Location & approach

By car

The campus of the Technical University of Dortmund is located near the freeway junction Dortmund West, where the Sauerland line A45 crosses the Ruhr expressway B1/A40. The Dortmund-Eichlinghofen exit on the A45 leads to the South Campus, the Dortmund-Dorstfeld exit on the A40 leads to the North Campus. The university is signposted at both exits.

By bus and train

The "Dortmund Universität" S-Bahn station is located directly on the North Campus. From there, the S-Bahn line S1 runs every 20 or 30 minutes to Dortmund main station and in the opposite direction to Düsseldorf main station via Bochum, Essen and Duisburg. In addition, the university can be reached by bus lines 445, 447 and 462. Timetable information can be found on the homepage of the Rhine-Ruhr transport association, and DSW21 also offer an interactive route network map.

The H-Bahn

One of the landmarks of the TU Dortmund is the H-Bahn. Line 1 runs every 10 minutes between Dortmund Eichlinghofen and the Technology Center via Campus South and Dortmund University S, while Line 2 commutes every 5 minutes between Campus North and Campus South. It covers this distance in two minutes.

By plane

From Dortmund Airport, it takes just over 20 minutes to get to Dortmund Central Station by AirportExpress and from there to the university by S-Bahn. A wider range of international flight connections is offered by Düsseldorf Airport, about 60 kilometers away, which can be reached directly by S-Bahn from the university's train station.

Plan of site & interactive map

The facilities of TU Dortmund University are located on two campuses, the larger North Campus and the smaller South Campus. In addition, some university facilities are located in the adjacent Dortmund Technology Park as well as in the city center and the wider urban area.

Trace of Stones — Determining the Age of Rocks with Radionuclides

Determining the age of material over geological timescales is a challenge, which can be met by the utilization of radionuclides.

Combining isotopes with different half lifes and different chronometric methods, allows for an accurate dating of samples from Hadean to the present. In addition, the utilization of crystal damage, due to nuclear fission provides insight into the thermal history of rocks, which allows for conclusions on the onset of uplifts of entire mountain ranges. This talk will discuss some of the most common dating techniques and exemplarily highlight their applications.
