Hollis, C.J, Stickley, C.E., Bijl, P.K., Schiøler, P., Clowes, C.D., Li, X, Campbell, H. March 2017. The age of the Takatika Grit, Chatham Islands, New Zealand. Alcheringa 41, xxx–xxx. ISSN 0311-5518.

The oldest Paleogene strata on Chatham Islands, east of New Zealand, are the phosphatized conglomerates and sandstones of the Takatika Grit that crops out on the northeastern coast at Tioriori and unconformably overlies the Chatham Schist. An intact Cretaceous–Paleogene boundary transition is not preserved at this locality. New biostratigraphic analysis of dinoflagellate, diatom and radiolarian microfossil assemblages confirms that the Takatika Grit is of late early–middle Paleocene (New Zealand Teurian stage) age but contains reworked microfossils of early Campanian (Early Haumurian) age. Vertebrate fossils found in this unit are inferred to be a mixture of reworked Cretaceous and in situ Paleocene bones and teeth. The overlying Tutuiri Greensand is of middle–late Paleocene age in its lower part and also contains reworked Cretaceous microfossils.

International migration into European cities has stirred a great deal of debate about appropriate national policies. But the planning literature has been remarkably silent on the issues involved, particularly as immigration affects urban conditions. This paper is a first attempt to delineate the problems and to suggest ways that planners can contribute to the economic, socio‐cultural and political integration of international migrants at the local level.  相似文献

Abstract:  The accession of the new European Union (EU) member states of Eastern Europe has highlighted ambivalence towards migration within the older member states. That same ambivalence has been less frequently discussed in the new. The former Soviet republic of Latvia serves as a case study of a new member state facing intensified pressure to accept inward migration to meet labour shortages, in part, a consequence of EU accession. Confounding appropriate political and policy responses is the sensitive issue of "ethnic balance", a troubled "legacy" of Latvian history. This has been characterised as comprising a "regime of discrimination" against the Russian-speaking minority. In the context of changes in the global migratory landscape, the potential for a renewed of regime of discrimination is emerging, based on an ethno-politics that has wider European resonance.  相似文献

Among the historical ship depictions in Eivissa (Balearic Islands, Spain), the graffiti of galleys on the Renaissance city walls are of particular interest. From archival documents the building sequences of this monument can be confirmed. Thus the galley graffiti on the eastern side of the bastion of Sant Bernat can be narrowed down chronologically to slightly after 1568. These graffiti are also interpreted from the social history point of view, in the light of ongoing corsair incursions during the 16th century.
