1) cosmogenic isotopes
宇生核素
1.
Because of cosmogenic isotopes production, the concentration of cosmogenic isotope in surface layer of the exposed rocks accumulates more and more, and at same time, it becomes less and less with isotope′s radiation and surface′s erosion.

3) terrestrial in-situ cosmogenic nuclides
陆地宇生核素
4) in situ-produced cosmogenic nuclides

<Abstrcat>Cosmogenic nuclide techniques have been used widely in various Earth science areas to measure surface exposure ages,burial events,and to reveal the style and rates of landscape evolution processes across a wide range of spatial and temporal scales.
宇宙核素技术已广泛应用于地学研究的诸多领域,用来直接获取地质、地貌体的暴露年龄或埋藏时代,揭示本地、小流域、大区域范围的地表过程演化特点和速率。
2.
<Abstrcat>Cosmogenic nuclides found in rocks and sediments at the Earth s surface are produced primarily by three forms of interaction between cosmic rays and minerals: spallation,neutron-capture reactions and muon-induced reactions.
宇宙核素是宇宙射线与地表物质相互作用的产物,具有蜕变、中子捕获和介子反应三种形成机制。
补充资料：显生宇
| 显生宇 Phanerozoic Eonothem 显生宙形成的地层。主要特点是含有丰富的生物化石 ，因此可以应用生物地层学的方法进行地层的划分和对比。根据地层中生物化石的进化阶段，显生宇划分为古生界、中生界和新生界。 |
