The article discusses the results of the latest interdisciplinary research of Czermno stronghold and its immediate surroundings. The site is mentioned in chroniclers’ entries referring to the stronghold Cherven’ (Tale of Bygone Years, first mention under the year 981) and the so-called Cherven’ Towns. Given the scarcity of written records regarding the history of today’s Eastern Poland, Ukraine, and Belarus in the 10th and 11th centuries, recent archaeological research, supported by geoenvironmental analyses and absolute dating, brought a significant qualitative change. In 2014 and 2015, the remains of the oldest rampart of the stronghold were uncovered for the first time. A series of radiocarbon datings allows us to refer the erection of the stronghold to the second half/late 10th century. The results of several years’ interdisciplinary research (2012-2020) introduce qualitatively new data to the issue of the Cherven’ Towns, which both change current considerations and confirm the extraordinary research potential in the archeology of the discussed region.

Oxygen Isotopic Analysis

Oxygen isotopic analysis and absolute dating of deep-sea cores show that temperatures as high as those of today occurred for only about 10% of the time during the past half million years. The shortness of the high temperature intervals (“hypsithermals”) suggests a precarious environmental balance, a condition which makes man's interference with the environment during the present hypsithermal extremely critical. This precarious balance must be stabilized if a new glaciation or total deglaciation is to be avoided.

Key Parameter

<p>In the search for very old ice, finding the age of the ice is a key parameter necessary for its interpretation. Most ice core dating method are based on chronological markers that require the ice to be in stratigraphic order. However, the oldest ice is likely to be found at the bottom of ice sheets, where the stratigraphy is disturbed, or in ablation areas, where the classical methods cannot be used. Absolute dating techniques have recently been developed to provide new constraints on the age of old ice, but their development in the context of ice cores is limited by the large sample size required. Here, we discuss the analytical performances of a new technique for 40Ar dating, which allows us to provide a reliable age with 80g of ice rather than 800g, as previously published. We present an application to the dating of the bottom of the TALDICE and Dome C ice cores. This method represents a significant advance for its application to the very precious ice at the bottom of ice cores.</p>

Abstract By synthesizing previous studies and the most updated archaeological data by typical stratigraphic contexts and assemblages, Hetao region cultural remains represented by li-tripods with double-handles should be considered part of the Shimao culture. With its core distribution area spanning from northern Shaanxi to central-northern Shanxi to central-southern Inner Mongolia, the development of Shimao culture can be divided into three phases: early, middle, and late. The absolute dating of the Shimao culture ranges from approximately 2300 BCE to 1800 BCE. The Shimao culture was therefore a major late Longshan archaeological culture in northern China that stands apart from its peers in the Central Plains.

AbstractThe sequence of three phases (Anathermal, Altithermal, Medithermal) of the Postglacial or Neothermal temperature curve, although demonstrably a reality, has been used improperly to determine absolute dates and past climatic conditions from archaeological deposits. A review of the historic development of the concept of the three sequent Neothermal temperature phases reveals the assumptions on which absolute dating of these phases has been based. Analysis of the variable radio-carbon dates now available for deposits attributed to these phases in a number of different localities in North America indicates that these phases cannot be considered as universal time periods bracketed by definite absolute dates; and consideration of the ecological diversity within North America at any particular time, especially in the West, indicates that climatic conditions inferred for a given span of Neothermal time in one area cannot be projected into another area without direct independent evidence of the actual climatic conditions which existed in the second area at that time. It is suggested that Anathermal, Altithermal, and Medithermal be used not as time periods with fixed absolute dates or climatic periods with defined characteristics, but rather be considered as phases of the Neothermal temperature curve which in different ecological areas resulted in locally varying climatic conditions which must be determined by direct evidence, dated by independent means, and designated by local terms.

Abstract An annually resolved and absolutely dated ring-width chronology spanning 443 years has been constructed using the historical and living-tree Scots pine samples from the Upper Silesia, south of Poland. The constructed regional chronology, based on six object chronologies, covers the period of 1568-2010. It is composed of 178 wood samples with the mean correlation of 0.51, mean series length of 104 years and mean EPS of 0.85. In total, 65 extreme years were distinguished. Their inde-pendent verification, based on the historical and meteorological data, showed significant correlation with the exceptionally cold/mild winters as well as severe droughts. The comparison of the extreme years with the other Polish pine chronologies showed similarities in the years with the anomalous winter conditions. Some extreme years can be associated with the exceptional pluvial conditions; these years are common in the Central European hydroclimatic tree-ring records. The construction of this regional pine chronology enables for the absolute dating of many architectural monuments from investigated region. The application of the new chronology for the dating of local wood can support interpretations of changes in the environment of the Upper Silesian region. In the future it can also be used as the basis for climate reconstruction.

Tripolye Culture

For a long time, the Eneolithic of the Don forest-steppe remained one of the least studied epochs in the archaeological scheme of the region. However, since the late 1960s, sites with materials of the Eneolithic have been actively explored on the territory of the Voronezh and Lipetsk Regions. By the 1980s, researchers had a concept for the development of copper-stone age cultures within the system of the Mariupol cultural-historical region of the Dnieper-Don-Ural interfluve, which is still relevant today. The criteria for distinguishing the Eneolithic era in the steppe and forest-steppe spaces of the East European steppe and forest-steppe were substantiated. The idea of their synchronization with complexes of the Tripolye A period was designated. The early Eneolithic in the Don forest-steppe was marked by the appearance of a population with specific ceramics of Nizhnedonskaya culture. Questions of the chronology of the early Eneolithic were solved exclusively by methods of analogies with the materials of neighboring territories and synchronization with the local Neolithic complexes. The paper deals with the problems of chronology, periodization and synchronization of materials from the early Aeneolithic of the territory of the Don forest-steppe. The focus is on the absolute dating of the Nizhnedonskaya culture of the Mariupol cultural-historical region and its synchronization with the early Tripolye Culture. According to all the data available to date, the regions early Eneolithic can be dated from 5300 to 4250 BC.
