Facilities
The Geological Institute has a wide range of outstandingly equipped laboratories, with a 170 m2 huge laboratory for teaching purposes.
Impressions: Teaching Lab
The Teaching Laboratory provides laboratory space to accommodate approximately 20 students in order to enable instruction on laboratory and analytical methods, and to undertake a diverse array of practical assignments.
It features several robust, widely used analytical instruments relevant to a broad array of courses in surface earth processes such as basic inorganic and organic geochemical analysis of aqueous and solid samples as well as characterization of particulate grain sizes.
- Elemental analyzer (EA)
Determination of bulk elemental composition (C, H, N, S) of rock, sediment and soil samples - Gas Chromatograph/Mass Spectrometer system (GC)M
Molecular‐level analysis of complex mixtures of organic compounds in geological matrices (sedimentary rocks, sediments, soils, petroleum). - Ion Chromatograph (IC)
The measurement of major cations and anions (Ca2+, Mg2+, K+, NH4+, Na+, HCO3‐, SO42‐, Cl‐, F‐, NO3) - Gas generator system to support instruments and preparation
Gas supplies are needed for many of the instruments (high flow N2, high purity N2, clean air, H2) and some preparation steps - UV/Vis spectrophotometer (UV/Vis)
Quantification of pigments, proteins, dissolved organic matter - Picarro CRDS for oxygen and hydrogen isotopes in waters (CRDS)
Determination of water isotopes (d2H, d18O) that is used to investigate the hydrological cycle and its links to geological processes - Mastersizer 2000 grain size analyzer
Determination of the size distribution of particles, from natural sediment/soil to materials science
The instruments in our lab allow students to directly learn the principles of basic analyses which are standard methods applied in government agencies and applied research in private consulting companies. The technology is in each case well established, comprising a mainstay of fundamental and applied research for decades, and is likely to remain relevant for the foreseeable future.

The Rock Physics and Mechanics Laboratory (RPMLab) at ETH conducts research on the mechanical behavior and transport properties of Earth materials at conditions pertaining to the Earth’s crust and upper mantle. This is accomplished by means of experimental research coupled with microstructural studies of the micro-scale processes, and modelling of these processes. The RPMLab is working on a range of problems, including rock deformation, rock physics, elastic wave properties of rocks, volcano-tectonics, coupled thermo-hydro mechanical process in earth crust and deep reservoir characterisation.

The stable Isotope Laboratory is part of the Climate geology group. One focus of our research is the development of novel analytical techniques for the analysis of the isotopes of carbon, oxygen, hydrogen, nitrogen and sulfur.
Currently we are focusing on Carbonate clumped isotopes. In particular, we are we are improving the methodologies for the analysis of clumped isotopes in carbonates in order to reduce sample sizes and are applying this method to the reconstruction of past climate change, to diagenesis and low temperature hydrothermal systems. Furthermore we work on various projects involving oxygen isotopes in phosphates, sulfates, water and carbonates, sulfur isotopes in different sulfur phases, hydrogen isotopes in water and low molecular weight hydrocarbons, and carbon and nitrogen isotopes in organic substances.

In addition to the Climate Geology Stable Isotope Laboratory, the Surface Earth Evolution group focuses on high-precision triple- and clumped-isotope measurements of oxygen. We build new tools and develop new methods to extract and analyze oxygen isotopes from various mineral phases (silicates, sulfates, oxides), water, and O2 gas. We specifically aim to advance these measurements in four key ways: (i) improve user safety by circumventing the need for toxic fluorine gas, (ii) increase throughput by developing automated extraction lines, (iii) improve precision and (iv) reduce necessary sample sizes by optimizing extraction line design. These analyses are useful for paleohydrology and paleoclimate reconstructions, as well as for constraining modern biogeochemical cycles.
