Late Neoproterozoic intracontinental rifting of the Tarim carton, NW China: An integrated geochemical, geochronological and Sr–Nd–Hf isotopic study of siliciclastic rocks and basalts from deep drilling cores

Late Neoproterozoic extensive rifting in Tarim has been intensely debated regarding an intracontinental or a back-arc environment, which forms a key aspect for elucidating the Precambrian basement architecture and evolution of the Tarim craton. Recently, a deep well called Tarim Geological Survey Well (X1) was drilled from the northwest Tarim basin. Sixty-six samples were collected from the Sugetbrak Formation of the X1 well, including 6...
