Abstract The geochemical analysis of the shallow aquifer sediments of the area of investigation reveals that they are acidic in nature. The mean electrical conductivity of the deposits is 1.16 dS/m that indicates very low or negligible effects of salinity of the sediments of the Rangpur division. Th...

The Tista River is a tributary of the Brahmaputra River. The deposits that exposed along the both banks of the Tista River are characterized mainly by sand, sand laden with gravel and pebble with minor amounts of silt and clay. The X-ray Diffraction (XRD) of the clay sized sediments of the Tista Riv...

The petrographic study of the Dupi Tila Sandstone, Lalmai Hills, Comilla reveals the presence of both the detrital and authigenic (chemical) components. Detrital framework grains are sand-sized particles of either monomineralic (i.e., quartz, feldspar, mica, etc.) or polymineralic, i.e., rock fragme...
