Research Abstract

In 1996 : The following OSL properties were examined using quartz and feldspar course grains and fine grain samples ;
(1) Optical nleaching ; OSL intensity is 25% of initial intensity after 3-min exposure to 6000Lx sun light for fine grain sample from the Lake Ogawara,
(2) Temperature dependence of OSL intensity ; OSL intensity is intense with temperature, but unstable at the temperature higher than 90゚C.
(3) Intensity of OSL stimulated by 514nm and 860nm lights ; smoky quarts emit OSL by 860nm besides 514nm lights,
(4) TL after OSL measurement ; TL intensity after OSL measurements is strong enough to be applied for dating.
In 1997 : The following supplementary tests were made :
(1) Unstable fraction of OSL which is bleached by 50゚C,24h storage is related to an electron center which gives TL at about 160゚C,
(2) Dose dependence of quartz OSL differs from that of TL at high temperature region,
(3) Dose dependence of OSL is not necessarily linear,
(4) OSLs by 514 nm and 860nm excitation did not give the same ages. Above results were obtained from the data for lake sediment (Lake Ogawara) and sediments from Paleolithic sites (Sodehara, Toyama, Harase-kasahari, Ustinovka ets.).
The OSL age obtained for Ustinovka site are 7300 year for the siteIII 3rd layr, 10050 year for the siteIII 4th layr and 18600 year for the site VI 4th layr.
