Organic Compounds in Lake Sediments,ds is largely a product of the past 15 years and has paralleled the development of modern analytical techniques such as combined gas chromatography-mass spectrometry. Although the identification of optical and geometric isomers needs more study, much progress has already been made in relating sedime

The Mineralogy and Related Chemistry of Lake Sediments,its surrounding surface and ground water drainage basins. Of course, lake bottoms have long been recognized as the depositional site of both mineral and organic matter that is transported to the lake from the drainage basin, as well as matter which forms and settles from within the water body proper

Freshwater Carbonate Sedimentation,ater chemistry, and biological activity limits generalizations about mechanisms of carbonate sedimentation. On the whole, in constrast to an oceanic environment, the bulk of primary lacustrine carbonates are inorganic chemical precipitates. Two distinctly different geological settings can be recogni

Stable Isotope Studies of Lakes,(.H/.H, usually written D/H), carbon (.C/.C), nitrogen (.N/.N) oxygen (.O/.O), and sulfur (.S/.S) have been used or have potential use in studies of various aspects of lakes. We give here a general overview of the processes which bring about changes in stable isotope ratios, using studies of lakes a

Chemical Models of Lakes,s sediments represent an open system which interacts with its environment (that is, with the drainage basin and the atmosphere) in different ways by exchanging energy and matter. Since some of the most important chemical transformations in the system are linked to biological processes such as photos
