-
(2006)This Chapter is an introduction to the various length scales of internal stresses, the causes of internal stresses and in particular their measurement by neutron diffraction. Some of the approaches used to model and interpret ...
-
(2006)The predominantly migmatitic Palaeoproterozoic Uusimaa belt preserves early lower-grade Svecofennian structures in the Orijärvi area in SW Finland. This study aims at explaining the deformational history responsible for ...
-
(2006)The crystal structures of natural Ag-free lillianite of fumarolic origin from Vulcano, Aeolian Islands, Italy, Pb2.88 Bi2.12 (S5.67Se0.33) ∑6.00, with a 13.567(1), b 20.655(2), c 4.1216(4) Å, V 1155.0(2) Å3, space group ...
-
(2006)The metal sulfides exhibit a great diversity of electrical and magnetic properties with both scientifi c interest and practical applications. These properties apply major constraints on models of the electronic structure ...
-
(2006)Data from Late Cretaceous paleoclimate simulations and their linkage to a geological model derived from long-term high-resolution proxy-data indicate and support strong relationships between African climate and tropical ...
-
(2006)The fulfillment of a scaling law for earthquake recurrence-time distributions is a clear indication of the importance of correlations in the structure of seismicity. In order to characterize these correlations we measure ...
-
(2006)A loess-paleosol sequence and a lake sediment record from the central Hexi Corridor in the drylands of NW China show patterns of persistent millennial- to centennial-scale climate variability during the Holocene epoch, ...
-
(2006)The origin of water is a long standing problem that has fascinated generations of philo-sophers and scientists since the dawn of humanity. It has to do with processes that took place in the ...
-
(2006)Testate amoebae are valuable indicators of peatland hydrology and have been used in many palaeoclimatic studies in peatlands. Because the species' ecological optima may vary around the globe, the development of transfer ...
-
(2006)The Aral Sea Basin is a critical area for studying the influence of climate and anthropogenic impact on the development of hydrographic conditions in an endorheic basin. We present organic-walled dinoflagellate cyst analyses ...
-
(2006)Grasses (Poaceae) are distributed across the world in broad latitudinal belts and are an important source of C4 biomass in the geological record of soils as well as lake and marine sediments. We examined long-chain leaf ...
-
(2006)The Sânpetru Formation (Haţeg Basin, Romania) was deposited in an active extensional basin in response to the post-orogenic collapse of the Southern Carpathians. Despite being one of the best exposed latest Cretaceous ...
-
(2006)Middle Neoproterozoic carbonates are found in the western part of Shandong Pennisula (i.e., the Jiaobei terrane) that is located in the northwestern part of the Sulu orogen in east-central China. For the first time, a ...
-
(2006)Water plays a dominant role in many glacial processes and the erosional, depositional and climatic significance of meltwaters and associated fluvioglacial processes cannot be overemphasized. At its maximum extent c. 20,000 ...
-
(2006)An understanding of chemical bonding and electronic structure in sulfide minerals is central to any attempt at understanding their crystal structures, stabilities and physical properties. It is also an essential precursor ...
-
(2006)Oman records in its Neoproterozoic Nafun Group (Huqf Supergroup) an essentially complete, carbonate-rich Ediacaran succession. The Nafun Group overlies the presumed Marinoan rift-related Fiq Member (ca. 635 Ma) and ends ...
-
(2006)Spectroscopic methods are the most direct and powerful means of obtaining experimental information on the electronic structures of materials. They also provide crucial information on aspects of crystal structure, crystal ...
-
(2006)Sediment cores recovered from three mid-arctic lakes on Cumberland Peninsula, eastern Baffin Island, Arctic Canada, contained two units of unconformably superimposed organic sediment (gyttja), the upper of which represented ...
-
(2006)This paper describes our recent extraction of ancient DNA (aDNA) from Holocene pollen and discusses the potential of the technique for elucidating timescales of evolutionary change. We show that plastid DNA is recoverable ...
-
(2006)Stable isotope data of mollusc shells from two adjacent time slices (Karpatian/Badenian) from the Central Paratethys were investigated to detect differences in environmental parameters and to depict shifts in the isotope ...
