Abstract

Abstract A gravel horizon is preserved in several locations within the world-wide known archaeological site in Saqqara (northern Egypt). It is characterized by a variable thickness, composed of coarse, quartz, quartzitic and flint pebbles, and considered to correspond to gravels of the Edfu Formation, deposited in the Early Pleistocene by the early phase of the Nile development (Protonile Phase). This relatively short (ca. 200 ka) and at the same time very dynamic period of Protonile activity during the Edfu Pluvial is one of the most poorly recognized hydrological-climatic episodes of the Quaternary in north-eastern Africa. This paper is focused on the preliminary sedimentological-petrographic characteristics of these deposits and an attempt to indicate their source areas as well as mechanisms of transportation and deposition in the context of Pleistocene pluvial episodes.

埃及Saqqara考古遗址Edfu组早更新世砾石沉积环境的初步结果

在塞加拉(埃及北部)世界知名的考古遗址中，有几个地方保存着砾石层。它的特点是厚度变化，由粗粒、石英、石英岩和燧石卵石组成，被认为与尼罗河发育早期(原元期)沉积于早更新世的Edfu组的砾石相对应。这段相对较短(约200 ka)的埃德福洪积期原石活动非常活跃的时期是非洲东北部第四纪水文气候时期最不为人所知的时期之一。本文对这些沉积物的沉积岩学特征进行了初步研究，并试图在更新世洪积期的背景下指出它们的源区以及搬运和沉积机制。

期刊介绍： Studia Quaternaria is designed to publish scientific works concerning the Quaternary, on local, regional and global scale. Studia Quaternaria is interested in all fields of research dealing with stratigraphy and reconstruction of the past environments, including palaeogeography, palaeoecology, palaeoclimatology, palaeohydrology etc. The journal is also open to studies of natural environmental processes, and to recognition of mechanisms involved in the dynamics of our environment. The clue is that the Quaternary is still ongoing and vivid, and understanding of its past and present development support each other.
