摘要
综述了近十几年来磷灰石裂变径迹(AFT)分析在基础理论上的进展:AFT退火动力学的影响因素;AFT多元退火模型的建立;LA-CP-S裂变径迹定年及AFT分析自动化.总结了一些尚存分歧的研究问题:围压对AFT退火过程的影响;AFT年龄与磷灰石(U-h)/He年龄的异常;特殊地质环境下AFT退火资料对退火模型的制约.最后展望了AFT分析的发展方向.
In this paper, some major progresses in fundamental studies of apatite fission track （AFT） analysis during the past decade are reviewed, which include the kinetic parameters that affect AFT annealing and their effects, multi- kinetic model for inverse modeling of AFT data, AFT dating using laser ablation ICP MS and Automated AFT analysis. In addition, some problems remaining debatable are summarized, including the pressure dependence or independence of AFT annealing; the discrepancy between AFT and apatite （U-Th）/He ages; and the combination of specific geological AFT annealing data to re calibration of existing AFT annealing models. At last some prospects of the AFT analysis are concluded.
