“…Multiplealiquot methods were used, and the large uncertainty might be a consequence of incomplete resetting of the OSL signal prior to deposition. Tanaka et al (2001) present quartz OSL ages for known-age uvial deposits up to 60 ka in age, but their OSL age estimates are scattered and troubled by uncertainties in the water content of the material. Moreover, the independent age control is not presented in their paper, which makes assessment of the validity of the comparisons problematic.…”

Wallinga, J. 2002 (December): Optically stimulated luminescenc e dating of uvial deposits: a review. Boreas, Vol. 31, Optically Stimulated Luminescenc e (OSL) dating allows age determinatio n of sediments deposite d during the last glacial-interglacia l cycle. This relatively new technique therefore enables chronologica l frameworks to be establishe d for uvial deposits that often cannot be dated by other means. The OSL signal of quartz and feldspar minerals is reset by light exposure during uvial transport , and builds up as a result of ionizing radiation after burial of the minerals. Incomplete resetting of the OSL signal because of inadequat e light exposure in the uvial environmen t can result in age overestimations , especiall y for relatively young samples. Methods used for the detection of incomplete resetting , or poor bleaching , are reviewed. It is argued that technique s measuring the OSL signal from small subsamples (aliquots) are most promising for detecting poor bleaching and for obtaining the true age for a sample in which not all grains had their OSL signal completely removed at deposition . Quartz should be the mineral of choice, because it has been shown to yield the most reliable results and because its OSL signal is more rapidly reset than that of feldspar . Aliquot size should be small, with aliquots ideally consistin g of a single grain of quartz for samples in which the majority of grains are poorly bleached . Using single-aliquo t dating of coarse-grai n quartz, age offsets between zero and a few thousand years have been found for modern uvial deposits. The validity of single-aliquo t quartz OSL dating has been demonstrated by application to known-age samples, but for the older age range ( > ¹13 ka) further proof of the accuracy of the method is essential . The applicatio n of quartz OSL dating to investigation s of uvial deposits opens a new realm of possibilitie s to be explored , as is highlighte d by some examples of geologica l applications .

Alluvial fans are sensitive recorders of both climatic change and tectonic activity. The ability to constrain the age of alluvial-fan sequences, individual sedimentary events and the rates of sediment accumulation are key for constraining which mechanisms most control their formation. Recent advances in optically stimulated luminescence (OSL) measurement and analysis have resulted in vast improvements in the dating technique mad reliability of age determinations, particularly for OSL dating of quartz grains, and routine application to a wide variety of depositional environments is now possible. Here we apply OSL methods to date a variety of deposits within Late Pleistocene conglomeratic alluvial sequences in NW Argentina. The ages obtained range from 39 to 83 ka and were determined from debris-flow-and fluvial-dominated deposits and lacustrine sequences in intramontane basins bounded by tectonically active mountain ranges with as much as 2 km of relief. With careful choice of facies and sample collection, OSL techniques can be used to date Late Pleistocene, predominately matrix-supported, cobble-conglomerate alluvial deposits.

“…Tanaka et al (2001) compared multiple aliquot additive dose (MAAD) and regenerative dose (MAR) protocols for quartz from fluvial terrace sediments; they observed very different equivalent doses (D e ) from the two approaches. They also used a single aliquot regenerative dose (SAR) protocol for 48 single quartz grains for one sample and obtained widely scattered D e values.…”

Quartz grains from sediments in Japan are derived from complex mixtures of sources, including volcanic, plutonic, metamorphic and sedimentary rocks. We have measured the OSL signal of quartz grains from modern coastal sediments derived from different source rocks and compared these characteristics with the likely source. Each sample shows a different combination of various OSL components. It is concluded that the source rock affects the characteristics of the OSL components from quartz grains in Japanese sediments. By comparing the LM-OSL signals from volcanic sources with those from various source rocks, it can be deduced that quartz which has a higher fast component ratio is more suitable for dating. We also conclude that volcanic source areas should be avoided.
