The Karewas of Kashmir refers to which among the following types of deposits ?

The Karewas of Kashmir are thick, flat-topped mounds of lacustrine deposits that characterize the Kashmir Valley [2]. Formed during the Pleistocene period, these deposits originated when the entire valley was submerged under water due to the upliftment of the Pir Panjal Range, which impounded the natural drainage and created a massive lake [2]. These sediments consist of fine silt, clay, sand, and bouldery gravel, often containing fossils of mammals and peat [2]. Geologically, as the Baramulla Gorge was eventually created, the lake drained, leaving behind these elevated terraces [2]. While some researchers note fluvio-lacustrine or glacial influences in the sediment layers [3], the primary classification of Karewas in Indian geography is as lacustrine deposits [1]. They are economically vital for the cultivation of saffron (Zafron), almonds, and walnuts [1].
