Radiogenic & non-traditional stable isotopes: Institute for Planetology (IfP); University of Münster, Münster, Germany:
The Analytical Planetology Group of IfP, led by Thorsten Kleine, explores the origin and evolution of planets in the solar system by investigating the petrology, chemical and isotopic composition of meteorites and lunar, Martian and terrestrial samples. We use a wide range of research methods, including fieldwork, chemical microanalyses and isotopic techniques. Furthermore, with more than 3500 different meteorite samples the IfP hosts one of the largest meteorite collections worldwide.
Isotope Geochemistry and Cosmochemistry research utilises small variations in the isotopic compositions to address four main areas of research:
- Chronology of the early Solar System
- Accretion and differentiation of asteroids and terrestrial planets
- Origin and nature of the building blocks of the planets
- Late accretion and the origin of volatiles in the terrestrial planets
The specific facilities comprise ultra-clean laboratory for the preparation of extraterrestrial (ET) samples, a NeptunePlus MC-ICPMS, and access to sample preparation laboratories (digestion lab, mineral separation, heavy liquids) and geochemical support (ICP-MS, SEM, EMP). To minimize any risk of terrestrial contamination laminar flow hoods are exclusively used for the preparation of ET materials. The IfP laboratory routinely offers the following techniques: Short-lived isotopes: Hf-W, Pd-Ag, Mn-Cr; long- lived isotopes: Lu-Hf, Sm-Nd, Re-Os; stable isotopes (double spike): Cr, Ge, Mo, Ru, W; mass-independent isotope anomalies: Cr, Ti, Mo, Ru, Pt; highly siderophile element concentrations by isotope dilution.
