 note = {Laser probe ^<40>Ar/^<39>Ar dating method can be divided into two types of applications. A pulse laser performs a pin point (5 microns) analysis on a thin section. A continuous laser can carry out step heating on a single grain When it comes to an application to young aged rocks, the 5-microns sample size by a pulse laser is too little to be detected. Depending on its application conditions, a minimum limit for a pulse laser may range from 10 Ma to 100 Ma. Successful step heating data was obtained in a order of 10 Ma on a single grain biotite. A key to the further improvement in determining young ages by the laser method is a precise measurement of ^<36>Ar after choosing a sample with a low atmospheric component (i.e. a high potassium content). This can be simply approached by making a sample size larger, partly losing the advantage using a laser., 第18回名古屋大学年代測定総合研究センターシンポジウム平成17(2005)年度報告 Proceedings of the 18th symposiumon on Chronological Studies at the Nagoya University Center for Chronological Research\
