Abstract:Lacustrine laminae are mainly deposited in lake water with obvious layering. Such factors as temperature, salinity and depth control the water layering. Some materials like algae, carbonate, organic matter, clay and silty sand can separately form different laminae in different seasons. The deposition of algae and organic matter is related to seasonal blooming of algae, and carbonate laminae may be related to chemical or biochemical deposition due to the blooming of algae. Clay and silty sand are transported by stratified current. In any cases, however, the variation in the deposition of laminae is closely related to the change of climates. Much importance has been attached to the application of laminae to deduce the changes of climates and environments in the past. Nevertheless, researches on the changes of laminae and the development of lacustrine physicochemical properties on the basis of periodic changes of climate remain to be conducted.
