英语例句
Studies of isochron luminescence dating with sand-sized grains. 粗颗粒的等时线释光方法研究。
The same samples were also dated by mineral Rb-Sr isochron method. 结果表明，花岗岩和片麻岩矿物的氧同位素温度大小顺序为：角闪石>磁铁矿>榍石>石英>黑云母>长石，遵循缓慢冷却条件下扩散控制的氧同位素交换封闭顺序，指示这些岩石没有受到后期热液蚀变的扰动。
It concludes with a discussion on the scientific validity of isochron dating. 这里包括许多等时线测年的科学有效性讨论。
Its age determined by Rb-Sr isochron is 306 Ma, suggesting that it was formed at Hercynian. 据Rb-Sr等时线测定,其年令值为306Ma,说明它形成于海西期。
Through K-Ar isotope age study in pillow basalt,has gained the isochrone age is 139Ma.The age is the formation age of pillow basalt. 在枕状玄武岩中获得K-Ar（全岩）同位素年龄为139Ma（测试单位：宜昌地质矿产所同位素室），因此确定其时代为晚侏罗世晚期。
