SHRIMP U-Pb zircon provenance of the Sullavai Group of Pranhita-Godavari Basin and Bairenkonda Quartzite of Cuddapah Basin, with implications for the Southern Indian Proterozoic tectonic architecture

Joy, Sojen; Jelsma, Hielke; Tappe, Sebastian; Armstrong, Richard

Description

Proterozoic basins in cratonic India, referred to as "Purana Basins", cover about 20% of the Archean basement of the subcontinent. Although the stratigraphy of most of these basins has been well established, it is only recently that radiometric age constraints have been obtained for some of the sedimentary sequences. This study provides new data for two of the Purana Basins in southern India using SHRIMP U-Pb analysis of detrital zircons. For the Pranhita-Godavari Basin, an age limit of 709. Ma...[Show more]
