Pre‐Oxfordian (>163 Ma) Ophiolite Obduction in Central Tibet

We investigated subaerial to shallow marine strata of the Dongqiao Formation continental crust by 163 Ma that sit unconformably on Bangong‐Nujiang suture ophiolites that crystallized in a supra‐subduction zone setting at 189–181 Ma. Based on foraminiferal and coral studies, the depositional age of the Dongqiao Supporting Information: • Supporting Information S1 Formation is constrained to be Oxfordian and Kimmeridgian (Late Jurassic). Provenance analyses including • Data Set S1 detrital modes, geochemistry of detrital chromian spinels, and U‐Pb age populations of detrital zircons suggest the Dongqiao Formation was sourced from uplifted Bangong‐Nujiang suture ophiolites and sedimentary and metamorphic rocks of Lhasa terrane affinity to the south. We conclude that Correspondence to: Bangong‐Nujiang suture ophiolites were obducted soon after crystallization (prior to Oxfordian time; X. -

The 13 youngest marine sedimentary unit in the Najiangco area is the Upper Jurassic Shamuluo 14 Formation, which consists of sandstone, limestone, siltstone, and shale. Sedimentary facies 15 analysis shows that tidal flat and subtidal lagoonal facies characterized the northern margin of 16 the basin, while delta front and prodelta facies dominated the middle part, and carbonate shoal 17 and patch reef facies prevailed along the southern margin. Provenance analysis, including 18 petrographic modal analysis of sandstones and U-Pb dating of detrital zircons, shows that a 19 recycled orogen in the central Qiangtang to the north of Najiangco area was the source of the 20 sandstones in the Shamuluo Formation. Biostratigraphy and U-Pb zircon dating of a porphyritic 21 granitoid dike (150.8 ± 1.9 Ma) indicate that the Shamuluo Formation was deposited during 22 the Late Jurassic (Oxfordian to Kimmeridgian). -
