Abstract:
Lake like any body of standing water, serves as the repository for
materials carried into it by water, wind, ice, and the activities of living creatures. These
materials include:
Fine particles of minerals, rock fragments, and organics referred as sediments.
Sunken boats, bottles, cans, tires, fishing lures, etc. also found on the lake bottom are
not considered sediments.
Sediments of lake are studied in their varied aspects i.e. mineralogy,
texture, structure and clay content. While minerals, especially heavy minerals, are direct
indicators of source of material (Chaudhri and Gill, 1983), the texture and structures bear
imprints of environments during and after the deposition.
In this study, the sedimentation pattern of lake sediments worked out with
help of textural analyses is described as a case study of lake Agassiz, Canada (Gill &
Teller, 1989)
