ῌ !"Tectonostratigraphic division of accretionary-sedimentarycomplex of the Tamba-Mino-Ashio Belt and comparison
with the Northern and Southern Chichibu Belts# $*ῌ%& '**Satoshi Yamakita* and Shigeru Otoh**
Abstract : Primary division of any geologic unit must be descriptive but not conceptual. The tectonostratigraphic division of accretionary complexes should be based only
on litholgy and tectonostratigraphic position, just as the sedimentary stratigraphic
division of normal sedimentary complexes is based on lithology and sedimentarystratigraphic position. In this way the lithostratigraphic unit “formation” is also
applicable to accretionary complexes. If we introduce age of any kind of rock as acriterion into the tectonostratigraphic division, it may mislead us into wrong correlation.
According to the method of tectonostratigraphic division proposed above, theaccretionary complex of the Mino Belt is divided into eight formations : the Kasugano,
Imajo, Funafuseyama, Kamiaso, Nabi, Kanayama, Misogawa and Yabuhara Formations. The Kamiaso, Nabi and Kanayama Formations are grouped into the Hidagawa
Group. The eight formations are tectonically stacked from upper to lower in theabove mentioned order, although the three formations of the Hidagawa Group occupy
a same tectonostratigraphic horizon and laterally change into each other. Melanges
that include a large amount of chert and few greenstone and limestone blocks inmudstone matrix yielding Middle Jurassic radiolarians, e.g., the Kamihara Melange in
the Tanigumi area and the Shimashima Complex in the Kiso area, have been considered to di#er from the Kanayama Formation. However, they should be included into
the Kanayama Formation because of their lithological similarity and the possession ofa same tectonostratigraphic position. This tectonostratigraphic framework well applies to the Tamba and Ashio Belts. An eastward younging age polarity of mudstone isrecognized in the Imajo and Funafuseyama Formations through out the Tamba-MinoAshio Belt.
This tectonostratigraphic framework of the Tamba-Mino-Ashio Belt is basicallysimilar to that of the Northern and Southern Chichibu Belts, although some minor
di#erences are recognized between corresponding formations and some formations areabsent in the latter. In such a comparison, the Northern Chichibu Belt is similar to theTamba-Mino-Ashio Belt rather than the Southern Chichibu Belt.
key words : tectonostratigraphy, Tamba-Mino-Ashio Belt, accretionary complex, Jurassic,***  3  , () * ,***  ++  +0 ()+*
