-
(2006)A portion of pterosaur skull from the Romualdo Member of the Santana Formation (?Albian-?Turonian, Cretaceous) of north-east Brazil provides new data on the morphology and ontogeny of azhdarchoid pterosaur cranial crests. ...
-
(2006)Pyrite bearing barite concretions are abundant in black shales of the Early Cambrian Niutitang Formation in China. Barite in these concretions exhibits greatly elevated δ34S and δ18O values, averaging 68 ± 5‰ and 20 ± 1‰, ...
-
(2006)Subfossil samples of Scots pine (Pinus sylvestris) and evidence of pine stomata and pollen accumulation rates from previously studied lakes located beyond the present pine forest line in Finnish Lapland were used to ...
-
(2006)The Load/Unload Response Ratio (LURR) method is proposed for short-to-intermediate-term earthquake prediction [Yin, X.C., Chen, X.Z., Song, Z.P., Yin, C., 1995. A New Approach to Earthquake Prediction - The Load/Unload ...
-
(2006)Although there is a continuum in magnitude of diversity loss between the smallest and largest biotic crisis, typically most authors refer to the largest five Phanerozoic events as "mass extinctions". In the past 25 years ...
-
(2006)Dikes of albitite cross-cut two massifs of serpentinized lherzolite in the Pyrénées, France. At Espéchèe (Hautes-Pyrénées), they are corundum-bearing, whereas at Urdach (Pyrénées-Atlantiques), some dikes contain corundum, ...
-
(2006)In contrast with the understanding of present-day soil erosion processes, knowledge on past soil erosion phenomena is still rather limited. Although some studies report on severe gully erosion phases during the fourteenth ...
-
(2006)The crystal structures of an anthropogenic Sn2+ silicate, Sn6O4(SiO4), hexagonal, space group P63mc, a 7.3742(4), c 11 9598(10) Å, V 563.23(6) Å3, Z = 2, Dcalc 5.12 g/cm3, and an anthropogenic Sn2+ sulfate, Sn6O4(SO4)(OH)2, ...
-
(2006)To understand the variations of organic carbon inputs in high latitude rivers, we tracked the changes in fatty acid concentrations and their stable carbon isotopic compositions in dissolved (DOM, <1 kda), colloidal (com, ...
-
(2006)The Plio-Pleistocene Trophonopsis in northern Japan consists of seven species: T. kamchatkana (Dall), T. uyemurai (Yokoyama), T. sasae Sawada, T. vermeiji Amano, sp. nov., T. aff. densicostata Golikov in Golikov and Scarlato, ...
-
(2006)Instrumental records reveal that the current rate of Arctic warming greatly exceeds mean global warming. However, Arctic temperatures during the Pliocene were considerably warmer than present, making it an excellent time ...
-
(2006)The Bulong gold deposit, located in Akqi County, Southwest Tianshan, China, occurs in Upper Devonian fine-grained clastic rocks. Gold mineralization is controlled by a series of gently tilted fractured zones. Four ore-bearing ...
-
(2006)The vibrational spectrum of Mg2SiO4 olivine was calculated at the Γ point by using the periodic ab initio CRYSTAL program. An all electron localized Gaussian-type basis set and the B3LYP Hamiltonian were employed. The full ...
-
(2006)The term glauconite covers a series of iron-rich minerals that form in the upper layer of sediments of the sea bottom in locations where sediment input is low. Because of its potassium content and the process of its ...
-
(2006)A high-resolution late-Holocene sea-level record is produced from salt-marsh deposits at Vioarhólmi in Snæfellsnes, western Iceland. The stratigraphy of Vioarhólmi saltmarsh is documented using detailed descriptions of ten ...
-
(2006)The current state of understanding of the lunar interior is the sum of nearly four decades of work and a range of exploration programs spanning that same time period. Missions of the 1960s including the Rangers, Surveyors, ...
-
(2006)Corundum xenocrysts from alkaline basalt fields differ in characteristics and hence lithospheric origins. Trace element, fluid/ melt inclusion and oxygen isotope studies on two eastern Australian corundum deposits are ...
-
(2006)The single-crystal elastic constants of natural alunite (ideally KAl3(SO4)2(OH)6) were determined by Brillouin spectroscopy. Chemical analysis by electron microprobe gave a formula KAl3(SO4)2 (OH)6. Single crystal X-ray ...
-
(2006)Based on the evaluation of 1323 carbon isotope values for Silurian to Permian terrestrial organic carbon, measured on plant fossils, cuticules, humic coals and bulk terrestrial organic matter (TOM), we conclude that the ...
-
(2006)The chromitite deposits of the Nuasahi and Sukinda massifs are part of layered ultramafic bodies which occur within Archaean low-grade metamorphic rocks of the Iron Ore Group (IOG) in the Singhbhum Craton of the Indian ...
