Rockshelter Baaz in the Damascus region of Syria provided a variety of botanical remains from the Late Pleistocene and Early Holocene period. These remains provide new information about the vegetation evolution in this region. The earliest occupational levels correspond with a moisture peak during the Late Pleistocene, between ca. 34-32 kyr b.p., w...
Article
In order to provide new data on the neotectonics and geodynamic properties of western Syria, studies of marine terraces have been carried out. The most attention was paid to the lower terraces in the range of 3–5 to 30–35 m above sea level, because they have more complete distributions along the shore. The lower terraces were examined along the coa...

Dust is important in the Earth environment system. However, the role of dust in climate change remains largely unknown. A better understanding of the temporal and spatial variability of the dust accumulation in Asia forms an important step towards establishing the link between dust deposition and climate change. Here, a summary is given for the tim...
Article
Formation of mountains of the Central Tien Shan is usually explained by the isostatic response of the crust to its shortening caused by the India-Eurasia collision. The rise of the region in the period from Oligocene to Late Pliocene (2 myr ago) reached ∼700 m on average, which corresponds to the isostatic response. For the last 2 myr (Late Pliocen...

Loess-palaeosol sequences are widespread in the northern Black Sea coastal area. Unlike the quasi-continuous loess-palaeosol series in Central Asia and the Loess Plateau of China, the incomplete geological record of loess-palaeosol successions in Europe provokes different stratigraphical interpretations for different sections. Despite a long histor...

This review focuses on the loess-palacosol record across the Early-Middle Pleistocene transition to show the main structural features in key sections from the Loess Plateau of China via central Asia to Europe. Loess-palaeosol sequences in general demonstrate all impressive coherence with oxygen isotope oscillations, providing a high-resolution terr...
Article
A dependence of the magnetic susceptibility () on the alternation of paleosol and loess has been revealed for loess sections of southern Tajikistan: the value increases in paleosols and decreases in loesses. The magnetic signal intensification in the paleosol is caused by an elevated content of ferromagnetics. New electron-microscopic data on magne...

Complex characteristics of upper Pliocene-lower Pleistocene marine deposits filling the deepest part of the Al-Kebir depression near Lathakia, western Syria, are given. New biostratigraphic and paleomagnetic data allowed a detailed subdivision of the upper Pliocene-lower Pleistocene marine sequence. The position of the Pliocene-Pleistocene boundary...
Article
The chronology of loess in Central Asia was investigated by means of thermoluminescence dating (TL) in the 1970s, when age estimates ranging from 20 ka to over 800 ka were taken as providing an absolute chronology. This has caused major misinterpretation of Central Asian loess stratigraphy and palaeoclimatic reconstruction. We present a new TL stud...
Article
The loess-palaeosol succession of Central Asia is comparable with that of the Loess Plateau in North China. Palaeomagnetic investigations and palaeontological studies in South Tadjikistan suggest a date of 2–2.5 Ma for the oldest loess, indicating that dust storms became frequent in the region since 2–2.5 Ma BP. Under the prevalently arid and semi-...

... While technological characteristics form the basis of the classification, the degree of edge-damage and patination often can be used to establish a relative chronology for the materials from a single collection spot. Comparisons between vey finds and the materials recovered from stratified deposits in Yabroud (Rust 1950) and from the TDASP excavations at Baaz Rockshelter, Kaus Kozah Cave, Ain Dabbour Cave and Wadi Mushkuna Rockshelter (Conard 2006; Conard et al. 2008a Conard et al. , 2008c) serve as a useful check for the assessment of the artifacts into cultural groups (fig. 5,Table 1 ). ...
... The prehistoric site is located on the left eastern bank of the Bairaki balka (U-shaped gully; dry valley) incised into the 7th (Kitskany) Dniester terrace deposits up to the basal channel alluvium (Chepalyga, 1962). This terrace is defined in the Kitskany section, in which the alluvium comprises mammalian fauna of the Taman complex similar to its stratotype in the Sinyaia Balka site in the southern Azov sea (Dodonov et al., 2006(Dodonov et al., , 2008Markova and Vislobokova, 2016.). The alluvial deposits of the 7th Kitskany terrace exhibit reversed magnetization of the Matuyama paleomagnetic epoch, while in their upper part related to floodplain and oxbow lake facies the Jaramillo (0.98-1.07 Ma) paleomagnetic episode was found (Pevsner and Chepalyga, 1971). ...
... The sites from the Jordan Valley highlight the dynamic nature of land use systems in which those sites were located and offer additional information to the EMP territorial behavior pattern as well as information on the broader ecological boundaries imposed by a range of subsistence resources and the topography of the region. These surveys are consistent with outcomes from the surveys undertaken in other parts of the Levant such as the Negev highlands (Munday, 1977;Marks and Freidel, 1977), the region of El Kowm (e.g., Jagher et al., 2015) or the Damascus Province of Syria (Conard et al., 2004). EMP workshop sites with intensive blade production from the Zamliya-Munqiah area attest to a recurring presence of groups of blade makers in the region. ...

... The only clue for the age of the Orontes River Hattabian artefacts is that they are older than the terrace IV (h = 43-55 m) deposits. The latter contain remains of large mammals dated to the late Calabrianearly Middle Pleistocene (Trifonov et al., 2014) as well as handaxes and other tools of the middle Acheulian aspect (Clark, 1967(Clark, , 1968Dodonov et al., 1993). The data on the age of Khattabian artefacts within the Euphrates River terrace III a are more representative. ...
... Most of sites of the early part of the Epivillafranchian period in the south of Eastern Europe were formed by alluvial, deltoid or lagoon deposits (Sinaya Balka, Nogaisk, Sarkel, Port-Katon, Chishmikioy, Kairy, Tsimbal), and were deposited under prevailing warm to nearly subtropical conditions (Vereshchagin, 1957;Vangengejm et al., 1991;Dodonov et al., 2007;Shchelinsky et al., 2008). However, pollen spectra and small-mammal associations recovered from this region indicate a significant drop in temperature and a general trend of increasing aridity during the later part of the 1.2e0.9 ...
... Photographs by the author Proterozoic igneous and metamorphic rocks (Fig. 2) mantled by the Palaeozoic, Devonian, Carboniferous, and Palaeogene formations of volcanogenic and sedimentary (sandstone and limestone) origins filling the interior syncline depressions (the Bukhtarma and Zaisan Basins). The lack of vegetation and the intensive erosional processes disclose the rocky Pre-Cambrian and loose Mesozoic bedrock exposed to the present surface as remnant pediments (Fig. 4c) or buried by unconsolidated Cainozoic deposits (Fig. 4d) amassed in the intra-continental sedimentary basins (Aubekerov 1993;Dodonov 2002;Mikhailova 2002). The intensive erosion of the uplifted geological formations led to several denudation cycles flattening the former relief (Obruchev 1951). ...
... West 1997). Since the 1980s, large-scale river erosion within the major southern and central Siberian river basins as well as industrial activities disturbing the original surficial cover between the Irtysh River in the west and the Lena River in the east have revealed several hundred palaeolithic archaeological sites, some of potentially great antiquity (Derevianko et al. 1990;Deviatkin et al. 1992;Mochanov 1988;Ranov 1992). Apart from the Kuzbass and Angara Basins (Zudin et al. 1982;Medvedev et al. 1990), the most intensive research has been in the northern Minusinsk Basin in the steppe zone of the upper Yenisei River valley in the south of the Krasnoyarsk Region (Fig. 1). ...
