Dear participants for pre-meeting excursion, |
Post-field excursion, Boso accretionary prism (Two days)
Two day field trip to Pleistocene Submarine Landslides in the Boso (27-28 October, 2011)
Tentative schedule:
27 Oct. 8:00 Participants meet at JR Kyoto Station,
8:30 Depart the Kyoto station of Shinkansen (Super express train),
11:00 Arrive at the Tokyo station and drive to the Boso by bus, Lunch,
13:00-17:00 Field observation
Stop 1: Submarine land slide associated with earthquake-induced liquified sediment flow;
Stop 2: chaotic rock body apparently due to methane explosion), 17:30 arrive at Hotel.
28 Oct. End of the field trip.
The bus will stop the Haneda International Airport and JR Tokyo station around noon. To the Narita International Airport: about 2 hours by shuttle bus or train. To the Kansai International Airport: about 1 hour flight from the Haneda Airport, ~3 hours by the Shinkansen. The transportation fee from Haneda Airport or Tokyo station is not included in the field trip fee.
Fee: ~35000 yen
We will visit a large-scale chaotic sedimentary body within Late Pliocene to Pleistocene trench-slope cover sediments of the Chikura Group, Central Japan. This body formed by earthquake-induced liquefaction and submarine sliding formed on the seafloor. Detail information on the outcrop are documented in the following paper:
Yamamoto, Y., Ogawa, Y., Uchino, T., Muraoka, S., and Chiba, T., 2007. Large-scale chaotically mixed sedimentary body within the Late Pliocene to Pleistocene Chikura Group, Central Japan, Island Arc, 16, 505-507.
If we have enough time, we will visit another chaotic rock-unit plausibly related to methane-hydrate explosion.
