  • A common problem in single grain fission track analysis by the external method is the detection of component ages when a sample contains grain with several different true ages．Further analysis is required if the ages failed to pass the x2 test．This paper introduces the maximum likelihood method for the estimatida of proportions and agesd age components．The method is applied to three core samples from Subei basin．The 144 single grain ages from these samples failed to pass the x2 test and our analysis yields two true age components for these grains(70 Ma and 167 Ma)．This result shows that there exist two different provenances for the sedimemts from Subei basin,which is in Line with the previous sedimentological studies．

Abstract: A common problem in single grain fission track analysis by the external method is the detection of component ages when a sample contains grain with several different true ages．Further analysis is required if the ages failed to pass the x2 test．This paper introduces the maximum likelihood method for the estimatida of proportions and agesd age components．The method is applied to three core samples from Subei basin．The 144 single grain ages from these samples failed to pass the x2 test and our analysis yields two true age components for these grains(70 Ma and 167 Ma)．This result shows that there exist two different provenances for the sedimemts from Subei basin,which is in Line with the previous sedimentological studies．
