| บทคัดย่อ/คำอธิบาย | : | Lithological and mineralogical studies were carried out on sediments from a 650 cm long core from the north western Bay of Bengal at a depth of 2700 m. These studies demarcate a boundary at 380 cm designated as unit 1 from 0-380 cm and unit 2 from 380-650 cm. The sediments of unit 1 are dark yellowish brown color at the surface and light to dark olive grey colour downwards up to 380 cm. Texturally, it is comprised of clays and clayey silts. The coarse fraction contains well preserved foraminiferal skeletal remains. The total calcium carbonate (TCC) varies from 10 to 19% while the total organic carbon (TOC) ranges from 0.04 to 1.40%. Illite is the predominant mineral with concentrations varying from 49 to 60% followed by montmorillonite with concentrations between 22 to 36%. Chlorite content ranges from 12.8 to 29% and do not show any recognisable trend. |
