Field work & Expeditions

The specificity of many of our research questions demands highly targeted and cleanly sampled rock specimens, as well as a thorough understanding of these samples in the context of stratigraphy and regional geology. With extensive experience in the field we organize and conduct expeditions in order to obtain exquisitely preserved and rare sample material. On this page we try to offer a photographic glimpse of some field sites that we have studied and sampled more recently. A more complete list of field expeditions can be found in Hallmann's cv.

Along the bank of the Belaya River, eastern Siberia.

Gornostakh antecline

Meso- to Neoproterozoic sedimentary sequence in eastern Siberia, visited in 2014 with Vladimir Pavlov (RAS), Sergey Malyshev (St. Petersburg University), Eric Bellefroid (Yale) and Andrej Shatsillo (Schmidt Institute for Geophysics).

MacArthur basin

Within the framework of a collaborativ effort to obtain a greater understanding of Mesoproterozoic environments, Jochen Brocks (ANU), postdoc Benni Bruisten, Matt Schmitz (Uni Jena) and myself studied sediments of the MacArthur basin in outcrop and in core: summer 2015.

Pilbara Archean drilling

Funded by the Agouron Institute, we pioneered the use of ultra-clean (hydrocarbon-free) drilling to study the oldest biomarker traces of life on Earth.

Belcher Supergroup

Paleoproterozoic rocks on the Belcher Islands host some of the oldest cyanobacterial microfossils. Together with Dominic Papineau, Marilyn Fogel and Paul Strother we visited and remote field site.

Chuar Gp, Grand Canyon

Some of the best preserved early Neoproterozoic sediments are found within the Grand Canyon. This study site is the PhD focus of student Lennart van Maldegem and was visited after an arduous multi-day hike.
