摘要
Based on regional seismic profiles,core and drill data of well in Tangguzibas Depression, Tarim Basin, the authors research the three-layer configuration of two unconformities, the one occurred between Early Silurian to Late Ordovician (S/O3,T70 seismic reflection horizon), the others emerged between Late Devonian to Silurian (D3d/S,T60 seismic reflection horizon). The structure deformation underlying unconformities, the distribution of configuration type of unconformities, the compositions and provenance of elementary sediment gravels overlying unconformities have been analyzed.
