摘要
We report here Middle-Late Jurassic palynomorphs bearing sediments from the Lamayuru Complex, exposed along the Indus-Tsangpo Suture Zone in Ladakh. Apart from addition of new data towards understanding the geodynamics of the India-Asia collision zone, this will be helpful in understanding the formation of the slope-deep marine passive margin turbidites basin along the Indus Suture Zone, its palaeogeography and the processes of sedimentation and tectonics during subduction of the Indian plate beneath the Asian plate. The presently recorded Middle-Late Jurassic palynomorphs from the Larnayuru Complex also help to further strengthen our viewpoint that the Permian and Mesozoic palynomorphs bearing sediments were reworked from the Zanskar-Lamayuru Complex Tethyan realm and transported through. the Lamayuru Complex to the Nindam basin during ongoing geodynamic processes operative within the India-Asia trench-forearc subduction complex between Cretaceous-Palaeocene time span.
