有人认为，考古遗址中岩石上的成土碳酸盐涂层可以用来重建新月沃地晚第四纪的环境变化。本研究将土耳其东南部的成童碳酸盐岩记录与其他三个当地或区域的古环境信息来源进行了比较，以评估这一新的代理与该地区其他独立数据的相关性：(1)利用考古遗址的古植物大遗骸作为生态指标；(2)利用文献和我们在6个中全新世考古遗址的调查中发现的古植物大遗骸的稳定碳同位素组成；(3)模拟新月沃地北部全新世降水和温度变化。比较涉及从湖泊沉积物中选择的孢粉和同位素数据，以及文献中提供的近东地区的洞穴同位素记录。虽然数据显示在区域尺度上代用记录有一定程度的变化，但对于北新月沃地（上美索不达米亚），它们表明了全新世环境史的三个显著特征：(1)全新世早期（约10000 - 6000cal BP）气温升高的趋势可能影响了该地区，(2)全新世中期（约5000 - 4000cal BP）水分有效度增加，温度相对较高，(3)4000cal BP前后水分有效度显著下降。需要进一步的研究来提高成土碳酸盐和植物大化石记录的年代学分辨率。这项研究强调了近东全新世古地理的复杂性，并强调了对该地区当地古环境信息来源进行仔细分析的必要性。
It has been suggested that pedogenic carbonate coatings on stones in archaeological sites can be used to reconstruct late Quaternary environmental changes in the area of the Fertile Crescent. This research compares a pedogenic carbonate record from southeastern Turkey with three other local or regional sources of palaeoenvironmental information in order to evaluate the correlation of this new proxy with other independent data from the area: (1) ancient plant macroremains from archaeological sites as ecological indicators, (2) stable carbon isotope composition of ancient plant macroremains available in the literature and from our own investigations in six mid-Holocene archaeological sites, and (3) modelled Holocene precipitation and temperature changes in the northern Fertile Crescent. Comparison involved selected palynological and isotopic data from lacustrine sediments as well as speleothem isotopic records in Near Eastern locations available in the literature. Although the data show a certain amount of variation of proxy records on the regional scale, for the northern Fertile Crescent (Upper Mesopotamia) they suggest three pronounced features of the Holocene environmental history: (1) a trend toward warmer temperatures may have affected the area during the early Holocene (between ca. 10,000–6000cal BP), (2) increased moisture availability and relatively high temperatures in the mid-Holocene (ca. between 5000 and 4000cal BP), and (3) a significant decrease in moisture availability around 4000cal BP. Further research is needed to enhance the chronological resolution of both pedogenic carbonate and plant macrofossil records. This study stresses the complexity of the Holocene palaeogeography of the Near East and underlines the need for careful analysis of local sources of palaeonvironmental information in the region.
