Time for Fieldwork!

Thuesday will be the day I head due South to France. Starting October 1st I will be doing a little bit of mapping, measuring sections and taking plenty of samples for my Diplom thesis. The long-term weather forecasts look promising and with some luck I will be enjoying two weeks of perfect outdoor weather in the Alsatian Jura in the eastern-most part of France. I will be delving into the realm of shallow-marine carbonates, in particular oolites and oncolites. Internet access will be severely limited, in contrast to the last time I was on fieldwork. There should be enough material to make a few nice posts about fieldwork, carbonate sedimentology or karstification, I hope. It will be quiet here till mid-October.

The Lost Geologist interviewed on the Reef Tank

As I announced a few days earlier I have been sent some Q&A by Ava from the Reef Tank. The resulting interview on my own activities and their connection to marine geology is now up and available on their site. Here is a link directly to their blog. You can find me right on top at the moment. I hope you will find it interesting to read and I would welcome any feedback and so, I am sure, would Ava.

Upcoming interview on The Reef Tank

I've been asked by Ava from The Reef Tank if I would be willing to answer a few question about marine geology and my connection to it. It seems to be a very interesting site not only for aquarist but as well for those interested in reefs and the marine. Currently they are trying to build a new section on marine geology. So I gladly answered the short Q&A. The interview will most likely be published within the next few days on their site. I'm curious about the responds.

GPS - which one do you recommend?

I am pondering for some time now to get my own GPS device. For the upcoming field work (starting Sept. 29th) I will definitly need one, and no one seems to be able to lend me one. Our 10 or so university GPS are all broken. What GPS would you recommend for geological field work and mapping? I figure I need one that is quite accurate even under light tree cover, and also one that is able to display different projections, like UTM, Gauss-Kr├╝ger and other widely used methods. Do they still use Lambert in France? Most of my work I do in Europe - Germany, France and Switzerland and other central European states.

What do you think about the Garmin Colorado 300, the GPS 60 or the GPSmap 60 series? Price is really an issue for me.

8th Freiberg Short Course: Metallogeny and Exploration of Uranium Deposits

If you are interested in Uranium, its metallogeny and exploration, then I can recommend this years 8th Freiberg Short Course on Economic Geology at the Technical University of Freiberg, Germany. The almost one week long course will be presented by Professor Michel Cuney and others. All relevant kinds of Uranium deposits will be discussed and presented, including a field trip to the Uranium Ore collection of the WISMUT AG in Aue, the site of the former Uranium mining operation in communist times. One of the local organisers and presenters will be Dr. Thomas Seifert, an able and friendly mineral deposits expert of the Freiberg University whom I remember from various classes that I listened to in my Freiberg time. The course will be held from December 7th-12th in Freiberg.

Freiberg is not so far, perhaps 3 hours by train. If I will attend the course myself is still unclear, as I will be in the middle of my diploma thesis in december and probably stuck in a big pile of work.

Congress season

UPDATE: Unfortunately I got a very bad throat infection, high fever and lymph nodes as big as golf balls and hard as granite. My doctor ordered me to stay at home. Such a big disappointment! I was looking forward to meeting a lot of interesting people...

It has been going around in the Geoblogosphere that congress season has begun. I will be using the opportunity of having a lot of free time to attend the The 87th Meeting of the German Mineralogical Association at the Martin-Luther-University of Halle-Wittenberg. The meeting from the 13th till 16th of september will be covering a wide range of mineralogical and geological issues, also including archeology. My personal main interest will of course be to attend the symposia on mineral deposits and exploration in which will be presented a number of, I hope interesting, topics of mineral exploration in Germany. The most recent programm can be downloaded here.

Finally my diploma mapping project and report are completely off my desk! Monday I handed in the report at the examination office and today I gave a copy of it, and the map, to the two supervisors. Whatever comes now - it's out of my hands and I can't change it. And that's good! No more worries! I hope to have the results and grade within a few weeks, before I go to field work on my diploma thesis in France. I hope to also find a bit more time for blogging in september, now that my desk is empty again.

Gastropod fossils from the Hauptrogenstein

In my previous post I promised Aydin to post a few fotos of gastropod fossils that I came across during my mapping project. So follow-up on my promise here are four examples of fossil snails that one may come across in the oolithic Hauptrogenstein. My palaeontology isn't so great, and this was a mapping aimed at lime production, so we didn't bother so much about what these are exactly. If you can share some clues, feel free to contribute.

Sample from the Mumienbank, the top bed of the Middle Hauptrogenstein.
Oncoid with a gastropod nucleus. Probably a nerinea.

Detail from a polished slap of the Middle Hauptrogenstein. Somewhere from the "cross-stratified, oolithic complex" or coral-bearing Hauptrogenstein. Shells are 3 to 4 mm in size. Unidentified.

Gastropod sample from the coral-bearing Hauptrogenstein in close association with abundant coral debris (not recognisable in foto). A nerinean?

Wonderful 3D preservation of an archaeogastropoda(?) in close association with well-preserved, probably in-situ occurence, of branching corals (see below).

Branching-coral associated with the above mentioned gastropod fossil. Possibly encrusted with coraline algae?
