Aymon Baud<\/h3>

From 1977 to 1983, Aymon Baud (Geological Museum) participated in excursions, field campaigns and research in Ladakh and Zanskar (North India). Initiator of the research group on the Himalayas of the Museum and the University of Lausanne, he organized with Professors A. Escher, H. Masson and A. Steck the first geo-traverse of Eastern Zanskar, Hemis-Padum, in 1979. In 1981, he organized an expedition with Prof. G. Masde (Grenoble) and Dr. E. Garzanti (Milan) to make detailed stratigraphic sections and tectonic observations in central Zanskar, N and E of the Spongtang ophiolite klippe. In 1983, invited by Prof. M. Gaetani (Milan), he participated in a SE-NW geotraverse from Darcha (l.ahul) to Thongde (Zanskar) via Sarchu, Phirtse-La and Phugtal.
As western Tibet was only opened to foreigners in 1985, he was the first western geologist to enter the Kaila region after A. Gansser in 1936 and to cross the Tibetan plateau from Toling on the Sutlej valley to Yarkand, north of the Kun-Lun range.
For the collection of samples on the classic sections of the Permian-Triassic boundary, he participated in 1987 in an IGCP field meeting at Sall Ranges (Pakistan) followed by a field campaign in Kashmir (India) with Prof. G.Gaetani, J. Marcoux and E.T. Tozer.
In October 1988, he organized with Professors H. Masson, G. St\u00e4mpfli and A. Steck the fourth Himalaya-Karakoram-Tibet workshop in Lausanne. Steck the fourth Himalaya-Karakoram-Tibet workshop in Lausanne and was the editor of the conference proceedings published in Eclogae Geol. Helv. vol. 82.2 (1989).<\/p>

The main results obtained in collaboration with the above mentioned teams can be summarized as follows:<\/p>

  1. The discovery and definition of a large-scale vergent nappe structure in the Zanskars sedimentary belt (Tethys Himalaya). Despite strong opposition and controversy about the nappe theory by native-minded geologists, the nappe structure has recently been confirmed by detailed fieldwork and mapping.<\/li>
  2. A geological profile through East Zanskar from Hemis to Padum.<\/li>
  3. Detailed stratigraphic sections of the late Cretaceous and early Tertiary sediments of central Zanskar with geodynamic interpretation of the sedimentary record of the northward flight to India.<\/li>
  4. New observations in the Kailas region and along the Sutlej-Yarkand geotraverse.<\/li>
  5. Permian-Triassic isotope stratigraphy in the Salt Ranges and Kashmir.<\/li>
  6. A new geodynamic interpretation and chronology of Late Paleozoic rifting.<\/li><\/ol>
