裂变径迹技术是解决各种与时间—温度相关的地质问题的一种低温年代学手段。与磷灰石相比,锆石裂变径迹具有较高的封闭温度和退火区间,有其特定的地质意义和应用。自20世纪90年代以来,开展了大量锆石裂变径迹退火的研究,包括退火特性、径迹测量、退火模型,以及来自露头和钻孔样品的退火研究。首先介绍了锆石裂变径迹的分析程序、测量标准、实验退火模型,并比较了不同手段所得到的封闭温度及部分退火区间;其次概述了锆石裂变径迹的主要应用,包括盆地物源及热历史,造山带冷却剥露过程,以及断裂的热改造作用等方面,指出裂变径迹与(U-Th)/He方法的结合是以后的研究趋势。
Fission track technology is a cryogenic geochronology solution to various time-temperature related geological problems. Compared with apatite, zircon fission track has high sealing temperature and annealing interval, which has its specific geological significance and application. Since the 1990s, a large number of zircon fission track annealing studies have been conducted including annealing characteristics, track measurements, annealing models, and annealing studies from outcrops and borehole samples. Firstly, the analysis program, measurement standard and experimental annealing model of zircon fission track are introduced, and the sealing temperatures and partial annealing intervals obtained by different methods are compared. Secondly, the main applications of zircon fission track are summarized, including the source of the basin And thermal history, orogenic cooling and exhumation processes, and the thermal remodeling of faults, it is pointed out that the combination of fission track and (U-Th) / He method is the future research trend.
