Inside a fault

In September, Klaus and me lead a MSc student excursion to southwestern Germany. We not only went through the entire stratigraphy of that area (mainly Triassic and Jura), but also visited the salt mine in Stetten, quarries in Dotternhausen (opalinus clay, posidonia schist, Malm), the Kaiserstuhl carbonatite volcano complex and the Upper Rhine Graben area. One of my personal highlights was the Freudenstädter Graben, a small tectonic graben striking NW-SE, whose NE main fault is exposed in an old mine in Hallwangen. Continue reading “Inside a fault”

Geo-sites meme: 101 American Geo-Sites You’ve Gotta See

Callan Bentley from Mountain Beltway had the idea to list the 101 American Geo-Sites mentioned in Albert B. Dickas’ book and to mark those he has already visited. The whole thing became kind of popular in the geoblogosphere, and this KMZ by one of Callan’s readers allows to explore the 101 outcrops one definitely has to visit in the US. So now here’s my list, in bold the places I’ve visited (as you will see, there are far much still to be seen than I’ve already visited!):

  1. Wetumpka Crater, Alabama
  2. Exit Glacier, Alaska
  3. Antelope Canyon, Arizona
  4. Meteor Crater, Arizona
  5. Monument Valley, Arizona
  6. Prairie Creek Pipe, Arkansas
  7. Wallace Creek, California
  8. Racetrack Playa, California
  9. Devils Postpile, California
  10. Rancho La Brea, California Continue reading “Geo-sites meme: 101 American Geo-Sites You’ve Gotta See”

Paleoseismological trench at the Finale Emilia earthquake site

A paleoseismological trench has been opened at San Carlo – Sant’Agostino. At this place, liquefaction features and other environmental earthquake effects were recognized after the Finale Emilia earthquake of 2 May 2012, magnitude MW6.1. The trench reveals normal fault features close to the surface. Our colleague Alex Chatzipetros from Earthquake Geology of Greece posted a great article on the trench work and has all the interesting photos.

PostDoc research position on Tsunami deposits, EQ Geology, Tectonics (Mexico)

The Group on Active Tectonics (GAT) and the Environmental Geophysics University Laboratory (LUGA) at the National Autonomous University of Mexico (UNAM), Campus Morelia seeks applicants for a Postdoctoral Research position. The candidate will pursue fundamental and applied research into either a) active tectonics and/or b) tsunami deposits and paleoseismology with focus on the Mexican Subduction Zone. The candidate will be responsible for the development and execution of field and laboratory research, and to conduct studies on the geologic signature left by great earthquakes and their tsunamis. The fields of application include earthquake hazard, tsunami hazard and long-term earthquake record of this active margin.

Excursion and field work in Greece – landslides, rock falls, fault scarps

Since ten days I am in Greece now with a dozen of students. We started with an excursion in the western Peloponessus area and had a look at the regional tectonics, sedimentology (mainly Neogene Flysch units and young beach rocks), the large limestone horsts of Gavrovo and Ionian units, Ancient Olympia and recent mass movements. Then we began with field work for BSc, MSc and PhD theses. Continue reading “Excursion and field work in Greece – landslides, rock falls, fault scarps”

Take part in an experiment: Measuring tectonically offset features

Folks at Arizona State University and San Diego State University are conducting a study to test the repeatability, accuracy, and precision of lateral displacement measurements derived from high-resolution topographic Light Detection and Ranging (LiDAR) data. Please take a few minutes to participate! If you have any questions about the research or would like to use the materials as a classroom exercise, please feel free to email Barrett at jbsalisb@asu.edu.

Back from field work in Oman

Klaus, Ben, Sascha and me went to visit our colleague Gösta at the GUtech in the Sultanate of Oman. We did some fieldwork for our project which deals with coastal changes. Parts of the Omani coast subside, others appear to be stable or are even uplifted. This might be due to large scaled crustal movements (the Makran Subduction zone is nearby) and/or regional effects. We are trying to find good proxies for reconstructing the Holocene sealevel and climate changes. Additionally, we need to get a grip on the neotectonics that affect the coastal areas. Continue reading “Back from field work in Oman”

On the rocks – how to cool Whiskey adequately

Today’s post is about Whiskey. And Whisky. More precisely, about how to cool it adequately as a geoscientist. I received a great Christmas gift from Andreas – ice cubes made up of “Nordic Rocks”. The manufacturer promises a perfect way of cooling drinks by adding one to three pieces of 400 million year old swedish bedrock. No thinning of the drink, no pollution.
