Description 1520-1525
In this study fluctuation of the Caspian Sea
level in recent century was
determined by surveying the sediments types,
facial changes and calcium amount
in sediment samples. Study was done by collecting
3 sedimentary cores of the Southern shores of the Caspian Sea
in Sari region. In field operation after complete description
of the cores and
consideration of the color, organic matter content, sedimentation rate
and cohesion characteristics, etc, facies were
separated and from each facies a sedimentary sample was taken.
Findings suggest that there is a positive correlation
between the changes in calcium concentration in samples and the Sea water
level but a negative correlation between the Sea
water level and size of gravel in various periods. Indeed, it was found out that with an
increase in the amounts of calcium from surface (new) to depth (old) and
decrease in the percentage of gravel from the surface to depth the Sea water
level decreases.
