contents The data set comprises detrital zircon U-Pb geochronology from two Pleistocene (possible Plio-Pleistocene) sandstone deposits in West Sarawak. Deposits at Kampung Jangkar (TB72) were almost entirely sourced by the Upper Cretaceous Pueh batholith, and the detrital data can be used to constrain the intrusion age of the batholith at c. 80±0.6 Ma. Deposits in Petra Jaya (northern Kuching city; TB15b) show a heterogeneous age pattern, indicating recycling of the Kayan Sandstone from the Bungo Range area. In particular sample TB15b shows a number of Miocene to Pliocene zircons that indicate felsic volcanism in central Borneo in the Late Miocene to early Pliocene, which correlates to previously known mafic volcanism (e.g., Nuit Volcanics).
