Scientist inclined to minerals, rocks and related objects

Active Research Interests:

- Mechanisms and kinetics of reaction rim growth
This series of projects comprises several experimental studies in the systems MgO(FeO)-SiO2, CaO-SiO2, Al2O3-SiO2, under dry and water-bearing conditions, leading to a number of publications starting from 2001. In a presently running study several dopants (Ni, Co, Mn, Ca, Zn) are introduced to orthopyroxene rims growing between olivine and quartz to explore their redistribution and kinetic fractionation in the reaction rims. Experiments are done with natural and synthetic reactants at high pressure and temperature, working with mineral powders, polished single crystals and silicate thin films. This research initiative initiated a number of PhD and PostDoc projects within the framework of the DFG Research Group 741, and is still open for new ideas. The experimental work is done in cooperation with GFZ Potsdam. Main research partners: Wilhelm Heinrich, Bernd Wunder, Monika Koch-Müller, Dan Harlov, Michael Wiedenbeck (GFZ Potsdam), Rainer Abart (University Vienna), Ralf Dohmen (University Bochum).

- Reactions between mafic minerals and silicious or alkaline melts
Reactions between olivine, orthopyroxene(s), spinel(s) and phonolite melt are studied in the Heldburg Phonolite, Thuringia, that is considered a natural experimental lab for the investigation of mantle metasomatism by alkaline fluids. In a PhD-project the experimental reaction between mafic minerals and alkaline as well as silicious melts is investigated under controlled conditions. Research partners: Wilhelm Heinrich, Bernd Wunder (GFZ Potsdam), Sanjay Pandey (New Dheli, India).

- Petrogenesis and crystallisation history of melilitites and nephelinites
I have recently come back to this research theme, built on an interest in chemical zoning and growth textures of spinels in these silicate-undersaturated rock suites. Cpx-melt thermobarometry is another interesting tool. There is a big potential in fluid inclusions and in combining petrogenetic informations from spinel/olivine/pyroxene zonations, fluid inclusions, and melt-mineral equilibria and disequilibria. Actual sample areas are in central and SW-Germany and in the Eger (Ohre) rift. Together with the Polish partners the study areas are to be expanded both in Poland and Germany. Research partners: Udo Neumann (University Tübingen), Lutz Hecht (Natural History Museum, Berlin), Jacek Puziewicz (University Wroclaw, Poland).

- Petrogenesis of highly differentiatiated alkaline rocks
Phonolites are the highly evolved products of the fractional crystallisation of mafic alkaline melts. However, there are phonolites and phonolites, not to speak of tephrites... or carbonatites... and very many details of their formation including e.g. polybaric fractionation and liquid exsolution are matters of debate. Recent field work took place at the Heldburg phonolite, Thuringia. For comparison, phonolites in SW Germany and on the Canary Islands are in the research focus as well. Research partners: Andreas Klügel, (University Bremen), Lutz Hecht (Natural History Museum, Berlin), Tibor Guzmics (University Budapest).

- Writing sand, its use and its distribution in time and space
To my best knowledge I was the first person to make writing (or blotting) sand a topic of mineralogical research. Blotting sand was the alternative to blotting paper for centuries. The remaining sand can still be found in manuscript archives. Together with my research friends I collected a lot of data from the city of Basel (Switzerland), SW Germany, and New England (USA). There are a lot of open questions, f.ex. who produced tons of sand containing crushed staurolite for decades in the early 19th century in southern Hesse and around, and why? And why was this sand bought and used as blotting sand? This is a topic only for candidates open for a sense of wonder. Research partners: Albert Spycher (Basel, Switzerland), Nick D'Errico (North Haven, USA; passed away in May 2012)

- Silicification/Opalization
Opal (precious and ordinary) occurs in altered volcanic rocks and purely sedimentary environments. Opal (in all its crystallographical and microstructural variants) comprises a metastable form of silica that is able to replace almost everything: wood, limestone, sandstone, bones, ... There are recipees to make artificial precious opal, but these use chemicals absent from natural systems. Big questions: How does precious opal form under natural conditions? Which mechanisms take place during the replacement of almost everything? Does the chemical nature of replacement fronts feed back into the nature of the replacing opal? This research is driven together with Moritz Liesegang (inhouse). Research partners: Jürgen Ganzel (Berlin-Zehlendorf), Chris Ballhaus (Bonn University).

- Reaction mechanisms of glass weathering, pattern formation, consequences
This research started with thrown away glass bottles from Australian opal fields, but the kind of glass alteration we look at (that creates iridescence) in the meantime also includes bottles and shards from the Atacama desert in Chile, from just behind the surf in Tenerife, and from the dish washer at home. Iridescent surface layers form by a self-organised mechanism that still awaits conclusive explanation. In natural weathering environments salinar soil fluids seem to play a role, and most of all the action of bacteria and possibly their deterioration products within nm-scaled layers between silica-dominated interfaces. A future topic! Research partners: Andreas Lüttge (Rice University, Houston, USA)

- Texture formation in oxide and silicate thin films
In a PhD guided by Susan Schorr and me we study texture formation in spinel and orthopyroxene thin films (hardly 1 µm thick) using micro- to nanoscale X-ray and electron beam ex-situ methods as well as in-situ synchroton observation in a reaction chamber. When everything is running the facilities should be useful for further investigations as long as there are new ideas. This is a joint project between FU Berlin and Helmholtz Center Berlin, including the Bessy beam line. This work is done together with Ralf Dohmen (Bochum).
