SEDIMETHOLOGICAL RESPONSE TO POSTGLACIATION CLIMATE CHANGE IN SOUTHEAST BULGARIA.

The most recent glacial period span in the interval 110,000 to 10,000 years ago. Recent geomorphologic studies in the Eastern Thracian plane have shown significant change in the sedimentation rates since the Younger Driass (between 10,800 and 9500 BC), which may provide a new inside on the climatic evolution of the region. It was found that all local rivers are in an aggradation phase, depositing up to 3 m thick mudstone deposits on top of a colder climate's well-washed, coarse sandstones. The aggradation resulted in sediments covering or eroding some human settlements dated 1 500 -- 1 200 BC, which originally were built above the flooded river terraces but now are found in the lowest flooded terrace.
