LA-ICP-MS U-Pb dating and REE patterns of apatite from the Tatra Mountains,Poland as a monitor of the regional tectonomagmatic activity

This study presents apatite LA-ICP-MS U-Pb age and trace elements concentrations data from different granite types from the Tatra Mountains, Poland. Apatite from monazite and xenotime-bearing High Tatra granite was dated at 339 ± 5 Ma. The apatite LREE patterns reflect two types of magmas that contributed to this layered magma series. Apatite from a hybrid allanite-bearing diorite from the Goryczkowa Unit was dated at 340 ± 4 Ma with apatite LREE depletion reflecting the role of allanite and titanite during apatite crystallization. Apatite crystals from a hybrid cumulative rock from the Western Tatra Mountains were dated at 344 ± 3 Ma. Apatite is one of the main REE carriers in this sample and exhibit flat REE patterns. Taking into account the relatively low closure temperature of the U-Pb system in apatite (350–550°C), the c. 340 Ma apatite ages mark the end of high temperature tectonometamorphic activity in the Tatra Mountains.     

The reflection of human activity in the sediments of Iwankowskie Lake from Subatlantic Phase (Polish Outer Carpathians)

The paper presents the analysis of organic and mineral sediments filling the depression, which developed over the landslide located at the slope (767–773 m a.s.l.) of Lubań ridge decscending to the Ochotnica river valley in the Polish Flysch Carpathians. The landslide formed in an early stage of the Subatlantic Phase (2490 ± 35 BP). The top of peat is dated at 1360 ± 50 years BP and is covered by 72 cm of clayey silts with some sandy intercalations, which indicate slopewash after deforestation. The pollen of ruderal plants and Cerealia (undiff.) reflect agricultural activity in the surroundings. The fragments of charcoal indicate the age of the forest clearance to the first half of the 17^th century. The late forest clearance at the elevated north exposed slopes followed 200–300 years later in relation to the foundation of the village at the valley floor.     

Mobilization of ore fluids during Alpine metamorphism: evidence from hydrothermal veins in the Variscan basement of Western Carpathians,Slovakia

Hydrothermal polymetallic veins of the Gemeric unit of the Western Carpathians are oriented coherently with the foliation of their low‐grade Variscan basement host. Early siderite precipitated from homogeneous NaCl‐KCl‐CaCl₂‐H₂O brines with minor CO₂, while immiscible gas–brine mixtures are indicative of the superimposed barite, quartz–tourmaline and quartz–sulphide stages. The high‐salinity aqueous fluid (18–35 wt%) found in all mineralization stages corresponds to formation water modified by interaction with crystalline basement rocks at temperatures between 140 and 300°C. High brominity (around 1000 ppm in average) resulted from evaporation and anhydrite precipitation in a Permo‐Triassic marine basin, and from secondary enrichment by dissolution of organic matter in the marine sediments at diagenetic temperatures. Sulphate depletion reflects thermogenic reduction during infiltration of the formation waters into the Variscan crystalline basement. Crystallization temperatures of the siderite fill (140–300°C) and oxygen isotope ratios of the parental fluids (4–10‰) increase towards the centre of the Gemeric cleavage fan, probably as a consequence of decreasing water/rock ratios in rock‐buffered hydrothermal systems operating during the initial stages of vein evolution. In contrast, buoyant gas–water mixtures, variable salinities and strongly fluctuating P–T parameters in the successive mineralization stages reflect transition from a closed to an open hydrothermal system and mixing of fluids from various sources. Depths of burial were 6–14 km (1.7–4.4 kbar, in a predominantly lithostatic fluid regime) during the siderite and barite sub‐stages of the north‐Gemeric veins, and up to 16 km (1.6–4.5 kbar, in a hydrostatic to lithostatic fluid regime) in the quartz–tourmaline stage of the south‐Gemeric veins. The fluid pressure decreased down to approximately 0.6 kbar during crystallization of sulphides. U‐Pb‐Th, ⁴⁰Ar/³⁹Ar and K/Ar geochronology applied to hydrothermal muscovite–phengite and monazite, as well as cleavage phyllosilicates in the adjacent basement rocks and deformed Permian conglomerates corroborated the opening of hydrothermal veins during Lower Cretaceous thrusting and their rejuvenation during Late Cretaceous sinistral transpressive shearing and extension.     

Charcoal in alluvium of mountain streams in the Bieszczady Mountains (Polish Carpathians) as a carrier of information on the local palaeoenvironment

Fragments of charcoal are present in floodplain alluvium of the San and Strwi?? rivers in the Polish part of the Bieszczady Mountains, Polish East Carpathians. They occur as single clasts or in lenses in the basal part of fine-grained alluvium, together with unburnt wood debris, or in the middle part of the vertical sequence of the floodplain alluvium. 14 samples of charcoal from the upper courses of the San (ca. 50 km) and the Strwi?? (ca. 10 km) were dated with radiocarbon. The obtained dates fall mainly in the 15^th through 19^th century interval; only one sample is markedly older (9^th–10^th century). Taxonomic composition of the charcoal source wood was also studied and compared with that of coeval forests. Correlation of the charcoal age with the history of economic development of the studied region indicates that charcoal is of anthropogenic origin: older charcoal from intense slash-and-burn deforestation, while younger charcoal was produced by local industries.     

Application of magnetic susceptibility on polished stone tools from Western Hungary and the Eastern part of the Czech Republic (Central Europe)

A non-destructive method – magnetic susceptibility (MS, κ) measurement – was used to characterize about 360 Neolithic, Copper and Bronze age polished stone tools of the Miháldy collection (Laczkó Dezső Museum, Veszprém, Hungary), composed of artefacts from three Neolithic (Moravian Painted Ware) workshops around a source of greenschist at Želešice near Brno (Moravia, Czech Republic) and semifinished artefacts from workshops at Neolithic mines in the Jizerské hory Mts. (Bohemia, Czech Republic); in addition, rock reference samples collected from the possible provenance areas and rock outcrops in the Czech Republic, Slovakia and Hungary were analysed as comparative material with the same method. We elaborated a model experience to control the thickness correction factor (TCF) following Williams-Thorpe et al. (2000).Among various stone raw materials of polished artefacts we found basaltic rocks and greenschists-metabasites as the most common.     

Marbles,granites and basalt used in the cruciform basilica of Abila (Decapolis,Jordan): archaeometric characterization and provenance

The provenance of granite, basalt, and marble used in building the cruciform basilica of Abila of the Decapolis, northwestern Jordan, is investigated using chemical and petrographic techniques. The basilica is dated to the late fifth or early sixth century AD. The stones were characterized using macroscopic traits in combination with optical microscopy, X-ray diffraction, and stable oxygen and carbon isotope spectrometry. These data were compared to the published databases for marbles, granites, and basalts used in antiquity. The comparison showed that the basalts are most probably local. The islands of Marmara (Proconessos-1), Turkey, are the primary source of the white marbles, while Paros island (Paros-2), Greece, is a minor source. The source of the green Cipollino marbles is Styra in the island of Euboea (Greece). The pink and gray granites are likely microasiatic from the Çigri and Kozak Dâgs, respectively, northwest Turkey.     

Molecular evidence of bitumen in the Mousterian lithic assemblage of Hummal (Central Syria)

Evidence for bitumen use in Middle Palaeolithic sites is an exception in Pleistocene archaeology. This paper presents the discovery of three tar-bearing Levallois artefacts found in the Mousterian sequence in Hummal (Central Syria). The organic residues were submitted to geochemical study. Gas chromatography–mass spectrometry analyses of saturated and aromatic hydrocarbons and isotopic data show the presence of bitumen. The most likely location of natural asphalt provisioning is the Shaaf outcrop in the Bichri desert. The bitumen-bearing stone tools add further important data to the growing knowledge about bitumen processing in the Middle Palaeolithic spring sites of El Kowm. Identification of the provisioning place for natural asphalt enables a more precise assumption about the site's catchment area. From a technological point of view, the tar-bearing specimens provide information on the range of tool forms selected for hafting. Ballistic features arguably indicate that the pointed Levallois blanks seem to be spear points that were fitted to a wooden handle. In at least one case, this technical procedure was seemingly executed during a brief episode of occupation and replacement of worn out implements. This small, bracketed window of detailed insight into Mousterian technology is linked with the more general relationship between Levallois technology and stone tool hafting.     

Middle Ordovician (early Dapingian) conodonts in the Central Andean Basin of NW Argentina

Carlorosi, J., Heredia, S. & Aceñolaza, G, 2013. Middle Ordovician (early Dapingian) conodonts in the Central Andean Basin of NW Argentina. Alcheringa 37, 1–13. ISSN 0311-5518.

This paper describes and analyzes the significance of a conodont fauna from the Alto del Cóndor Formation, exposed in the Los Colorados region of the Argentine Eastern Cordillera. Identified taxa are Baltoniodus triangularis, Baltoniodus sp. cf. B. triangularis, Drepanodus sp., Drepanoistodus basiovalis, Drepanoistodus sp. B., Erraticodon patu, Gothodus costulatus, Oistodus sp., Trapezognathus diprion, T. quadrangulum, Triangulodus sp. and Triangulodus? sp. The presence of Baltoniodus triangularis indicates the base of the Dapingian stage (Middle Ordovician). In addition, we report the coexistence of T. diprion and T. quadrangulum. The conodont association suggests a faunal affinity with Baltica and South China, both belonging to the Shallow-Sea Realm of the Temperate-Cold Domain.

Early Neolithic obsidians in Sardinia (Western Mediterranean): the Su Carroppu case

All the obsidians from the undisturbed Early Neolithic (Cardial ware phase I) layer of the Su Carroppu rock-shelter (Sardinia island) were studied. Their elemental composition and that of obsidians from the Monte Arci (Sardinia) volcanic complex was determined by ion beam analysis (PIXE). A comparison between the composition of Su Carroppu artefacts, analysed non-destructively, and that of Western Mediterranean analysed in the same conditions shows that the archaeological material belongs to the SA, SB2 and SC Monte Arci-types, to the exclusion of the SB1 type. The typological/technological study of this industry allowed us to reconstruct two chaînes opératoires, for the production of blades (using predominantly SC obsidians) and of flakes (based exclusively on SA and SB2 obsidians), respectively, but on the whole, assemblage blade/bladelet production was performed somewhat preferably with SA and SB2 types. Thus, in the earliest EN culture known on the island, ancient man had, for the making of its obsidian toolkit, a highly adaptive behaviour applied to the reduction of different useful obsidian sources.     

西周金文“白金”初探

1.引言 西周金文中有"白金"一词,指一种白色金属材料,但具体指何种金属材料尚待深入探究.<说文>将"银"、"鋈"和"镣"都解释为"白金也"."镣"的含义不明,可另作讨论.张子高认为在当时知识范围内只有银、锡两种白色金属,铅的颜色较暗,不入白金之列,结合考古证据,"鋈"其实是在青铜器上镀锡的工艺,释"鋈"之"白金"指锡[1].     

黑死病期间西欧的鞭笞者运动(1348—1349)

黑死病流行于西欧期间,鞭笞者运动兴盛一时。这一运动是在千禧年主义末世观的神学预设下,通过自我鞭笞来获得拯救的集体行为。在瘟疫肆虐的危机年代,鞭笞者与教会之间形成了互有分歧又彼此依存的关系。但随着运动的发展,鞭笞者反教会的色彩渐趋浓厚;更重要的是,因为瘟疫发作的时段性,以及鞭笞者宗教主张和实践效果的局限性,鞭笞者的追随者开始分化并减少。这便为教会排斥鞭笞者创造了条件。同时,鞭笞者的组织方式及其屠杀犹太人等过激行为,也对社会秩序造成了损害,从而招致了世俗政权的抵制。这样,鞭笞者运动成为众矢之的,衰退不可避免。这一运动是中世纪西欧社会 "小传统"的一种体现。以大、小传统关系变迁为视角,可以让我们更为全面地认识中世纪西欧的信仰世界。     

Reassessing the age of Atapuerca-TD6 (Spain): new paleomagnetic results

We carry out a new paleomagnetic study across stratigraphic layer TD7 of Gran Dolina Site, Atapuerca, and reassess the existing absolute ages (thermoluminescence, electron spin resonance) obtained at this site. The new and more detailed magnetostratigraphic record of the Matuyama-Brunhes boundary, combined with absolute ages, enables further constraint on the age of the underlying human-bearing level or Aurora Stratum. Paleomagnetism of the studied silts and sandstones reveals stable, dual polarity Characteristic Remanent Magnetization directions. A new normal magnetic polarity short interval is found at several consecutive sampling localities in the upper part of TD7, providing a new ante quem date for the human-bearing sediments of 0.9 Ma, possibly formed during MIS 25.

党的六大决定设立中央军事部,各地应设立军事委员会,在军事技术方面,受中央军事部指挥.1928年10月,党中央第74号指示要设立一个军事委员会,归军事部部长领导.1929年1月,中央军事委员会成立,其与中央军事部的关系未见具体说明.2月7日,共产国际执行委员会东方书记处来信严厉批评第74号指示,否定了中央军事部的构架与工作计划.8月下旬杨殷被捕牺牲,军事部部长由周恩来继任.1930年2月,军事部奉命与军委合并.中央军事部在其存在的一年半时间中,为农村革命根据地的建立及红军的发展做了许多工作,功不可没.     

Increased Sedentism in the Central Oases of the Egyptian Western Desert in the Early to Mid-Holocene: Evidence from the Peripheries

Two locations adjacent to the great central oases of the Egyptian Western Desert experienced an unusual period of sedentism in the early to mid-Holocene. Around the Southeast Basin near Dakhleh Oasis and in the Wadi el-Midauwara above Kharga, areas sharing close cultural ties, groups of slab structure sites attest to increased sedentism spanning 2,500 years. Kharga seems to have been settled fairly continuously through the two and a half millennia, but little is known of subsistence practices in this location. Dakhleh experienced two episodes of increased sedentism. Early Holocene Masara groups occupied a well-watered location within a generally dry desert. In the wetter mid-Holocene, Bashendi settlers in large stone-built sites hunted, collected wild cereals, and may have kept herds. As the desert dried after 5300 BC, the settlers switched to a life of mobile forager-herders.

西汉淮阳国(郡)辖域的变迁

西汉淮阳国封域变迁分为三个时期.高帝至景帝时为第一个时期,淮阳在郡、国之间转换频繁,封域有增有减;景帝三年至宣帝元康三年时为第二个时期,淮阳郡东界、北界不断拓展,先后得到楚国、梁国一些区域.第三个时期为宣帝重置淮阳国直到新莽时国除,此时淮阳国的封域大为削减.淮阳国所处的"中间地带"是决定其封域变迁的地理基础,而汉廷对诸...     

从近世走向近代:华北的农耕结合与村落共同体

近世以来华北农民在农耕劳动上的互助-结合行为的变化与同时代村落共同体的变迁密切相关,而对上述问题的讨论则直接关系到对该时代农村社会性质等基本问题的认识。华北农村的农耕互助具有地域特征,通过对近世华北农村的"锄社"、"合具"及近代的"搭套"、"换工"等农耕结合习惯进行考察和相互比较,可以看出华北的村落共同体经历了一个从近世走向近代的、变质的过程。
