The study comprises mineralogical composition of some selected horizons of Gerua and Kalma series.of Pleistocene clay deposits of Madhupur. Sand fractions in all the horizons contained quartz as the dominant mineral (> 80%) with feldspar and mica as minor minerals. Kaolinite, mica and small amount of quartz were the minerals found in the clay fractions. The relatively low content of weatherable minerals show that the soils developed on a parent material which were already weathered to a considerable degree.
