Abstract

Abstract

The ³⁹Ar-⁴⁰Ar dating technique yields high-precision results, and all age data depend on accurate ages of National Standard Reference Materials that are irradiated together with the unknown age samples. Reference material is not only essential for obtaining ³⁹Ar-⁴⁰Ar isotopic age, but also the main factor to affect the quality of the ³⁹Ar-⁴⁰Ar age data. In order to eventually obtain accurate ³⁹Ar-⁴⁰Ar age, it′s is significant to develop reference materials with different age values. In this paper, Sanidine SK01 as the Cenozoic reference material of ³⁹Ar-⁴⁰Ar dating method was separated from hypabyssal quartz porphyry in the Fenghuo Mountain of Kekexili. Statistics of analytical data show that F value of ³⁹Ar-⁴⁰Ar of 0.857 was less than its threshold F value of 2.08, and its RSD of 0.66% was less than the required 5%. The good homogeneity of SK01 met the requirements of the national first-grade technical specification for standard materials as JJG 1006—1994. Through simulating the transport process, ³⁹Ar-⁴⁰Ar age analytical data showed that F value of 0.00697 was less than its threshold F value of 6.59, and its RSD of 0.58% was less than the required 5%, which proved samples maintained a good homogeneity during transport. In order to ensure the quality of ³⁹Ar-⁴⁰Ar dating, the minimum sample weight of 5 mg was recommended. The tests results indicated the homogeneity of Cenozoic sanidine SK01 is good, which satisfies the quantitative analysis of ³⁹Ar-⁴⁰Ar dating.
