摘要
地衣测年是20世纪50年代提出并逐渐发展起来的一种测年方法,已被应用于冰川地貌、古滑坡、古地震等地质事件的测年中,尤其在侵蚀速率较大、沉积物难以保存的地区具有独特的优势。虽然地衣测年仍不完善、在具体应用中存在一些问题、国内外学者对该方法也有争议,但随着研究的深入以及相关问题的解决,其对于全新世以来地质事件的测年具有广泛的应用前景。本文整理了地衣测年的发展历史和存在问题,并展望了地衣测年的未来发展方向。
Lichenometry is a kind of dating methodswhich wasput forward in the 1950 s and gradually developed,ithas been used in dating of ice landscape,ancient landslides,earthquake and other geological events,especially in theregions of large sediment erosion rate anddifficult to preserve the sediments,ithas a unique advantage.It is still not perfect in the specific application,there are some problems and controversies among domestic and foreign scholars,but with the deepening of the research and solution of related problems,itshows an extensive application prospect for dating geological events since the Holocene.This paper relates the development history of lichen dating and existing problems,and shows the prospects of the future development direction of lichen dating.
