中文摘要:

在地质学研究和考古学研究领域,年代测定受到高度重视.释光测年由于其测年范围较大、测年材料多种多样、测年快速和在其整个测年范围内有较高的测年精度和准确度而得到迅速发展.但释光测年由于受特定因素的影响而使测年结果在有些条件下与样品真实的年代相差较大.在列举释光测年存在主要问题的同时,对这些问题的理论探讨方面在近十多年来取得的研究进展进行了评述.

英文摘要:

The luminescence dating has been concerned in geology and archeology area and advancing rapidly in recent years owing to its broader dating range, varied dating materials, rapidity in dating and high precision and accuracy in the whole of dating range. However some complicated factors influencing the luminescence dating may result in the difference between the sample ages dated with luminescence and their actual ages in some conditions. So some major problems existing in the luminescence dating process are discussed including separation of mineral, anomalous fading, sensitivity variation, and incomplete bleaching, etc. and the corre- sponding theoretical researches in its progresses in about a decade are reviewed as well.
