Where on Google Earth #207

Quite exactly half a year after my last WoGE win, I finally managed to find one again: in the last WoGE, Simon (hosted by Jeromes Blog) has shown the mountain Tronfjell, a nice gabbro intrusion in the Norwegian Caledonides. I'd like to present a rather younger feature:

Now translated: nice fold in southern Bavaria

This is just a pointer to an old post about a nice fold which I finally managed to translate. Follow this link or click on the image to find out more…

The case of the Ark and the missing dinosaurs

…has now been solved: (By Bizarro; found at Pharyngula the other day.) I'm quite happy that I didn't yet have to discuss with students the creationst crap the cartoon makes fun of.

First results of the geoblog survey 2009

I've waited so long for this, and now I've almost missed it: there are some first results from the geoblog survey 2009. Lutz Geißler presents a summary on (and a shorter German version on Also, there's going to be a publication about it in a not-yet-known journal. It's interesting (similar to the first […]

“Modern art” – hydrogeology

Grundwasserkarte von Bayern 1:25000, Blatt 6532 Nürnberg (1970).

Quite some time ago, I posted a colourful specimen of modern art and asked whether someone could tell what it is. One or two people seemed to like it, but couldn't add anything to my suggestion of the “Purple Woman Holding a Large Fish”. So now the picture in its complete context:

The Geologist and the Engineer, in the year 1928

Sometimes, leafing through old books yields little gems. The hydraulic processes of groundwater in nature cause great difficulties for calculations. To date, the geologist usually tends to rely on imagination [impression? understanding? concept? How the hell do you translate „Anschauung“?] only, and to disregard calculations completely. The mathematically trained engineer, on the other hand, often […]

Where on Google Earth #178

Dominion on her/his blog “The Couloir Times” has shown a part of the Blue Ridge Mountains where she/he grew up as WoGE #177. Just in time before Christmas, I'd like to present the new snowy/icy WoGE #178:

Practical courses for students of secondary school

Logo Forschungs-Bildungs-Kooperation Cottbus (FBK)

This month's Accretionary Wedge (hosted by Magma Cum Laude) is about earth science outreach, so I'd like to write a bit about the practical courses our university (BTU – Brandenburg University of Technology at Cottbus) provides for secondary school students in 11th and 12th grade. Our department (Environmental Geology) offers such practicals since 2007, but […]

Reminder: Take the geoblog survey

The new geoblog survey is online this month. This aims at getting a better picture of the geoblogosphere, and to find out what's good, what's bad, what's missing. However, participitation has been low yet. So if you own a geoscience-oriented blog, take this short survey! The survey is open until 1st November.

Where on Google Earth #174

David of Cryology and Co. has pulled us firmly into the Quaternary with the climate sequence from the Lac du Bouchet (some additional info about is in David's follow-up post). Here's my new WoGE picture. I hope to attract some new players (or reactivate the old ones), so I choose something not too difficult.

Where on Google Earth #172

Again, Péter's WoGE took quite some time to solve. (Or was just nobody interested?) He also suggested another twist to the game: the location should be connected to the previous one by some common concept, or “keyword”. His keyword was “type locality” – of komatiite, as it turned out. This prevented some of my nastier […]

Modern art quiz

I've stumbled across this nice piece of modern, abstract art: A purple woman with violet hair, holding a large fish in front of her body? Offer your explanations and interpretations!

Glacial deposits – lost in translation

I'm about to write some posts about maps I rather often use and realised that I'm not always quite sure about translations for various glaciation-related terms. (Pleistocene glacial sediments make up most of the geology in Brandenburg.) Most information I have found on the net focuses on valley glaciers and their landforms, less on the […]

Geological Time-Arm

[After switching to multilingual blogging, I have merged this english translation with the original article.]

Maps in the GDR – objects of state paranoia

When working on the local geology, I'm constantly reminded that in the former German Democratic Republic, topographic and geological maps were classified material. Most of the Lithofacies Map of the Quaternary 1:50000 (LKQ50) and the Hydrogeological Map 1:50000 (HK50) were ranked confidental („VD – Vertrauliche Dienstsache“, literally “confidential offical matter”), the rest was even secret […]

Geological history and structure of Europe

The Geochemical Atlas of Europe contains a nice short overview of the continent's geological and tectonic framework (PDF) and subsequent Tertiary and Quaternary landscape evolution (PDF). For more information on the structure, there's a slightly more detailed variant of the map with explanations from Christian Röhr's Upper Rhine Graben site (sorry, German only) and the […]

Visited countries meme

Again, I'm a bit late to the party: there's a meme going around about which countries of the world (and states of the USA) one has seen. So far,  NOLÖGIC, Looking for Detachment, Ethical Palaeontologist, Clastic Detritus, Highly Allochthonous, ReBecca's Blog, Hypo-theses, Geo­Christian, Mountain Cat Geology and Lost Geologist have posted their maps in English, and GeoBerg and Amphibol […]

Fold at Riedberg Pass in the Allgäu, south Bavaria

At the Riedberg Pass road near Obermaiselstein in the Allgäu (South Bavaria, Germany), a recumbent fold in the Flysch is not only nicely exposed, but also easily accesible – right at the roadside, including a (small and not “offical”) parking space. (A detailed location description is in section “Getting there” below.) Sadly, last summer I […]

Geologist's 100 things meme

Via the Lost Geologist I came across this 100 things meme – what have I done or seen? It was started by Geotripper; check the comments there for other people's lists. I am rather late to this, yet at the end of the year, it's a nice opportunity to look back.

Rocks of the “Early Anthropocene”

“Aqueduct marble” (travertine) from Cologne, diameter ≈25cm. Photo taken at the Geological Collection of the BGR, Berlin.

Today I visited the Federal Institute for Gesciences and Natural Resources (BGR) roughly the German analog of the USGS, for a talk about the OneGeology project. Sadly, this was cancelled on short notice, but as a substitute, they offered a tour of their Geological Collection. (Thanks to Dr. Ehling.) Besides shelves and cabinets with several […]
