Karewa Gr

Agarwal et al. (1989) regard commencement of the Karewa sedimentation around 3.8 Ma, coinciding with uplift of the Pir Panjal range. In the Rembiara section they identified five zones having paleomagnetic age exceeding 2.4 Ma, and Zone 6 coincides with lower part of Matuyama polarity chron. In this section the first two zones and half of third represent age between 1.8 to 2.4 Ma. The upper half of Zones 3 and 4 ranges from 1.8 Ma (Olduvai) and 0.7 Ma (Brunhes-Matuyama boundary). In the Romushi section, the succession begins from 2.4 Ma (Matuyama/Gauss boundary). The Zones S1 to 9 are covered by the Brūnhes Chron, hence are younger than 0.7 Ma. These dates have been corroborated by TL and HC dates. The top three paleosols indicate C14 dates of 5, 18 and +24 Ka, the fourth paleosol is older than 31 Ka. The top of triplet, the fourth by TL is dated at >47 ka. Based on these dates Agarwal et al., (1989) suggested that the Lower Karewa sedimentation terminated around 200 ka and the Jhelum River emerged ca 85 ka. The loess deposit has been dated within 200 ka. See individual formations for details.
