IGCP Project 559 - Seismic Images
Active collision zones
East European Craton – Southern margin – Stephenson
Transect across south-eastern Sarmatia, the southernmost East European Craton. The Transect crosses the Archaean-Palaeoproterozoic Ukrainian Shield, the Voronezh Massif and the intervening Late Palaeozoic Donbas Foldbelt and Dniepr-Donets Basin. Results image an inverted intracratonic rift basin and subjacent crust and upper mantle.
Indian sub-continent crustal structure, India
Summary of seismic tomography experiments in the Himalaya and Peninsular Shield regions of India. Seismic results in the Peninsular Shield area show internal structure of the three cratonic regions; Aravalli, Dharwar and Singhbhum, and the bounding Proterozoic rifts and mobile belts. Seismic results in the Himalaya region show structures formed during collision of India with Eurasia.
Western Alps Transect, Europe (I)
Transect across the European plate, from the preAlps to the west, across the Helvetic and Penninic nappes, the Valais and Insubric structures, the Briançonnais and Austroalpine terrains, the Ivrea Zone, the Piemont suture to the Southern Alpine area. Results show subduction of the European plate under the Adriatic lithosphere.
Western Alps Transect, Europe (II)
Transect across the European plate, showing results from the ECORS transect.
Western Alps Transect, Europe (III)
Transect across the European plate, showing details of part of the results from the ECORS-CROP transect.
Ionian Sea Transect, Mediterranean Sea
Transect across the Ionian Sea between Sicily and Turkey. Structures crossed include the western margin of the Hellenic Arc, the Pre-Apulian zone and the Kefallina transform fault. Results suggest the dominant tectonics were compressive deformation of the Mediterranean ridge and the extensional tectonics of the Aegean arc.
Tibetan Plateau Transect, northern India - Tibet or
Tibetan Plateau Transect, northern India - Tibet
Transect across the eastern part of Tibet crossing the Lhasa, Qiangtang and Songpan-Ganzi Terranes. The transect shows images of the crust and upper mantle beneath Tibet. Results provide information on the collision between India and Eurasia and that the Indian crust and mantle lithosphere was underthrusting the Lhasa terrane.
The SESI seismic reflection profile images the geometry of the pre-110 Ma basement units down the south-east coastline of South Island . It sheds light on the geometry of terrane boundaries preserved in approximately their pre-Cenozoic configurations.
SIGHT96 experiment crosses the central South Island of New Zealand. Transect aimed at understanding the crustal-upper mantle deformation that is occurring at a continental obliquely compressive plate boundary.
SIGHT98 is a follow-up to SIGHT96. It also is an experiment that crosses the central South Island of New Zealand. Transect aimed at understanding the crustal-upper mantle deformation that is occurring at a continental obliquely compressive plate boundary.
