Structure and evolution of the Himalaya–Tibet orogenic belt
The 1981 French–Chinese expedition to Tibet focused on the Lhasa block, extending earlier coverage 400 km north of the Tsangpo suture. The Lhasa block stood between 10 and 15° N latitude over most ofExpand

Tethyan margins in space and time
Abstract Rifting processes, leading to sea-floor spreading, are characterized by a sequence of events: transtensive phase of extension with syn-rift volcanism; simple shear extension accompanied byExpand

The Xigaze ophiolite (Tibet): a peculiar oceanic lithosphere
The Xigaze ophiolite which outcrops along the Yarlung Zangbo river, southern Tibet, locally displays a complete ophiolitic sequence from marine sedimentary cover over basaltic volcanics to the north,Expand

Tectonic environment and geodynamic significance of the Neo-Cimmerian Donqiao ophiolite, Bangong-Nujiang suture zone, Tibet
The Bangong-Nujiang suture zone is underlain by a discontinuous and roughly EW ophiolite belt. Around Donqiao–Gyanco, ophiolitic and metasedimentary Palaeozoic series form nappes thrusted overExpand

New constraints on the End-Triassic (Upper Norian–Rhaetian) magnetostratigraphy
Abstract The end-Triassic was marked by one of the five important Phanerozoic global mass extinctions. The construction of a detailed magnetic polarity time scale for this period, that wouldExpand

Integrated Upper Carnian to Lower Norian biochronology and implications for the Upper Triassic magnetic polarity time scale
Abstract We summarize the ammonoid, conodont and halobiid biochronology of the Upper Carnian to Lower Norian, based on a discussion of data in the Alps, Sicily, Balkans, Turkey, Himalayas and Timor.Expand

Calcimicrobial cap rocks from the basal Triassic units : western Taurus occurrences (SW Turkey)
Abstract A post-extinction calcimicrobial cap rock occurs above the giant Permian skeletal carbonate platform exposed in the western Taurus Mountains (southern Turkey). It was formed during the mainExpand

Magnetostratigraphy of the Late Triassic Bolücektasi Tepe section (southwestern Turkey): implications for changes in magnetic reversal frequency
Abstract A magnetostratigraphic study of light-pink to white pelagic limestones from the Bolucektasi Tepe section (southwestern Turkey) provides a magnetic polarity sequence well calibrated with theExpand

The Tibetan side of the India–Eurasia collision
Results are reported from the 1980 joint French–Chinese field expedition in Tibet. The area covered was from the High Himalaya in the south, to the region of Nagqu ∼250 km north of Yangbajain.Expand
