Pollen analysis and palaeobotany of impression bearing sediments in the lower Karewas
The paper describes a comparative account of pollen content and the megafossils in the Lower Karewa deposits at Ningle Nullah, Laredura, Dangarpur and Liddarmarg.
At Ningle Nullah pollen analysis reveals dense Oak woods although not a single leaf impression of Quercus has been found in the megafossils. At Liddarmarg, Dangarpur and Laredura the dominance of Quercus among the leaf impression is not equally reflected in the pollen spectra. Conifers absent in the megafossils are represented by low frequencies. Members of Lauraceae, Rosaceae, Papilionaceae, Cornaceae, well represented among megafossils, are absent or poorly represented in pollen record. Trapa abundant in megafossils is either absent or extremely rare in pollen spectra.
The paper emphasises the importance of both micro-and megafossil data in the reconstruction of past vegetation.
