Beschreibung:
Seismic data from central Tibet have been combined to image the subsurface structure and understand the evolution of the collision of India and Eurasia. The 410- and 660-kilometer mantle discontinuities are sharply defined, implying a lack of a subducting slab beneath the plateau. The discontinuities appear slightly deeper beneath northern Tibet, implying that the average temperature of the mantle above the transition zone is about 300 degrees C hotter in the north than in the south. There is a prominent south-dipping converter in the uppermost mantle beneath northern Tibet that might represent the top of the Eurasian mantle lithosphere underthrusting the northern margin of the plateau.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Kind, R -- Yuan, X -- Saul, J -- Nelson, D -- Sobolev, S V -- Mechie, J -- Zhao, W -- Kosarev, G -- Ni, J -- Achauer, U -- Jiang, M -- New York, N.Y. -- Science. 2002 Nov 8;298(5596):1219-21.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉GeoForschungsZentrum Potsdam, Telegrafenberg, 14473 Potsdam, Germany. kind@gfz-potsdam.de〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/12424374" target="_blank"〉PubMed〈/a〉
