a recent paper by Iain Stewart and Ted Nield. The previous post attempted to address the insanely impossible question of ‘who are the public?’, when it comes to public engagement’. It seems that this is very much a disciplinary issue, each with their own collective su ...[Read More]

Imaggeo on Mondays: Gullfoss, Iceland
For anyone who spent the 1980s jamming to British band Echo & the Bunnymen, this is a familiar sight. The cover of their third studio album, Porcupine (1983), features the band nonchalantly standing in front of the gushing white foam of Iceland’s Gullfoss waterfall. Mentioned in local written stories and beamed across the world in music videos, the Gullfoss falls occupy a mythical place in hum ...[Read More]

Geology Photo of the Week # 12 – Nov 18-24
Check out this beauty! AMAZING. Those crystals are a few centimetres in size, flawless and have a great colour. Unfortunately, I don’t remember where it came from. I know, I know, this is the cardinal sin, so I apologize for that. I hope you enjoy looking at it all the same. Cheers, Matt

Peering into dinosaur skulls – the best application for medical technology
Most of what we know about dinosaurs comes from their skeletal remains. Rarely, we get tiny glimpses into their soft tissue anatomy through skin impressions and even rarer, preserved tissue fragments, mummified over time, and their ecology and life habits through combining interpretation of this from what we can glean from trace fossils (footprints, poop, etc.). Palaeontologists are also taking th ...[Read More]

Who the devil are this ‘public’ everyone keeps rambling on about?
The last two posts in this series, based on a recent paper by Ted Nield and Iain Stewart, addressed the issues of why should scientists bother communicating, and what do people in general already know about science, and geoscience in particular. Oddly, these are the most fundamental questions when it comes to science communication, but often can be the most difficult to answer. They either require ...[Read More]

Friday Photo (57): Active Geology – Sinking Buildings from Ancient Greece
These foundations were once part of a building in ancient Greece. Over thousands of years, active faults have lowered the land and the foundations have sunk below sea level. Geology can have a big impact on relatively short timescales. (c) Geology for Global Development

In the News – November 2012
GfGD’s Director, Joel Gill, shares some of the things that have caught his eye in the news recently: Natural Disaters: The past couple of weeks have seen a significant number of natural disasters, from earthquakes in Guatemala and Myanmar (Burma) to hurricanes in the Atlantic – impacting developing nations such as Haiti, and a landslide dam break in Indonesia. The earthquake in Guatemala tri ...[Read More]
