The applicability of both quartz and feldspar luminescence dating was tested on twenty-five samples from a marine succession now forming a cliff at Oga Peninsula, Honshu Island, Japan. The quartz shows thermal instability and linear modulated optically stimulated luminescence (LM-OSL) analysis revealed the dominance of a slow component. When compared with independent age control provided by two marker tephra, the quartz OSL ages grossly underestimated the depositional age. In contrast, potassium (K)-rich feldspar is a suitable dosimeter when measured using post-IR infrared stimulated luminescence (IRSL) at 225C, but it was found that the fading corrected ages calculated using dose rates based on sieved grain-size still underestimate. SEM analyses on the feldspar extracts revealed that the grains are amorphous with small crystalline inclusions; using standard internal dose rate parameters, this would result in a too large dose rate. Three different dose rate scenarios were considered for calculation: (1) sieved grain size (90-180m) and 12.50.5% K. (2) smaller grain size (4020m) and measured K concentration (60.5%), and (3) smaller grain size consistent with the observed crystal dimensions (4020m) and 12.50.5% K. The final dose rate scenario produces fading corrected ages that agree well with independent age control.

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.
