Numerous plutons composed of granite, granodiorite, diorite-porphyry, monzonite, granodiorite-porphyry and diorite/microdiorite-porphyry occur at the boundary of the TavêanlÏ-Sakarya Zone, in the eastern part of the northwestern Anatolian magmatic belt, Turkey. These rocks belong to two different types: a medium-K calc-alkaline granodiorite series (with associated dykes and sub-volcanic rocks) and a shoshonitic series of granites. The rocks of the shoshonitic series have SiO₂from 67.5 to 75.6 wt.% with Mg# from 35.1 to 59.5, whereas the medium-K calc-alkaline series rocks have SiO₂ between 54.6 and 67.7 wt.% with Mg# from 43.5 to 60.8. There is a clear enrichment of LILE with respect to the HFSE in all magmatic units of the region. These magmatic rocks reflect properties of collision-related arc magmatism in the various geochemical discrimination diagrams. The initial Sr/⁸⁶Sr and ¹⁴³Nd/¹⁴⁴Nd istopic ratios of the magmatic units range from 0.705506 to 0.710902 and 0.512178 to 0.512594, respectively. Collision-related granitoids yielded a ⁴⁰Ar/³⁹Ar cooling age age of 59.13 ±1.87 Ma, and arc-related granitoids and associated sub-volcanic units 44.3 ±0.47 and 44.11 ±0.89 Ma. The data obtained revealed that continent-continent collision in the Paleocene together with the initiation of the closure of the Neo-Tethys took place between the Anatolide-Tauride Platform and Sakarya Plate from the end of the Cretaceous. The shoshonotic granite may cooled in the Middle Paleocene, as regards the subduction-accretion zone in which subduction impacts have been observed. The medium-K calc-alkaline magmatic products in the region were formed by partial melting of the continental lithospheric mantle caused by the upwelling of asthenospheric mantle after the subducted slab was delaminated.

Artykuł powstał na podstawie analizy ról polskich matek w kontekście zmian społecznych, w których uczestniczyły rodziny polskie w związku z ich deportacją w głąb Związku Radzieckiego w 1940 roku. Autorki zaprezentowały życie deportowanych osób w kontekście procesów kreowania enklaw społecznych, ze szczególnym uwzględnieniem sposobów, w jaki zesłańcy kształtowali na nowo środowiska społeczne. Z uwagi na fakt, że środowiska te były pod pewnymi względami odseparowane od szerszego społeczeństwa,można stwierdzić, że zesłańcy uczestniczyli w kształtowaniu enklaw. Główne pytanie, na jakie odpowiedziano w artykule, brzmi: „W jakim sensie życie osób zesłanych w głąb ZSRR naznaczone było (lub jest) enklawowością?”. Odpowiadając na to pytanie, autorki zwracają uwagę na napięcie istniejące między procesem przystosowywania się do nowego środowiska (proces inkluzji) a modyfikacją i zarzucaniem pewnych wartości i norm (proces ekskluzji). Autorki opisują procesy utrzymywania tradycyjnych wzorów kulturowych, wartości i norm społecznych z czasów przed zesłaniem oraz koniecznością ich adaptacji do nowych warunków zastanych w miejscu zesłania.

The text is based on the former analysis of Polish women’s activities in the context of social changes in the aftermath of being deported deep into the Soviet Union in the 1940s. More specifically, the paper presents deportees’ life as a process of creating social enclaves. We describe the way the exiled were forced to shape new social environments, separated in some respects, namely – the enclaves. The main question is: In which way were the lives of Poles exiled to the USSR during the WW II marked and shaped by the process of creating enclaves? The tension between tendencies displayed while adjusting to the new environment (inclusion) and the process of challenging some values and norms (exclusion) are pointed out. In the paper, the process of maintaining the ties reaching back to the times prior to the exile and the necessity of adapting old norms, values and cultural factors to the new context of deportation are also explained. The text is chronologically ordered and opens with the description of first arrests and transportations. Arrests, transportation to the USSR, living in exile and coming back to Poland are described. Some aspects of functioning of former deportees in the present are also addressed. The lives of deportees during the exile and after it as well created a kind of a different social world , which had features of enclaves.

Many granitic intrusions display evidence of magma mixing processes. The interaction of melts of contrasting composition may play a significant role during their generation and evolution. The Strzegom-Sobótka massif (SSM), located in the Sudetes (SW Poland) in the north-eastern part of the Bohemian Massif of the Central European Variscides, exhibits significant evidence of magma mingling on the macro- and micro-scales. The massif is a composite intrusion, with four main varieties: hornblende-biotite granite (with negligible amount of hornblende) and biotite granite in the western part, and two-mica granite and biotite granodiorite in the eastern part. Field evidence for magma mingling is easily found in the biotite granodiorite, where dark enclaves with tonalitic composition occur. Enclaves range from a few centimeters to half a meter in size, and from ellipsoidal to rounded in shape. They occur individually and in homogeneous swarms. The mixing textures in the enclaves include fine-grained texture, acicular apatite, rounded plagioclase xenocrysts, ocellar quartz and blade-shaped biotite. The most interesting feature of the enclaves is the presence of numerous monazite-(Ce) crystals, including unusually large crystals (up to 500 μm) which have grown close to the boundaries between granodiorite and enclaves. The crystallization of numerous monazite grains may therefore be another, previously undescribed, form of textural evidence for interaction between two contrasting magmas. The textures and microtextures may indicate that the enclaves represent globules of hybrid magma formed by mingling with a more felsic host melt. Chemical dating of the monazite yielded an age of 297±11 Ma.

W artykule najpierw przywołano rozważania dotyczące enklaw, które mogą być oceniane pozytywnie – czyli takich, które są rodzajem „zamknięcia przed”. Następnie przypomniano najważniejsze sprawy dotyczące rozumienia kultury masowej, internetu oraz innych elektronicznych urządzeń współtworzących dzisiejszą kulturę medialną. Przede wszystkim jednak rozważany jest problem, czy w cywilizacji współczesnej, choćby potencjalnie, możliwe jest pełne odizolowanie się od tej medialnej kultury. W konkluzji stwierdzono, że niestety taka izolacja, gdyby miała być pełna i konsekwentna, praktycznie nie jest możliwa.

The article begins with considerations concerning enclaves that may be positively valued: those that are a sort of “closing off”. Then, the main issues concerning the understanding of the mass culture, the Internet and other electronic devices co-creating the contemporary media culture will be discussed. Above all, we will concentrate on the problem of whether an isolation from the media culture is potentially possible in the contemporary civilization. We conclude that, unfortunately, this sort of full and consistent isolation is practically not possible.

Public spaces are substantial to urban landscape. Usually when specifying their types squares and streets are mentioned. But when the lines and figures become present in the third dimension they often represent terraces and stairways. The purpose they serve in urban design may differ from the stairway communicating city districts through terracing square concentrating urban tissue to a composition accenting the void substituting buildings. Whether the shape was inspired by natural topography or purely abstract concept since the antiquity steps were used as an element in urban planning. Nowadays the meaning of stairs has not diminished; it is constantly changing following the evolution of contemporary city.

PL

Przedmiotem analizy jest obóz dla oficerów Oflag II C Woldenberg, jako enklawa i eksklawa wojenna z lat 1939–1945. Woldenberg to obecnie Dobiegniew w województwie lubuskim. Obozy jenieckie tworzone przez niemieckich nadzorców z Wehrmachtu to przykłady eksklaw, nastawionych na izolację w złych warunkach tysięcy żołnierzy i oficerów oraz wykluczenie ich z normalnego życia. Organizacja życia jeńców wewnątrz świata podwładnych, zwłaszcza działalność kulturalna, edukacyjna, sportowa to przykłady tworzenia enklaw umożliwiających przetrwanie. W artykule skoncentrowano się na studium przypadku Oflagu II C Woldenberg (w tym zwłaszcza enklawie sportowej). Problematykę obozową przedstawiono przy użyciu pojęć eksklaw i enklaw, prowadząc do skonstruowania typologii: enklaw/eksklaw przestrzennych, funkcjonalnych, statusowych, repertuarowych oraz wielorakich enklaw/eksklaw sportowych (związanych z dyscyplinami sportowymi, klubami, rolami zawodników, amatorów, kibiców, instruktorów, władz obozowych, wydarzeniami sportowymi i zajęciami w-f). Artykuł stanowi studium z pogranicza historii i socjologii (socjologii kultury i socjologii sportu), zmierzające do wykazania przydatności pojęć enklaw i eksklaw do analizy świata społecznego oflagu – obozu; a także przykład pewnej „gry socjologicznej”.

EN

The subject of the analysis is the camp for officers Oflag II C Woldenberg as an enclave and war enclave in the years 1939-1945. The current name of Woldenberg is Dobiegniew in the Lubuskie province (woivodeship). Prisoners of war camps founded by the German Wermacht wardens were an example of enclaves the aim of which was to isolate thousands of soldiers and officers in very bad conditions and exclude them from normal life. The organization of life of the prisoners of war within the world of subordinates, primarily their cultural, educational and sports activities, were examples of enclaves which made it possible for them to survive. The article focuses on the case study of Oflag II C Woldenberg, particularly on its sports enclave. The question of the camp has been presented by employing the concepts of exclaves and enclaves leading to constructing the following typology: enclaves/exclaves – spatial, functional, based on status or repertoire and other multiple sports enclaves/exclaves relevant to sports disciplines, clubs, roles of contestants, amateurs, instructors, coaches, fans, camp authorities, sports events and physical exercises. The study is on the borderline between a historical and a sociological approach (sociology of culture and sociology of sport) attempting to show the usefulness of the concepts of enclaves and exclaves in the analysis of the Oflag- camp social world. It is also an example of a ‘sociological game’.
