冰川的推进和火山活动的时间。本文根据日本中部希达山脉末次冰期晚期的三个冰碛物及其与火山喷出物的地层关系，阐明了立山（3,015 m）和立山火山。晚期的Stade被细分为立山Stades I（29 cal ka之前），II（18-20 10 Be ka）和III（10-11 10 Be ka）。在立山体育场I，晚期的冰川达到了最大的进展，并随着时间的推移而退缩。最大冰川推进发生在MIS 3 29 calka之前，同时发生在希达山脉的高山上。立山火山在立山I和立山II体育场之间引发了潜水爆炸，使爆炸坑上的熔岩层破碎。然而，熔岩碎片的坠落并没有引发冰川退缩和前进的开始。立山
The timing of the glacial advances and volcanic activities on Mt. Tateyama (3,015m) and Tateyama Volcano in the Hida Range in central Japan during the late stade of the last glacial period were clarified based on three moraines and their stratigraphic relationships with volcanic ejecta. The late stade was subdivided into Tateyama Stades I (just before 29cal ka), II (18-20 10Be ka) and III (10-11 10Be ka). The glaciers during the late stade attained their maximum advances in Tateyama Stade I and retreated with time. The maximum glacial advances during the late stade were caused just before 29cal ka in MIS 3 on the high mountains in the Hida Range simultaneously. Between Tateyama Stades I and II, the Tateyama Volcano gave rise to phreatic explosions that fragmented a lava layer overlying explosion crater. The fall of the lava fragments, however, did not trigger off the start of the glacial retreat and advance on Mt. Tateyama.
