Abstract
The isotopic documents of lake deposition are suitable potential means for studying the intercontinental, environmental and climatic conditions. In order to study the environmental and climatic conditions of Parishan area in Fars province in Holocene, a Core was taken with the length of 2m from the Parishan lake sediment. From this core, kernel time series was provided from documents of carbon and oxygen isotopes. Results show that during the study period, climatic changes because gradual increasing in the value of ∂O18 carb. This represents a weak dryness process in the area up to now. Contrary to this, carbon isotope documents during the study period show the more vigorous changes. Variability of ∂C13 carb values during the study period is known as the result of changes in the value of evacuation of underground waters to the lake. As it is observed in the process at ∂O18 carb throughout the study period, ∂C13 carb values have an increasing process, yet the observed changes in ∂C13 carb value are more vigorous than ∂O18 carb and it seems that variation of underground waters was not in complete harmony with dryness process of the area. It seems that achievement of underground waters around the lake in the form of well and aqueduct is the intensify factor for the reduction of underground inputs to the lake.
