The mafic–ultramafic complex of Sikhoran presents a long geological history, marked out by various magmatic, metamorphic and tectonic events. This history is much more complex than a simple ophiolite obduction over a continental margin. As early as

The ophiolitic massif of Kahnuj (600 km2) consists, from bottom to top, of layered gabbros, isotropic gabbros and ouralite gabbros, agmatites of dioritic to plagiogranitic composition, a sheeted dyke complex and lastly a basaltic pillow lava unit. Am

The Rhodope massif of Bulgaria and Greece is a complex of Mesozoic synmetamorphic nappes stacked in an Alpine active margin environment. A new analysis of the Triassic to Eocene history of the Vardar suture zone m Greece discloses its Cretaceous sett

The wavelet analysis of the magnetic reversal sequence since 160 Ma discloses abrupt discontinuities in the evolution of the reversal frequency. They correspond, with a mean 3 Ma delay, to major plate reorganisations as defined by the formation or de

Subsidence analysis is used here to get a better understanding of the Eo-Cimmerian continental accretion to Eurasia of a block (the Iran Block) of Gondwanian origin. The drift of the block from Gondwana to Eurasia is classically considered as a late

The Pangea configuration for the interval of Late Carboniferous to Early Jurassic is still debated: was it similar to the well known Wegenerian Pangea or did Gondwanaland move with respect to Laurussia along a major right-lateral lineament of several

Mylonitic gneisses of the Bulgarian and Greek Rhodope were deformed under medium pressure-type metamorphism. The kinematic information contained in these gneisses shows that shear-deformation occurred during development of a nappe complex. Lithologie

Using a recent step-by-step reconstruction of the Mesozoic Tethys Ocean and surrounding continents, we draw the topologic patterns which characterise the networks of plate boundaries for pre-Tethys, Tethys and post-Tethys times. We define an asymmetr

This paper describes the evolution of the former Tethys ocean in terms of successive positions of the involved plates, their boundaries, and the oceanic and continental elements they bore. Most of the past positions for the major continents are obtai
