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...
Parameters of OSL components of quartz in volcanic ashes and in tephric loess from Japan were determined, and their characteristic in terms of recuperation was investigated. As a result, the medium and slow1 components, which were the main components in the volcanic quartz, were also found in the quartz in tephric loess, while the OSL of quartz in tephric loess was dominated by fast component. This...
