ANGULAR DISTRIBUTION OF SPONTANEOUS FISSION TRACKS IN ZIRCON UNDER VARIOUS ETCHING CONDITIONS
《Chinese Science Bulletin》1992年第20期1688-1691,共4页翟鹏济 赵云龙 
Project supported by the National Natural Science Foundation of China
Ⅰ. INTRODUCTION When developing the technique of fission track dating, people found that the etching rates vary markedly with the crystallographic orientation of the etched surfaces so that the shapes of tracks are d...

AN IMPROVED ETCHING TECHNIQUE FOR FISSION TRACKS IN ZIRCON
《Chinese Science Bulletin》1991年第12期1012-1015,共4页翟鹏济 赵云龙 王世成 
Project supported by the National Natural Science Foundation of China.
Although it is more difficult to reveal spontaneous fission tracks in zircon than in apatite by chemical etching, the obvious advantages of zircon for fission track dating, such as relatively high uranium content, goo...
