Research interest and ongoing projects


1. Amalgamation and dispersal of Rodinia and formation of Gondwana, as exemplified by the Pan-African mobile belts of southern Africa,

    Madagascar and Sri Lanka

Specific projects include:

- Zircon geochronology and tectonic evolution of high-grade rocks in the Mozambique belt of eastern and southern Tanzania (in cooperation with S. Muhongo,


- Zircon geochronology and tectonic evolution of high-grade terrains in Madagascar (in cooperation with B.F. Windley, Leicester, U.K., A. Collins,

   Adelaide, Australia, T. Raza­kamanana, Toliara, Madagascar, and E. Hegner, Munich, Germany).

- Zircon geochronology and tectonic evolution of the Basement Complex in Sri Lanka (in cooperation with W. Kehelpannala, Institute of Fundamental

   Studies, Kandy, B. Prame, Geological Survey Dept., Colombo, and E. Hegner, Munich)

- Evolution of the Zambezi belt in northern Zimbabwe (in cooperation with C.W. Passchier, Mainz, and P. Dirks, Witwatersrand University, Johannesburg,

   South Africa).

- Timing of granitoid magmatism in the Damara and Kaoko belts of Namibia (in cooperation with C.W. Passchier, Mainz, and K.-H. Hofmann, Windhoek,



2. Lithospheric evolution of Eastern Gondwana from Interdisciplinary Deep Surveys (LEGENDS)

This is an international initiative, included in the International Lithosphere Program (ILP). It is concerned with the crustal structure of the various

crustal fragments that once made up the eastern part of Gondwana (East Africa, Madagascar, Sri Lanka, southern India, East Antarctica, Western

Australia). A north-south seismic survey is planned across southern India and Sri Lanka in 2004 and 2005, and workshops were held in India in

2003 and 2004. Symposia were organized at the joint EUG-EGS-AGU meeting in Nice in 2003 and at the first meeting of the Asia-Oceania Geoscience

Society (AOGS) in Singapore in 2004. Work by international groups from the US, Germany, Australia and Japan in cooperation with scientists

from India and Sri Lanka is now in progress.


3. Earth Accretionary Systems in Space and Time (ERAS)

This is an international multidisciplinary initiative, submitted to the International Lithosphere Program (ILP) by P.A. Cawood (Perth) and A. Kröner

(Mainz). It is specifically concerned with the recognition and evolution of pre-Mesozoic accretionary orogens and comparison with ongoing accretion

in the West Pacific, Alaska and the Caribbean, because the processes responsible for cratonization and incorporation of accretionary orogens

into continental nuclei and the mechanisms of formation of ancient accretionary orogens are poorly understood.

International workshops and conference sessions have so far been held at Geoscience Australia in Adelaide in 2003, a field workshop in Taiwan

in May 2004, and the first meeting of the Asia-Oceania Geoscience Society (AOGS) in Singapore in 2004. A special session will be held at the

GSA Annual Meeting in Salt Lake City in 2005.


4. Archaean crustal evolution

Specific projects include:

- Timing of granitoid magmatism and high-grade metamorphism in the Limpopo belt of southern Africa (in cooperation with G. Brandl, Council of

   Geoscience, Pietersburg, South Africa, and T. Blenkinsop, University of Queensland, Townsville, Australia).

- Timing of felsic magmatism and tectonics of the southwestern Barberton belt, South Africa (in cooperation with M. van Kranendonk,

   Geological Survey of Western Australia, Perth, Australia).

- Timing of granitoid magmatism and greenstone belt formation in the northeastern Kaapvaal craton, South Africa (in cooperation with G. Brandl, Council

   for Geoscience, Pietersburg, South Africa).

- Evolution of the late Archaean granulite belts of northern China (in cooperation with P.J. O'Brien, Potsdam University, C.W. Passchier, Mainz, S.W.

  Liu, Peking University, Beijing, G.C. Zhao and M. Sun, Hong Kong University and S. Wilde, Curtin University, Perth, Australia).


5. Evolution of the Palaeo- to Mesoproterozoic Epupa Complex of northwestern Namibia

This is an ongoing collaboration with the Geological Survey of Namibia and investigates granitoid gneisses and migmatites of the predominantly

Palaeoproterozoic Epupa Complex and structural overprinting during the formation of the Pan-African Kaoko belt. This is a contribution to a new

IGCP-Project on Palaeoproterotoic crustal evolution.


6. Tectonic evolution of the Central Asian Orogenic Belt

    Also part of ERAS (see above) and a contribution to IGCP-Project 480. This project aims at reconstructing the accretionary   

    history of one of the largest

    orogenic belts in  the world and involves fieldwork in Mongolia, southern Siberia, Kazakhstan and China. Specific projects    


- Ophiolites, arc terrains and microcontinents in Tuva and southern Siberia (in cooperation with J. Pfänder, Freiberg; W. Todt, Max-Planck-Institut für

   Chemie, Mainz; A. Kotov, I. Kosakov, V. Kovach and E.B. Salnikova, Institute of Precambrian Geology and Geochronology, Russian Academy of Sciences,

   St. Petersburg, Russia; E. Khain and V. Kuzmichev, Institute of Geology, Academy of Sciences, Moscow, Russia; E. Sklyarov and D. Gladkochub,

   Institute of the Earth´s Crust, Siberian Branch, Russian Academy of Sciences, Irkutsk, Russia; V.I. Lebedev, Tuvinian Institute for the Exploration of Natural

   Resources, Russian Academy of Sciences, Kyzyl, Tuva Autonomous Republic, Russia).

- Terrane accretion and tectonic evolution of Mongolia and northern China (in cooperation with B.F. Windley, University of Leicester, U.K., G. Badarch

  and O. Tomurtogoo, Institute of Geology and Mineral Resources, Mongolian Academy of Sciences, Ulanbaatar, Mongolia; E. Hegner and J. Tait, University

  of Munich, Germany; Liu Dunyi, Chinese Academy of Geological Sciences, Beijing, China; C. Buchan, Curtin University of Technology, Perth,

   Australia, M.T.D. Wingate, University of Western Australia, Perth, Australia).


7. Tectonic evolution of central and eastern Cuba

    (Havana) and scientists of the

    University of Moa tries to identify terranes in central and eastern Cuba and reconstruct their histories through structural work and zircon dating.


8. Micro-geochronological investigation of the timing of high-grade metamor­phism (jointly with A. Möller and P.J. O'Brien, Potsdam University, Germany)

     Emphasis is on:

   U-Pb isotopic systematics in UHT granulites from Enderby Land, Antarctica (in cooperation with S. Harley, Edinburgh 

   University, U.K.), UHT

   granulites from Namaqualand,

   South Africa (in cooperation with D. Waters, Oxford University, U.K.), and UHT granulites from southern Norway (in

   cooperation with B. Bingen, Trondheim,

   Norway, and J. Schumacher, Bristol, U.K.).
