Friday Photo (56): Photos from Industry – Copper Deposits in Fault Zones

The deposits on the surface of this sandstone are a distinctive shade of green – indicative of copper. Copper is mobilised and concentrated along fault zones. If you have any photos from time spent working in industry, that do not breach company copyright regulations, then please get in touch and we will publish them on our blog!

Chilean volcanoes: shaken, but not always stirred?

Normally, September is not people’s favorite month as it goes with the end of the summer holidays, the beginning of the academic year and that of autumn. Not much to be happy about. Thankfully, space and planetary science is here to help you overcome this difficult period with lots of exciting events. Fly me to Bennu Asteroïds and comets were formed at the same time as the other planets, at the be ...[Read More]

Hurricane Sandy: A round up of the coverage from Haiti to New York

Hello, welcome, or welcome back! As of today ERE Matters, the blog of the Energy, Resources and Environment Division has been added to the EGU Blogs family :D (we thought about bringing cake, but that turned out to be a logistic distaster…) For some of you, we are the new kid on the block, but we actually have been around already for a few months! So please, join us for your regular dose of ...[Read More]


Geology Photo of the Week # 10 – Nov 4-10 – A Mysterious Monster!

I apologize for the delay posting this. I was in Washington DC earlier this week to take in a Supreme Court hearing that never actually happened due to Hurricane Sandy. My flight out was also delayed and thus many other things in my life are delayed right now including this post. This photo poses a bit of a conundrum…since I don’t have a clue what it is! I have an idea, but I’d l ...[Read More]

Water Series (2): Fluoride Contamination in Drinking Water

This week, as part of our ‘water series’ we will focus on fluoride contamination in drinking water. In some parts of the UK we add fluoride to our drinking water, because small amounts can help to protect your teeth. However, too much fluoride (>1.5mg/L) can lead to a serious medical condition called fluorosis, affecting the development of teeth and bones. This strong dosage dependency can lead ...[Read More]

Friday Photo (55): Photos from Industry – Man Operating Machinery at a Mine in China

Man Operating Machinery at a Mine in Anhui Province, China There are many large mining operations covering Anhui Province, China. They tend to have limited safety regulations. The mines can ruin the landscape, cause pollution and can be dangerous places for people to work. However, this primary industry is fuelling China’s rapid growth and development. Our Friday Photo series will be focused ...[Read More]

Water Series (1): The Quantity and Quality of Groundwater

The water available in or near your home can vary dramatically over short distances. In Manchester, there is a robust supply of fresh water from the Lake District, whereas in London (only 200 miles away) the water has passed through limestone, leaving it with a cloudy taste and causing limescale build-up. Signs up on the London underground at the moment are encouraging people to save water by taki ...[Read More]

Friday Photo (54) – Debris Flow Channel, Gansu Province, China

Southern Gansu Province, China: Poorly Maintained Debris Flow Channel This channel is designed to transport debris flow material away from the road, thus preventing a major road blockage. The poor design and maintenance of the channel, however, is resulting in material coming down the channel and then being pushed back on to the road. (c) Geology for Global Development, 2012


Geology Photo of the Week #9 – Oct 21-27

Changes in climate have a major impact on sediment dynamics in cold environments from high arctic/antarctic and subarctic/subantarctic to alpine and upland sites. Climate changes influence the nature and extent of glaciers, permafrost areas, ice sheets and the extent and intensity of glacial, peri-, pro- and paraglacial processes. In this context major foci of the workshop are related to: Observat ...[Read More]
