Abstract

Archaeological excavations in the area of Gortalovo village, Pleven district (Middle Danube Lowland) found a cultural layer dated to 5000–4850 BC – the Late Neolithic period. The main practice of the agricultural and livestock breeding settlement established there was flint tools production. During the archaeological and interdisciplinary geomorphological field work buried sink-holes were found. Karstic landscape was covered with dark clayish soil, which was sampled for further sedimentological analysis. In the paper are presented the results from grain size analysis, which defines the characteristics of the top-layer and some indications of processes responsible for burying the karst features. The results showed that soil layer was developed on a karstified limestone, covered by loess sediments. The soil layer in the area is defined as heavy clayish chernozem and the middle soil profile responds to the filling of the dolines – darker and clayish.
普列文区戈尔塔洛沃村附近新石器时代晚期聚落地区的埋藏岩溶地貌
在普列文区(多瑙河中游低地)戈尔塔罗沃村地区进行的考古发掘发现了一个文化层,其年代为公元前 5000-4850 年--新石器时代晚期。在那里建立的农业和畜牧业定居点的主要活动是生产燧石工具。在考古和跨学科地貌实地考察期间,发现了被掩埋的水坑。喀斯特地貌上覆盖着深色粘土,对这些粘土进行了取样,以便进一步进行沉积分析。本文介绍了粒度分析的结果,该结果确定了表层的特征,并指出了造成岩溶地貌被掩埋的一些过程。结果表明,土层是在岩溶化的石灰岩上形成的,被黄土沉积物覆盖。该地区的土层被定义为重质粘土,中间的土壤剖面与溶洞的填充物一致--颜色较深,呈粘土状。
