at Lubana Lowland chronology (by Levkovskaya, 1987) of 15 regional subzones of BO3 (subzone 3), AT (subzone 4-8), SB (9-16) and SA (17) is based on 65 non-calibrated radiocarbon datings (by Levkovskaya G.M., 1987):
3: 7,7 - 7,5; 4: 7,5 - 7,3; 5: 7,3 - 6,6; 6: 6,6 - 6,4; 7: 6,4 - 5,9; 8: 5,9 - 5,3; 9: 5,3 - 4,5; 10: 4,5 - 4,3; 11: 4,3 - 4,2; 12: 4,2 - 4,1; 13: 4,1 - 3,8; 14: 3,8 - 3,6; 15: 3,6 - 3,3; 16: 3,3 - 2,5; 17: 5,5 - 1,8; kyr B.P.
- c. chronology of pollen zones and subzones in stratigraphical shemes of the region:
- Most important for palaeoecology pollen diagrams, that contain characteristics of:
- a. pollen standards: MM 15 (ZOZU standars - the diagram of peat without any archaeological finds and with 17 radiocarbon datings)
- b. geological sections with all or most of Holocene vegetational and climatic stages;
ZVI-A, ZOZU (see:MM 17);
- c. scalar climatic reconstructions (the result of using mathematic methods for climatic reconstruction);
MM 15
- d. sediments of sea- or lake-regressions and transgressions:
ZOZU, ZVI-A, ZVI-C, OSA-A, SULK-A, SULK-C, PIES-C, ZVES, EINI-A, ABOR-A, ABOR-D, LAGA-A
