Crustal structure and deformation of the SE Tibetan plateau revealed by receiver function data
We analyze a large amount of receiver function data recorded by regional seismic networks of the China Earthquake Administration to estimate crustal structure and deformation beneath the southeast margin of the Tibetan plateau and its surrounding areas. We develop a comprehensive analysis method that facilitates robust extraction of azimuthal seismic anisotropy from receiver function data. The ...
متن کاملGeochemical comparison between Archaean and Proterozoic orthogneisses from the Nagssugtoqidian orogen, West Greenland
In the Palaeoproterozoic Nagssugtoqidian orogen of West Greenland reworked Archaean and juvenile Proterozoic orthogneisses occur side by side and are difficult to differentiate in the field. Archaean gneisses have tonalitic to trondhjemitic compositions with relatively low Al2O3 and Sr, and may have been derived from magmas formed by melting of basaltic or amphibolitic rocks at moderate pressur...
متن کاملCrustal structure and apparent tectonic underplating from receiver function analysis in South Island, New Zealand
[1] We utilize seismic converted phases on more than 700 receiver functions calculated for 42 stations in the South Island, New Zealand, to infer crustal and uppermost mantle structure. We determine the crustal thickness from direct observations of conversion from the Moho interface and infer zone of the maximum thickness being located along the axis of the Southern Alps, just east from the Alp...
متن کاملPopulation structure of West Greenland narwhals
The hypothesis that different populations of narwhals in the West Greenland area exist has been tested by different biomarkers (metal and organochlorine concentrations, stable isotopes and DNA). Samples of muscle, liver, kidney, blubber and skin tissues of narwhals from West Greenland have been analysed for heavy metals, organochlorines, stable isotopes and DNA. The obtained results of metal co...
متن کاملCrustal Structure of the Tibetan Plateau and Its Surroundings from Receiver Function Studies
The Tibetan Plateau is the highest and largest plateau in the world, generated by the collision of India and Eurasia. Details of this continent-continent collision and the uplift mechanism of the plateau are still hotly debated. In this study, I collected a large amount of seismic waveform data recorded by more than 300 stations in Tibet and its northern neighbor Tien Shan. I processed the data...
