Lichenometric dating is a cheap, relatively rapid means of dating rock surfaces, which has generally been overlooked in Australia. While lichenometry finds its greatest application in arctic and alpine geomorphological studies, there has been limited application to archaeological studies. This project set out to test the technique in south‐eastern Australia, and assess its usefulness for dating post‐settlement artefacts. The diameters of Buellia albula lichens growing on well‐dated memorials in the Bendigo cemetery were measured, and the relationship between age and lichen diameter established. The results indicate that B. albula can be used to determine the age of exposed cement surfaces from the 1890s to the present. The positive results suggest the technique should be investigated in other applications and environments in Australia, particularly where alternative dating techniques cannot be used. 相似文献

1946年复刊后的香港《华商报》是中共在香港创办的一份有重大影响的报纸,它不仅是宣传中共的坚强舆论阵地,也是联络统战工作的联络站。它内容丰富,涉及到政治、军事、外交、经济、文化等多方面,全面反映了解放战争时期国内外生动的历史画卷。它以其独特的方式积极探索了在资本主义条件下办社会主义报纸的特点,为今天媒体的换位思考可提供某些经验。 相似文献

重庆市开县余家坝墓地2002年发掘简报 总被引:1,自引:1,他引:0
开县余家坝墓地是长江三峡地区一处极为重要的战国时期巴人墓地。本年度共发掘墓葬13座,它们在墓葬形制、棺椁制度和随葬品组合上与以往发掘墓葬存在共性的基础上,也表现出了明显的自身特色,进一步加深了我们对余家坝墓地的延续年代、埋葬习俗和化特征等问题的认识。 相似文献
