摘要

研究人员于2001年测定了西班牙msamrida圆形剧场的4个石灰砂浆样本的年代，并于2019年用精确的测年方法重新测定了样本的年代，重点研究了溶解在磷酸中以后期二氧化碳组分释放的二氧化碳。这些样品很难确定年代，因为它们含有高度可溶的年轻碳酸盐污染物，这些污染物主要是在水解过程中与酸反应的早期阶段产生的二氧化碳。它们还具有很强的水力和丰富的镁，这可能会导致延迟硬化。然而，几乎没有死碳污染，因此晚期二氧化碳馏分给出了统一的14C年龄，指向公元1世纪晚期的弗拉维安，或更晚的圆形剧场。

The Roman amphitheatre in Mérida, Spain ˗Augustan or Flavian? Radiocarbon dating results on mortar carbonate

Abstract Four lime mortar samples from the Mérida amphitheatre in Spain were dated in 2001 and re-dated in 2019 with refined dating methods and focus on carbon dioxide that was released in late CO2 fractions when dissolved in phosphoric acid. The samples were difficult to date because they contained highly soluble, young carbonate contamination that dominated the carbon dioxide from the early stages of the reaction with the acid in the hydrolysis process. They were also rather hydraulic and rich in magnesium, which could have caused delayed hardening. However, there was very little dead carbon contamination so that late carbon dioxide fraction gave uniform 14C ages, pointing to a late 1st c. AD Flavian, or later age of the amphitheatre.

期刊介绍： Geochronometria is aimed at integrating scientists developing different methods of absolute chronology and using them in different fields of earth and other natural sciences and archaeology. The methods in use are e.g. radiocarbon, stable isotopes, isotopes of natural decay series, optically stimulated luminescence, thermoluminescence, EPR/ESR, dendrochronology, varve chronology. The journal publishes papers that are devoted to developing the dating methods as well as studies concentrating on their applications in geology, palaeoclimatology, palaeobiology, palaeohydrology, geocgraphy and archaeology etc.
