摘要
Longgang volcanic swarm belongs to one of volcanic areas which have been active since modem times. In view of multiple eruptions during histories, it is very important to determine age of every eruption for evaluating volcanic hazards. The alkaline basalt samples taken from Dayizishan and Diaoshuihu are analyzed by U-series component method, after magnetic separation. The ages of the two samples are (71 +/- 9) ka, (106 +/- 13) ka before presence, respectively. These data indicate that there exist intensively eruptive activities during late Pleistocene.
