Integrated lithofacies, microfacies and sequence stratigraphic framework of the Takche Formation (Ordovician- Early Silurian), Pin Valley, Spiti Himalaya, India

Ravi S. Chaubey et al.

Summary: An integrated litho-microfacies and sequence stratigraphic analysis was conducted on the Takche Formation (Ordovician-Silurian) in the Pin Valley, Spiti region. Ten lithofacies were identified, indicating deposition in a shallow marine carbonate ramp with highly fluctuating energetic conditions. The sequence stratigraphic analysis revealed three sequences, two maximum flooding surfaces, and five upward shoaling cycles, suggesting transgressive and regressive events. The presence of three disconformity surfaces resulted from submarine erosion or rapid fall in relative sea-levels.

Preliminary palynological study of the Upper Ordovician Pin Formation in northern Indian Himalaya

Wenhui Wang et al.

Summary: The Pin Formation in the northern Indian Himalaya may contain a record of the late Katian warming event, with palynological samples indicating a Late Katian age. The study of acritarchs and chitinozoans from this formation provides insights into Upper Ordovician biostratigraphy in the region, highlighting the need for further detailed studies with more samples to refine the understanding.
