吉林省新生代火山活动极其频繁,火山岩分布十分广泛。本文利用钾氩全岩体积法年龄数据21个,C_(14)年龄数据3个,及一些其它可资对比的C_(14)年龄数据、热发光年龄数据和古地磁年龄资料,结合野外地质地貌观察和古生物证据,尝试对这些火山岩进行同位素编年。这项工作对于建立该区的新生代地层年表,重建构造运动的历史,预测未来的构造运动,以及探索某些矿产的形成规律,无疑是有一定意义的。
Cenozoic volcanic activities in Jilin Province are extremely frequent, volcanic rocks are widely distributed. In this paper, 21 K-Ar volume data, 3 C_ (14) age data and some other C_ (14) age data, thermoluminescence age data and palaeomagnetic age data are combined. Observations and palaeontological evidence are used to conduct isotopic dating of these volcanic rocks. This work undoubtedly has some significance for establishing the Cenozoic stratigraphic chronology, reconstructing the history of tectonic movements, predicting future tectonic movements and exploring the formation of certain minerals.
