Optically stimulated luminescence (OSL)-thermometry can be used to reconstruct the thermal structure in slowly denuded regions where infrared stimulated luminescence (IRSL) signals of samples obtained from deep boreholes are measured and evaluated with depth. Only one study had explored this approach, using a target mineral of Na-feldspar. We applied multi-OSL-thermometry to K-feldspar obtained from deep borehole core samples drilled at the Tono (MIZ-1) and Rokko regions (Kabutoyama), which are well-documented thermally stable crustal environment. For the K-feldspar obtained from the MIZ-1 core, the inverted temperatures for the IRSL50 C of the samples at a depth of 1 km (40 C) were consistent with the in-situ temperatures. The results suggest that the application of OSL-thermometry to K-feldspar in a borehole is useful to reconstruct the palaeothermal condition. In this presentation, we will also show the results of the Kabutoyama core to draw more comprehensive conclusions.

Optically stimulated luminescence (OSL) thermochronometry is a tool for constraining cooling histories in low-temperature domains (several tens of degree Celsius) during the past 10-100 kyr. This method is currently applied only to rapidly denuded regions (about 5 mm/yr), because luminescence signals in slowly denuded regions saturate before the rocks are exhumated to the surface. However, cooling histories in slowly denuded regions may be constrained if unsaturated samples are obtained from deep boreholes. We applied multi-OSL-thermochronometry to the deep borehole core drilled at the Rokko Mountains, Japan, where slow denudation rates (0.1-1.0 mm/yr) are expected from previous studies. We used the Kabutoyama core collected by National Research Institute for Earth Science and Disaster Resilience. The total length of Kabutoyama core is 1,313 m and we collected the samples at 408, 642, 818 and 1048 m for OSL-thermochronometry. We found that the sample temperatures remained around the present ambient temperature at each depth for the last 0.1 Myr, indicating that the Rokko Mountains is topographically stable, which was consistent with previous findings. Thus, the thermal denudation history of slowly denuded regions may be constrained by multi-OSL-thermochronometry using samples from deep borehole cores. However, the denudation rates in the Rokko Mountains were too low and could not be determined by this method.

The interaction between rates of Earth surface processes, tectonics and climate is particularly pronounced in high mountain regions. However, understanding the interplay between these variables is complicated, in part due to the difficulties of measuring changes in the rates of Earth surface processes at the timescale of glacial-interglacial cycles. Here we investigate the potential of ultra-low temperature thermochronometers based on the luminescence and electron spin resonance (ESR) of feldspar and quartz minerals respectively for understanding changes in exhumation rates in the Hida range of the Japanese Alps. The Japanese Alps bisect the main island of Honshu, uplifted throughout the Quaternary and reach elevations of up to 3,000 m. The youth of these mountains has made measurement of their exhumation histories challenging and we particularly focus on Tateyama, which was glaciated throughout the late Quaternary period. We collected eight samples and analysed them using both luminescence and ESR thermochronometry. Our results show that whereas the luminescence signals of all samples are either in, or close to their upper dating limit (saturation), the ESR signals have the potential to yield finite exhumation rates for this region. We measured the ESR dose response and thermal decay properties of all samples, specifically targeting the Al and Ti centres. Whilst the Ti signals of some samples are saturated, the Al signals of all samples can be inverted to determine rates of rock cooling. Initial inversions reveal rock cooling rates on the order of 80 deg. C/Ma, far beyond the resolution of the luminescence thermochronometry technique. The next step of our investigation is to invert these data to determine rates of rock exhumation, and to relate these values to the climatic (glacial) and tectonic history of the Tateyama region.

Young plutons of 10-0.8 Ma, including the world's youngest Kurobegawa pluton, are exposed in the Kurobe area of the Hida Range, central Japan, indicating rapid rock uplift and exhumation in the Quaternary. However, reconstructing the exhumation history has been challenging because interpretations of the thermochronologic data are difficult due to the complicated, recent and active thermal history/structure. Here we are determining the exhumation history by estimating formation depths and ages of the young plutons based on Al-in-Hb geobarometry and zircon U-Pb geochronometry, respectively. At JpGU2021, we reported the preliminary results based on three datapoints from the ~5 Ma plutons and one datum from the ~0.8 Ma pluton, suggesting the three following interpretations: (1) formation depths of ~5 Ma and ~0.8 Ma plutons were estimated to be ~6-9 km, which indicates an increase of the exhumation rate after ~0.8 Ma, (2) mean exhumation rate since ~0.8 Ma was computed at 8-10 mm/yr in the Baba-dani area, (3) the formation depths are uniform in the E-W direction, disagreeing with the eastward tilting model. As of January 2022, we have obtained 14 datapoints in total: five from the ~5 Ma plutons, two from the ~2-1 Ma plutons, five from the ~0.8 Ma plutons, and two from the 
65 Ma plutons. These additional data are basically consistent with the previous data, reinforcing the three interpretations above. Recently, new uplift models of the Kurobe area were proposed, in addition to the eastward tilting model. Ito et al. (2021) suggested that the Kurobegawa pluton is a resurgent pluton of the Jiigatake caldera and was uplifted by the resurgence. Kawasaki (2021) proposed that displacements related to the E-W compression are localized along the Kurobe area due to the high geothermal gradient caused by presence of thermal fluid interstratified layers. We are planning to discuss consistency between our data and these two models.
