In the area of the Kończyce Wielkie quarry (middle-southern Poland), the Quaternary deposits of different genesis crop out. The lower fluvial series is overtopped with the glacigenic sediments occurring below the Matuyama–Brunhes boundary. This ice-sheet advance is correlated with the Günz and with the oldest traces of glaciations in Western Europe. Culture materials were located within layer of fluvial sands with fine-grained gravels, below the boulder pavement and diamicton – interpreted as till. Raw materials inventory are local flint and hornstone, also foreign flint, hornstone, quartzite, opalite and gneissose granite. The inventory contained macrolithic and microlithic cores, flakes and tools. The tools are made from pebbles, flakes and microlithic-flakes.  相似文献

秦朝末年,中原纷扰,匈奴南下与秦界于"故塞",所谓"故塞",即是战国时期修筑的秦昭襄王长城、赵武灵王长城和燕长城。汉兴之后,依然与匈奴以"故塞"为界,虽然匈奴屡屡进犯,但由于汉军的顽强抵抗和匈奴民族习性使然,西汉仍能保持这条边界,直到汉武帝元朔二年(前127年),此边界才开始向外拓展。辽东一地较为特殊,其地退守"故塞"...  相似文献

Iron I sites in the northwestern Negev were identified as Philistine on the basis of the references to Philistines in this region in the book of Genesis, its proximity to Gaza, and the occurrence of Philistine pottery. Triggered by emerging discrepancies between the finds at these sites and the presumed Philistine attributes (e.g. the rarity of pork, hearths), this article aims to reevaluate the finds in the periphery of Philistia, mainly in the northwestern Negev, but also in the Shephelah and the Yarkon basin. A systematic examination of the data reveals a clear pattern in which the population of peripheral sites gradually adopted certain Philistine attributes (Philistine pottery and cooking jugs, which were avoided during the first phase of Philistine settlement), but continued to systematically avoid others (Aegean-type hearths and significant amounts of pork), and maintained clear and sharp boundaries with the Philistine centers. A thorough examination of the data suggests that most of the inhabitants in the periphery of Philistia were the descendants of the local Canaanite population of the Late Bronze Age, who were in the process of renegotiating their identity with the emerging ethnicities of the Philistines in the urban centers of the southern coastal plain and the Israelites farther west. While not forming a unified group, and probably being politically dominated by Philistia, the inhabitants of the settlements in the periphery of Philistia did not adopt a Philistine identity, maintained clear boundaries with the Philistines, and should not be treated as Philistines.  相似文献

Slimani, H., Louwye, S. & Toufiq, A., September 2012. New species of organic-walled dinoflagellate cysts from the Maastrichtian–Danian boundary interval at Ouled Haddou, northern Morocco. Alcheringa 36, 341–358. ISSN 0311-5518.

Seven new dinoflagellate cyst species and subspecies, previously figured under open nomenclature, from Maastrichtian and Danian deposits of Ouled Haddou (eastern external Rif Chain) in northern Morocco are formally described, and their stratigraphic ranges are clarified. Conosphaeridium lifum sp. nov. and Kenleyia chabaka sp. nov. have fibrous and reticulate wall surfaces, respectively. Oligosphaeridium saghirum sp. nov. is a small cyst with funnel-shaped distal process extremities. Spiniferella cornuta subsp. kacira subsp. nov. and Fibrocysta brevispinosa sp. nov. are distinguishable by their very short processes. Riculacysta chaouka sp. nov. is characterized by its perforate spinose ectophragm. Andalusiella bacita sp. nov. is a small and spindle-shaped cyst with only a single antapical horn.  相似文献

It is well known from nature and experiments that the presence of brine strongly affects the microstructural evolution and the mechanical and transport properties of halite. Existing interpretations of the grain boundary structure in deformed, wet, salt samples annealed statically at room temperature are based on indirect evidence from reflected light microscopy and conventional scanning electron microscopy. This paper presents direct observations of fluid‐filled grain boundaries using the cryogenic‐scanning electron microscope (cryo‐SEM) in which the grain boundary fluids were frozen before breaking the samples. The rapid cooling transforms the brine into two phases, i.e. ice and hydrohalite, which are easily recognized from characteristic segregation patterns. We studied samples of wet, synthetic, polycrystalline halite annealed under static conditions at room temperature. In coarse‐grained samples, fine‐scale segregation patterns were observed at the boundaries of the primary recrystallizing grains. These points indicate the existence of fluid films with a thickness in the range of 30 nm, but the finer scale structure of the fluid remains unknown. In fine‐grained samples, the distribution and reorganization of fluids with annealing time is recorded by the combination of contact healing and successive accumulation of fluids in triple junction tubes. The contact healing is attributed to the small initial grain size, such that the fluid film necks down by accumulating the fluids into previously existing triple junctions via neck growth. Electron backscatter diffraction measurements of both primary and secondary recrystallized grains indicate that they are euhedral, i.e. the grain growth morphology is controlled by the anisotropy of the grain boundary energy of the growing grain, which results in planar growth faces.  相似文献

13~18世纪云贵川交界地区政区设置变化趋势研究   总被引:1,自引:0,他引:1  
13-18世纪金沙江以东的云、贵、川交界地区在政区设置上产生了一系列变化,主要变化趋势表现在:在政区层级上,由繁而简;在基层政区设置的空间过程上,由外而内;在政区的实际控制上,由虚到实。这一时期本地区地方部族力量的不断减弱与中央权力的逐渐加强是导致这些变化趋势的主要原因。  相似文献

How does political structure affect ethno‐national distinction? Partitioned societies are a good test case where we can see the effects of changed socio‐political circumstances on historically inherited distinction. This article takes nominally identical distinctions of nationality and religion with common historical roots and shows how they are differentially understood in two polities partitioned in 1920: Northern Ireland, a devolved region of the United Kingdom, and the Irish state. Using a data base of interviews with over 220 respondents, of which 75 in Northern Ireland, conducted between 2003 and 2006, it shows how complex, potentially totalising and exclusive ‘ethnic’ and ‘ethno‐national’ divisions are built up from simpler and more permeable distinctions. Respondents interrelate the same elements into a loosely‐knit symbolic structure – different in each jurisdiction – which frames expectations and discourse, and which is associated with different logics of national discourse, one focussing on personal orientation, the other on group belonging. The resultant ‘ethno‐national’ distinctions function differently North and South.  相似文献

The 1992–1993 civil wars in Moldova and in Georgia ended with a de facto separation of Transnistria and Abkhazia, respectively. These de facto states are both inhabited by the kin to the ‘enemy’ across the administrative border: Moldovans and Georgians/Mingrelians. How do the de facto authorities foster a collective identity in support of their claim for legitimacy and statehood? Engaging with Wimmer's taxonomy of boundary‐making, this article argues that nation‐building involves not only expansion but also, simultaneously, contraction. Transnistria constructs a higher‐level identity category and co‐opts and contracts the Moldovan category, separating it into ‘our’ and Bessarabian Moldovans in order to incorporate the former into the Transnistrian people. In Abkhazia, the nation‐building project establishes the Abkhazs as the titular nation allowing, however, for the construction of an Abkhazian people that would include minorities, with Gal/i Georgians said to be Mingrelians, distinct from Georgians. These cases show that elites combine different ethnic boundary‐making strategies in order to implement their favoured identity project and to legitimize the claimed statehood.  相似文献
