The paper describes results of the pollen analytical investigations carried out at the 'ox-bow' lake adjoining the archaeological site at Malvan, Gujarat. The pollen sequence reveals the pre- valence of open conditions with the vegetation consisting largely of grasses and Cheno-Amaranths along with several other herbaceous elements. The presence of low percentages of high pollen producers, such as of Holoptelea and Myrtaceae suggests the occurrence of distant arboreal vegetation. Microforaminifera of the coiled and biserial forms have been found in abundance in most samples. Their absence at certain depths suggests the intermittent occurrence of estuarine conditions in the' ox-bow' lake. The pollen sequence suggests hardly any change in climate. The pollen grains of Pinus, Cedrus, Alnus and Betula were incorporated in the sediments due to long distance transport from Himalaya or Baluchistan either by sea or by wind.
