GeoPicture of the week: Mind blowing Bismuth

This is Bismuth – it is a natural chemical element which chemically resembles arsenic and antimony. Elemental bismuth may occur naturally, but this form does not occur naturally – it was developed in a lab. Still, it’s just mind boggling how beautiful it is!

GeoPicture of the Week (2): Volcanic eruption seen from the space shuttle

In this incredible capture taken on 30 September 1994, we see a major eruption of Klyuchevskaya Sopka as seen by the astronauts aboard the Space Shuttle Endeavour. It is yet another testament of the immense power that volcanoes have, as the ash rose 60.000 feet into the air (almost 19.000 meters) and spread as far as 640 miles […]

GeoPicture of the week: British folds

There is some magnificent cliff walking on Cornwall in Great Britain, I’d really recommend it to everyone who’s even remotely interested in geology. This picture was taken in the Crackington Haven area; it;s like these Carboniferous rocks were tortured by the tectonic forces as the Rheic Ocean finally closed and Pangea was formed. Truly awesome!

GeoPicture of the Week (fossil): Palm blossom with 3 Diplomystus dentatus (fish)

The fossil was taken from the Green River formation, an Eocene geologic formation that records the sedimentation in several lakes along the present-day Green River in Colorado, Wyoming, and Utah. Lake sediments are among the best to preserve fossils and other significant geological information. The Eocene epoch lasted from 56 to 33.9 million years ago, […]

GeoPicture of the Week: Surfing on Lava. Literally

This is a lava wave. CJ Kale, an extreme nature photographer from the Big Island of Hawaii literally risked his life in order to take this magnificent shot. Here’s what he had to say about it: This is the first ever photo taken surf photography style with the lava down the wave. I entered the […]

GeoPicture of the day: Fossil dating and a creationism musm

While I don’t really like to mingle in the scientific debunking of creationism and all the related discussions, putting information like this on a plate in a so-called museum is offensive. It’s offensive, it’s spreading false information, and it’s discouraging visitors (most notably kids) from thinking logically and scientifically correct.

GeoPicture of the week: Tree fossil with opal growth rings

This is a part of an opalized tree, and the rings you see are actually tree rings; or at least they were. This is an very rare sample: opal can be fairly common in petrified wood, but this is a fire opal, which makes it so much more valuable. Fire opals are transparent to translucent […]

GeoPicture of the week: The Namib desert as seen from above

The Namib is a coastal desert in southern Africa, stretching along more than 2,000 kilometres (1,200 mi) along the Atlantic coasts of Angola, Namibia, and South Africa. The desert geology consists of sand seas near the coast, while gravel plains and scattered mountain outcrops occur further inland. The sand dunes, some of which are 300 metres […]

GeoPicture of the Week: 300 ft (100 m) high wall found in Bolivia with over 5000 dinosaur footprints, in over 462 discreet trails

This wonderful picture is so full of geology it makes my head spin. If you zoom in on the picture (higher resolution here) you’ll see the dinosaur footprints – there’s over 400 discreet trails. a huge number; the natural question after this, of course is how did they end up sideways ? This rock is […]

GeoPicutre of the Week: Fossilized crinoids

This picture of fossilized crinoids was taken at the Sternberg Museum of Natural History, in Hays, Kansas. Crinoids are marine animals that are still alive today, even though their ancestors emerged during the early Cambrian, some 540 million years ago. They are echinoderms, related to starfish and sea urchins. They feed by filtering small particles […]
