锆石裂变径迹分析 (ZFTA) 作为地质钟，基于 zeta 年龄校准和径迹长度测量。根据1）裂变径迹年龄的均匀性和2）对裂变径迹年龄的加热效应两个因素的组合，裂变径迹测年样品分为四种类型。四种类型的样品是（a）均质且未加热，（b）异质且未加热，（c）均质且加热以及（d）异质且加热。作为ZFTA应用于四类样品的例子，作者回顾了日本最近的裂变径迹测年研究如下：（a）房总半岛Kazusa群的火山灰层，（b）本州东北部仙台群的上新世广濑川凝灰岩段，（c）MITI“Honjo-oki”井和（d）MITI“Mishima”井。对两口勘探试验井的研究表明，ZFTA 是日本石油勘探的有用工具。
Zircon Fission-Track Analysis (ZFTA) as a geological clock is based on zeta age calibration and track length measurements. Fission-track dating samples are classified into four types according to combination of two factors of 1) homogeneity in fission track age and 2) heating effect to fission track age. The four types of samples are (a) homogeneous and unheated, (b) heterogeneous and unheated, (c) homogeneous and heated and (d) heterogeneous and heated. As an example of ZFTA applied to the four-type samples, the author reviewed recent fission track dating studies in Japan as follows: (a) volcanic ash layers of the Kazusa Group in the Boso Peninsula, (b) the Pliocene Hirosegawa Tuff Member of the Sendai Group in Northeast Honshu, (c) the MITI “Honjo-oki” well and (d) the MITI “Mishima” well, respectively. Studies on the two exploratory test wells show ZFTA is a useful tool for petroleum exploration in Japan.
