Lay Summary (German)

Lead
Das Erscheinungsbild der Landschaft in Bergregionen wird geprägt von der Interaktion zwischen Klima, sogenannten Oberflächenprozessen - etwa Erdrutschen oder Flusserosion - und Tektonik. Der Umfang dieser Interaktion bleibt jedoch ein umstrittenes Thema in der geowissenschaftlichen Forschung, weil es sehr schweirig ist, den Einfluss von Klima, Oberflächenprozessen und Tektonik zu trennen. Besonders stark ausgeprägt ist dieses Zusammenwirken in den japanischen Alpen. Es wurde hier bislang allerdings nur unzureichend untersucht. Ausgelöst durch Erdbeben werden in dieser Region riesige Sedimentmengen mobilisiert. Solche Sedimentflüsse können sich auf den Kohlenstoffkreislauf auswirken, und letztendlich sogar das Klima beeinflussen. Die schließlich im Nankai Graben (Pazifik) abgelagerten Sedimente k?nnen wiederum die Häufigkeit von Erdbeben beeinflussen.
Lay summary

Dieses Projekt widmet sich der Anwendung einer neuen Methode zur Rekonstruktion der eiszeitlichen Landschaftsentwicklung in den japanischen Alpen. Diese Methode heiβt „Lumineszenz-Thermochronometrie“ und basiert auf der Messung von Lumineszenzsignalen in Mineralien wie Quarz oder Feldspat. Die H?he des Lumineszenzsignals ist abhängig vom thermischen Gradienten innerhalb des Gesteins. Erodiert ein Gebirge schnell, kühlt das Gestein schnell ab. Ist die Abtragung gering, verläuft auch die Abkühlung langsamer. Modelle erlauben es deshalb die Erosionsrate von Gebirgen zu berechnen, und so die Wechselwirkungen zwischen Tektonik, Klima und Oberflächenprozessen besser zu verstehen.

Abstract

The height of mountain ranges evolve in response to tectonic uplift, erosion and climate change, but the feedbacks between these processes, particularly how topography records tectonic uplift, is poorly understood. The interplay between tectonics, climate and surface processes remains one of the most active debates in Earth Science. This feedback is particularly strong in the Japanese Alps, yet it has not been investigated. Landsliding is a key erosion process in mountainous seismically active terrain, and sediments released from erosion processes can enhance seismic activity through deposition within the subduction trench. Enhanced seismicity can result in increased landsliding further accelerating erosion rates. Organic matter entrainment within landslide debris and the weathering of silicate rocks influences the global carbon cycle, and can thus feedback onto climate. However recent studies have suggested that anthropogenic activity has reduced the sediment flux in Japan, potentially affecting feedbacks between erosion and seismicity. The objective of this proposal is to quantify erosion rates in the Japanese Alps over timescales of 10^4-6 yrs, and to elucidate the role it plays in linking climate with tectonics. Contrasting recent (10^0-3 yr) and historical (10^4-6 yr) erosion rates may also reveal anthropogenic effects on feedbacks between erosion, seismic and landslide hazards.Japan is one of the most tectonically active locations on Earth. It is situated adjacent to two triple junctions between four tectonic plates: the Philippine Sea, North American, Eurasian and North American plates. Within this convergent zone, the Japanese Alps are thought to have been uplifted within the last 1 to 2 Myr. Whilst undoubtedly tectonically driven, this mountain-building may also have been coincident with the onset of the Quaternary period, and the associated global climatic transition to ice-house conditions. Extremely high rates of precipitation (>3,000 mm/yr) coupled with earthquake enhanced landsliding potentially make the Japanese Alps one of the most rapidly exhuming places on Earth. However the rate of exhumation and the topographic evolution of this significant tectono-climatic setting remain poorly constrained. Quantifying exhumation rates will provide insights into the tectonic evolution of the Japanese Alps as well as an improved understanding of the coupling between tectonics and climate through erosion processes. Thermochronometry enables exhumation rates to be determined from the measurement of rates of rock cooling. The newly developed multi-OSL-thermochronometry system is sensitive to temperatures of as low as ~25 °C, enabling constraint of late-Quaternary exhumation histories at an unprecedented resolution. The use of multiple signals measured from different feldspar mineral extracts of the same sample enables the determination of precise cooling histories. OSL-thermochronometry techniques are applicable over timescales of up to 10^5 yrs because of saturation of the luminescence signal. Electron spin resonance (ESR)-thermochronometry is a related trapped-charge low-temperature thermochronometery system, sensitive to temperatures of ~50-80 °C, but which offers an advantage over multi-OSL-thermochronometry of later signal saturation at =10^6 yrs. This technique will be developed in this project to enable the complete Quaternary exhumation of the Japanese Alps to be resolved. Furthermore, whilst the limitation of signal saturation presently restricts the application of multi-OSL-thermochronometry to the most rapidly exhuming terrains, ESR-thermochronometry will be more widely applicable, and will be especially useful in areas where the application of (U-Th-Sm)/He apatite dating is challenging (e.g. New Zealand). Using an integrated approach of multi-OSL, ESR- and (U-Th-Sm)/He apatite-thermochronometry will enable the exhumation history of the Japanese Alps over timescales of 10^4-6 yrs to be precisely determined for the first time. Using these methods, exhumation rates will be quantified across the three main ranges of the Japanese Alps (the Kiso, Hida and Akaishi ranges), and their spatial and temporal variability investigated. Climate is relatively homogeneous across these ranges, providing ideal conditions to explore the relationship between exhumation and tectonic processes. Temporally consistent changes in exhumation rates across all ranges may reveal the effects of global climatic changes.
