... This study aims (1) to create a large data set from natural long-term annealing/diffusion experiments in thermally well-controlled settings, (2) to use this data set to test existing models and to use it as a base for new models, and (3) to develop and test a method of automation of the counting process of fission tracks. The long-term annealing/diffusion experiments will be carried out on ash layers of drill cores from oceanic borehols and on drill of the Kola super-deep drilling. The oeceanic environment gives a much better control of the long-term thermal evolution than a continental setting. The Kola borehole is situated in a techtionically passive setting on the Baltic Shield, far away from any orogenic activity. The automation of the fission track counting process follows the approach of a computer-guided identification system for recognizing and counting of nannofossils tested at the ETH Zürich.

...本研究的目的是（1）创建一个大的数据集，从自然的长期退火/扩散实验在热控制良好的设置，（2）使用该数据集来测试现有的模型，并使用它作为新的模型的基础，（3）开发和测试的裂变径迹计数过程的自动化方法。将对大洋钻孔岩芯的灰层和科拉超深钻井的钻头进行长期退火/扩散实验。海洋环境比大陆环境更能控制长期的热演化。科拉钻孔位于波罗的海地盾上的技术被动环境中，远离任何造山活动。裂变径迹计数过程的自动化遵循计算机引导识别系统的方法，用于识别和计数在苏黎世联邦理工学院测试的超微化石。
