Abstract:
Text S1 describes the analytical methods used in this study. Figure S1 is the X-ray mappings of garnets from the pelitic migmatites. Table S1 is the chemical compositions of garnet from the studied pelitic migmatites. Table S2 is representative chemical compositions of other minerals from the pelitic migmatites. Table S3 shows the whole rock Sr–Nd isotopes and major element compositions of the studied pelitic migmatite, the Late Cretaceous arc magmatic rocks and Neo-Tethyan ophiolites. Table S4 is zircon U–Pb dating and trace element data. Table S5 shows the zircon Lu–Hf and oxygen isotopic data.The block structure of the Earth crust and tectonic zones are displayed at the dynamic seismic section in the amplitudes of the scattered waves. Tectonic zones are identified with thrusts.<br>The effective density model of the crust was created at the base on the complex interpretation of seismic and gravity data.<br>Revealed tectonic elements of the Earth crust can be use for prognosis of oil perspective areas.<br>

The tectono-sedimentary analysis uses 3D seismic data to study dynamic controls of synsedimentary tectonics on sedimentation evolution.It aims to construct the relationship between tectonics and sedimentation.Compared with tectonostratigraphy,the tectono-sedimentary analysis emphasizes application of 3D seismic technique,and tectonic dynamic controls on both sedimentary processes and sedimentary filling.This study provides new thoughts and developments of the tectono-sedimentary analysis in the following aspects: 1) tectonic analysis;2) tectonic controls on sedimentary processes;3) response relationship between tectonics and sedimentary filling.The analysis of growth strata,grain size and 3D seismic technique are the three key methods used for the tectono-sedimentary analysis,which will have further application and deepening in the complex research of tectonics processes and sedimentary products in future.
