- Аннотация: Macrocyclic multistage ground veins system was studied and AMS 14C-dated in archeological site Chongokni (about 50 km northern than Seoul) – very important archeological site of Southern Korea. The results of AMS-dating do not yet allow obtain exact chronology of Chongokni cyclic complex of ground veins, because there is the inversion of dates. More older 14C dates (31 - 35 ka BP) were obtained from the top part of section, but younger 14C date about 13 ka BP yielded lower than 1 m. Most likely it could specify later re-deposition of more ancient sediments, however the 14C date from hole could be explained by gnawer’s activity and removing of younger organic material downwards to a hole from the surface. Three important features already may be distinguished such as: 1) the sediments are dated from 13 up to 35 ka BP; 2) ground vein complex has multistage structure caused by cyclic-pulsing character of sedimentation; 3) ground veins formation most likely, is influenced by frozen cracking under more cold winter conditions in Late Pleistocene. The main result of 14C AMS dating is the Late Pleistocene age of multistage ground veins complex is established.analysis of upper tephra horizon shows about 25 ka BP – [1, 2, 3]; 2) ground vein complex has multistage structure caused by cyclic - pulsing character of sedimentation; 3) ground veins formation most likely, is caused by frozen cracking under more cold winter conditions in Late Pleistocene.
