Chemical analysis of a sediment core from Paradip Lake, Orissa and its application to environmental reconstruction for 450 years

In this paper an attempt has been made to study the palaeoenvironmental changes around Paradip Lake, Orissa on the basis of elemental variations in a 3-m sediment core covering a time span of 450 years. The result shows that there is a marked increase in alkali and alkaline earth metals prior to 290...

Summary:In this paper an attempt has been made to study the palaeoenvironmental changes around Paradip Lake, Orissa on the basis of elemental variations in a 3-m sediment core covering a time span of 450 years. The result shows that there is a marked increase in alkali and alkaline earth metals prior to 290 years BP, indicating a period of intensive soil erosion and biotic activity. This is probably due to unstable landform conditions as a result of poor vegetational cover.
