在地壳上部几米的原位生成的宇宙成因核素，包括Be-10（T-1/2 = 1.5x10（6）年）和Al-26（T-1/2 0.73x10（6）年）的深度剖面图可用于研究表层沉积过程，量化剥蚀和埋藏速率，并阐明地貌演变和土壤形成的机制。在本文中，我们讨论了该方法的基本原理，并将其应用于两个红土序列位于非洲热带森林。(C)2000 Elsevier Science B. V.保留所有权利。
Depth profiles of in situ-produced cosmogenic nuclides, including Be-10(T-1/2 = 1.5 x 10(6) years) and Al-26 (T-1/2 0.73 x 10(6) years), in the upper few meters of the Earth's crust may be used to study surficial processes, quantifying denudation and burial rates and elucidating mechanisms involved in landform evolution and soil formations. In this paper, we discuss the fundamentals of the method and apply it to two lateritic sequences located in African tropical forests. (C) 2000 Elsevier Science B.V. All rights reserved.
