Brillouin-Interferometry

_Brillouin-Interferometry_

Knowledge of the elastic properties of geomaterials at high P-T conditions plays a central role in determining the composition of the Earth's interior. The Brillouin interferometer at the GFZ Helmholtz Centre for Geos…
Earth System Observatories (Regional Observatories)

Our observatories are a key instrument for a comprehensive understanding of the system Earth. The combination of monitoring programmes and observatories allows for an observation of the processes shaping the Earth system from a local to a global sca…
Electronic Laboratory for Geophysical Exploration Systems

The development of geophysical exploration systems with high resolution for underground applications and mobile operation on the surface implicate many interesting problems to be solved with electronics. That is, design and programming of radio-cont…
Experimental Rock Deformation Laboratory

For rock deformation experiments we handle different apparatuses, allowing to perform brittle (low temperature) tests on large rock samples (MTS servo-hydraulic press) and high temperature (ductile) experiments on small samples (Paterson-type gas de…
GFZ-Underground-Lab “Reiche Zeche” in Freiberg

The use of high-resolution geophysical exploration systems, developed by the HGZ Helmholtz Centre for Geosciences, for underground applications at tunneling and within boreholes requires a high demand due to safety and operational reliability. The G…
GONAF - Geophysical Observatory at The North Anatolian Fault

GONAF (Geophysical Observatory at the North Anatolian Fault) is a combined surface and downhole based observatory to measure tectonic deformation transients (seismic and aseismic) along the overdue Marmara segment of the North Anatolian Fault Zone (…
High P and T Synthesis Laboratory

For high-P/high-T experiments, we offer various kinds of piston-cylinder- and multi-anvil presses, which are utilized for conditions ranging from the crust to the uppermost lower mantle. In detail, the High P and T Synthesis Laboratory includes the …
ICDP International Continental Scientific Drilling Programme

The International Continental Scientific Drilling Program (ICDP) is a multinational program to further and fund geosciences in the field of Continental Scientific Drilling. Scientific drilling is a critical tool in understanding of Earth processes a…
KTB - German Continental Scientific Deep Drilling Programme In Windischeschenbach, Germany (Kontinentale Tiefbohrung)

The Continental Deep Drilling Program of Germany (in German: Kontinentales Tiefbohrprogramm der Bundesrepublik Deutschland, abbreviated as KTB) was a scientific drilling project near the town of Windischeschenbach, Bavaria. The KTB Depth Laboratory …
OSG ICDP | Operational Support Group of the International Continental Scientific Drilling Program

The Operational Support Group of the International Continental Scientific Drilling Program, ICDP, situated at GFZ, provides downhole logging services and access to utilize the ICDP instrument pool for PIs of successful ICDP proposals. ICDP is a prop…
Piston Cylinder / Multi Anvil Press

The static 1000 t laboratory press of Max Voggenreiter GmbH can be operated either with a Walker module as a multi anvil press or via a second hydraulic cylinder with a piston cylinder module (diameter 12.7 mm).
Piston Cylinder Press

To investigate the pressure/temperature regime of the Earth´s crust and shallow parts of the upper mantle, at the GFZ three piston cylinder presses are installed and run. Two of the three presses are non-endloaded piston cylinder apparatus ("Johanne…
Pore and Fracture Space Laboratory

For characterization of pores and fractures within rocks the laboratory is equipped with an X-Ray computer tomography system (Nanotom CT), He-gas pycnometer (AccuPyc), Hg porosimeter (2000 WS), and a gas adsorption porosimeter (TS Surfer). For damag…
Rotating Multi-Anvil Press

A Rotating Multi-Anvil Press constructed by Max Voggenreiter GmbH is installed in the high-pressure hall of the GFZ. The apparatus consists of an 800 tons hydraulic press and a Walker-type multi-anvil module. The whole apparatus is rotatable by 360°…
The KTB Deep Crustal Lab

During the KTB project (1987-1995) two deep boreholes were drilled, the so-called pilot hole (KTB-VB, 4 km) and the ultra deep main hole (KTB-HB, 9.1 km). Both wells are nearly completely cased. The VB is accessible to nearly bottom hole. At KTB is …
X-Ray Diffraction Methods

For X-ray diffraction characterisation of solid materials, we hold two STOE STADI-P powder-X-ray diffractometers. Collected pattern are processed with the GSAS-software for Rietveld refinement.

For the crystallographic orientation of single cryst…
mDIS – mobile Drilling Information System

The mobile Drilling Information System (mDIS) is a database management application developed and provided by the International Continental Scientific Drilling Program (ICDP) for capturing and curating metadata on geological cores and samples, drilli…
