Abstract
The systematical C-14 age of a large gagatite, which has been found in the pumiceous airfall deposits of the last large eruption of Changbai shan-Tianchi volcano, is dared from its centre to its edge. By fitting the C-14 age with the high precise calibrated curve of tree ring, it is concluded that the date of the last large eruption is (1215 +/- 15) AD. In addition, the climatic effects of that large eruption are also discussed, pointing out that the last large eruption probably corresp onds to the sulfuric acid peak at (1227 +/- 2) AD in GISP2 Greenland i ce core.
