125th Anniversary International Symposium:

Geology for Society

6 September 2018

Conveners: Simon Wallis*(Univ. of Tokyo), Michiko Yajima(Nihon Univ.), Toru Takeshita(Hokkaido Univ.)

On the occasion of the 125th anniversary of the founding of the Geological Society of Japan (JGS), the Society has reaffirmed the need for geological studies to respond to societal needs and help tackle globally important issues such as natural disasters, environmental problems, natural resources, and energy. Our symposium follows this theme and representatives of the five Geological Societies with which the JGS has official exchange agreements—Korea, Taiwan (Geological Society Located in Taipei), Thailand, Mongolia, and London—will join representatives of the JGS, to give presentations explaining the ways in which geological studies interact with society, industry and the natural world in their respective countries and geographic areas. The aim of this symposium is to examine the current state of how geological studies contribute to society in areas with diverse natural and human environments and to deepen our mutual understanding of the directions in which geological studies need to develop in the future.

International Symposium:Paleoozoic Paleogeography of East Asia

18 September 2017

Conveners: Simon Wallis(Nagoya Univ.), Mark Williams(Leicester Univ.), Tatsuo Oji(Nagoya Univ.)

This session aims to bring together experts in the paleogeography of East Asia with special emphasis on the early Paleozoic. The main focus will be on the geology of Japan, but we will also present information from countries germane to elucidating the paleogeographical evolution of East Asia, such as Korea, Thailand, Vietnam and China. The methods presented will mainly focus on i) paleontology including the new results of recent studies and summaries of well-documented regions, and ii) geochronology, in particular U–Pb ages of detrital minerals. Some will be new research, some will be reviews of previous results. We think that trilobite studies are a previously under-used source of valuable information on paleogeography and intend to make this a special focus of the session. We hope to present the results of a review of trilobite collections from throughout Japan. This will be the first time information from all the substantial collections of trilobites in Japan has been brought together and assessed in the light of modern analytical techniques focussed on this group.

International symposium: Geological and paleogeographical evolution of the Ryukyu Islands in the late Cenzoic
Conveners: Yasufumi Iryu(Tohoku Univ.),HidetoshiOta(Univ. Hyogo/Mus. Nature and Human Activities),Kohsaku Arai(GSJ, AIST)

The Ryukyu Islands(Ryukyus)are situated to the southwest of mainland Japan and encompasses several tens of islands and islets, extending from Tane-ga-shima in the northeast to Yonaguni-jima in the southwest. Most islands in the Central and Southern Ryukyus are rimed by modern coral reefs and are covered with the Quaternary carbonates deposited in reefs and associated shallow lagoons and island shelves. The current terrestrial fauna and flora in the Ryukyus are characterized by a high frequency of endemic taxa. Based mainly on geological data including those for the Pleistocene fossils, some hypotheses were once presented for the paleogeographic changes, which supposedly caused coral reef‘turn-on’and gave rise to the current characteristic phylogeographical patterns in various terrestrial organismal lineages in the Ryukyus. However, recent molecular phylogenetic and evolutionary studies have yielded data that are obviously incongruent with those previous hypothetical scenarios. This symposium aims to integrate the latest geological and biogeographic data in the Ryukyus and create a new hypothesis for tectonic evolution of the islands.

Speaker(s) ; Shu-Kun Hsu(National Central University, Taiwan),Don Sunwoo(Korean Institute of Geoscience and Mineral Resources, Korea),Hidetoshi Ota(Univ. Hyogo/Mus. Nature and Human Activities),Mamoru Toda(Univ. Ryukyus),Koh Nakamura(Hokkaido Univ.)

International symposium: Geology of East Asia and Forensic Geology
Organizers: Simon Wallis* (Nagoya Univ.) and Koichi Hoyanagi (Shinshu Univ.)

–S2;Early Tectonics and Paleogeography of East Asia
Conveners: Simon Wallis* (Nagoya Univ.), Yasufumi Iryu (Tohoku Univ.), Mark Williams (Leicester Univ.), Tatsuo Oji (Nagoya Univ.)and Naomi Murakoshi(Shinshu Univ.)
From the eastern part of the Himalayan chain to the Japan ocean trench, east Asia contains some of the highest mountains and some of the deepest oceans in the world. The great variation in geomorphology in East Asia reflects the complexity of both the present geological setting and its long geological history. In this symposium we invite experts in paleogeography and related fields from different partner societies and the Geological Society of Japan, with the aim of offering a chance to exchange information on the tectonic history of eastern Asia, including the early geological foundations of the Japanese islands.

–S3;Development of Forensic Geology
Conveners: Ritsuko Sugita* (National Research Institute of Police Science)
This symposium forms part of the activities of the IUGS-IFG and aims to provide information on forensic geology from its origins to present day cutting-edge with presentations by forensic geologists from Europe and America. The symposium will focus on discussion of how geological material can be used as forensic evidence and thus contribute to society through helping to solve crimes. Forensic geology is part of the activities both of universities and private companies, and has recently been introduced as part of geological curriculum in some institutes. In Japan this field has been active for several 10s of years, although it has only recently become widely known. We hope this symposium will add to the growing interest in this field and help demonstrate how the geological characteristics of Japan may be used by forensic geologists.
