Based on the geological survey of 1∶250 000 scale in Kana and Ritu Areas, the authors recognized the vertical and horizontal variation of sedimentation, studied the sedimentary environment and reestablished the Jurassic-Cretaceous sedimentary sequence in three strata areas of western Bangong Lake-Nujiang suture zone. It was specified that the sedimentation in Bangong Lake-Nujiang middle Tethys oceanic basin was clearly different from both the southern and northern continental margin of the ocean in Jurassic-Cretaceous period. The evolution of the middle Tethys Oceanic basin can therefore be divided into three stages as Early-Middle Jurassic deep-water ocean, Later Jurassic to Early Cretaceous relict basin with shallow-water sedimentary rocks and Later Cretaceous remnant oceanic basin withering away.
