Steps towards surface dating using luminescence

摘要

Whereas luminescence dating applications usually avoid gradients and therefore surfaces, this study explores the requirements and possibilities of dating surfaces using infrared stimulated luminescence. The basic prerequisite for dating applications is a dose-dependent, bleachable and stable luminescence signal. It was found to be fulfilled for crushed granite rock material. Depth profiles below polished surfaces of granites indicate that a well bleached layer below the actual surface solely contributes to the infrared stimulated luminescence signal. A new measurement device, designed for in situ surface dating applications, is presented along with first experimental results. (C) 2000 Elsevier Science Ltd. All rights reserved. [References: 8]
