“…Kaolinite was present in all the soils but in small amounts, although this mineral was dominant in four soils. Moslehuddin et al (17) and Moslehuddin et al (20) found a similar result in their study. Brady (21) and Jackson and Sherman (22) stressed that kaolinite represents a more advanced stage of weathering than does any other major types of silicate clays and formed from the decomposition of silicates under conditions of moderate to strong acid weathering environment, which results in the removal of the alkalies and alkaline earth metals.…”

“…This gives the impression that the major contribution of parent material might be from the Madhupur clay of adjacent Barind Tract. The presence of interstratified mica-vermiculite-smectite minerals as dominant minerals in the clay fraction has been reported from the terrace soils of Bangladesh (10,12,13,17,28) .…”

“…Moslehuddin et al (20) found similar results in clay fraction (<2 µm) of the lower Atrai basin soils. Reza et al (14) , Khan and Ottner (15) , Moslehuddin et al (16) , Moslehuddin et al (17) , Islam and Hussain (18) , Egashira and Yasmin (12) also found that mica was the predominant clay mineral in almost all floodplain soils of Bangladesh. Fanning and Keramidas (19) pointed out that mica in most soils originate mainly from soil parent materials and tend to weather to other minerals with time.…”

The lower Atrai basin, the study area, lies in the Agroecological Zone-5 (AEZ-5) of Bangladesh. This study reveals the clay mineral composition of top soils of seven different soil series viz. Binsara, Taras, Jaonia, Hasnabad, Laskara, Manda and Mainam developed in the basin. X-ray diffraction (XRD) technique was employed to identify and quantify the minerals. Results show that mica (41 to 59%) was the most dominant mineral among all soils except Laskara. In Laskara soils, the interstratified mica-vermiculite-smectite (41%) was the predominant mineral. Next to mica, kaolinite (10 to 12%) was found to be present in the Binsara, Taras 1, Jaonia, and Taras 2 soils. Chlorite (7 to 17%) was identified in all the soils and was found to be the second dominant mineral in the Manda and Mainam soils. In contrast, the interstratified mica-vermiculitesmectite (33%) was found to be the second dominant mineral in the Hasnabad soils. Small amounts of vermiculite mineral (1 to 13%) were identified in almost all the soils except Binsara. All the soils have interstratified mica-chlorite minerals (2 to 7%). A tiny amount of smectite (1%) was identified in Taras 1 soil. As far as the clay mineralogical composition is concerned, most studied soils were found at the initial stage of weathering, indicating the high potential to sustain low input subsistence agriculture.
