Times Cited Count:1 Percentile:30.8(Geochemistry & Geophysics)The South Fossa Magna zone, central Japan, has been an active collision zone between the Honshu Arc and the Izu-Bonin Arc since the middle Miocene and provides an excellent setting for reconstructing the earliest stages of continent formation. Multi-system geo-thermochronometry was applied to different domains of the South Fossa Magna zone, together with some previously published data, to reveal mountain formation processes, i.e., vertical crustal movements. Nine granitic samples yielded zircon U-Pb ages of 10.2-5.8 Ma ( = 2), apatite (U-Th)/He (AHe) ages of 42.8-2.6 Ma (
= 7), and apatite fission-track (AFT) ages of 44.1-3.0 Ma (
= 9). Thermal history inversion modeling based on the AHe and AFT data suggested rapid cooling events confined within the study region at
6-2 Ma. The Kanto Mountains may have undergone a domal uplift in association with their collision with the Tanzawa Block at
5 Ma. However, this uplift may have slowed down following the migration of the plate boundary and late Pliocene termination of the Tanzawa collision. The Minobu Mountains and possibly adjacent mountains may have been uplifted by the motional change of the Philippine Sea plate at
3 Ma. Therefore, the mountain formation in the South Fossa Magna zone was mainly controlled by collisions of the Tanzawa and Izu Blocks and motional change of the Philippine Sea plate. Earlier collisions of the Kushigatayama Block at
13 Ma and Misaka Block at
10 Ma appeared to have had little effect on mountain formation. Together with a
90 deg. clockwise rotation of the Kanto Mountains at 12-6 Ma, these observations suggest that horizontal deformation predominated during the earlier stage of arc-arc collision, and vertical movements due to buoyancy resulting from crustal shortening and thickening developed at a later stage.

We are attempting to reveal uplift/denudation history of the Yoro-Suzuka-Nunobiki mountains, southwest Japan, by using apatite fission-track (AFT) thermochronology. We obtained AFT ages of 47-30 Ma. The ages are younger in the central and southern part of the Suzuka Range and get older to the north and south. Inverse thermal modeling based on the AFT ages and lengths indicates the difference among the ages reflect amount of denudation accommodate with the mountains uplifting in the past few million years. These results imply the process of the mountain uplifting of this area is more complicated than the developments of the basins propagating from south to north.

Fission-track (FT) and (U-Th-Sm)/He (He) analyses are used to constrain the denudation pattern and history of the Kiso Range. We obtained nine zircon FT ages (59.3-42.1 Ma), 18 apatite FT ages (81.9-2.3 Ma), and 13 apatite He ages (36.7-2.2 Ma). The younger apatite FT and He ages are interpreted as a reflection of uplift of the Kiso Range. On the basis of the distribution of the ages, we propose westward tilting uplift of the Kiso Range between the Inadani Fault Zone (IFZ) and StF. Based on thermal history obtained from apatite FT inverse modeling, we estimated denudation rates at 1.3-4.0 mm/y and maximum bedrock uplift rates at 3.4-6.1 mm/y since ca 0.8 Ma, the initiation of uplift of the Kiso Range.

Thermochronometric methods are used to identify the denudation history of the Akaishi Range, which has been uplifted since the late Pliocene. ZHe grain ages range 21.5-3.0 Ma and systematically younger to the east, implying a westerly tilting uplift of the Akaishi Range. We estimated denudation rates at 1.2-2.2 mm/yr or more in the Akaishi Range. These high denudation rates imply the topography of the Akaishi Range reflects post-uplift factors, e.g., spatial distribution of bedrock uplift rates and various denudation processes, rather than inherited geometry from the pre-uplift topography. Considering younger AFT ages previously reported in the southern part of the Akaishi Range, the Akaishi Range is considered to have had at least two uplifting stages, i.e., uplifting of the northern part since the late Pliocene and uplifting of the southern part since 1 Ma, probably attributable to reverse faulting of ISTL and collision of the Izu block to the south Fossa Magna area, respectively.

We are attempting to reveal uplift and denudation history of the Suzuka Range, southwest Japan, by using apatite fission-track and (U-Th)/He thermochronology. The Suzuka Range is distributed along the tectonic boundary of the reverse fault dominant Kinki district and strike-slip fault dominant Chubu district, which is thought to be a reflection of the Philippine Sea Plate slab geometry in this area. We are planning to reconstruct uplift and denudation history of the Suzuka Range in the past few million years and discuss its geomorphological and tectonic implications.

We are attempting to reveal uplift and denudation history of the Yoro-Suzuka-Nunobiki Mountains, eastern margin of the Kinki Triangle, by using apatite fission-track and (U-Th)/He thermochronology. In the eastern margin of the Kinki Triangle, subsiding areas have moved to the north in the past few million years. On the other hand, our the thermochronological data indicate more denudation in the central and southern parts of the Suzuka Range than in the Nunobiki Mountains to the south in the past few million years. This observation can imply basin development and orogenesis of the study area are derived from different mechanisms.

The mountains are distributed along the tectonic boundary of the reverse-fault dominant Kinki district and strike-slip fault dominant Chubu district, being an important region to understand the Quaternary tectonics of the southwest Japan inner zone.
