-
(2006)Neutron irradiation and post-irradiation annealing under oxidising and reducing conditions have been used to investigate H incorporation in, and the optical properties of, reduced (TiO2-x) rutile. Optical absorption in ...
-
(2006)Cerebavis cenomanica gen. et sp. nov. from the Middle Cenomanian of the Volgograd Region (Russia) is described based on a brain mold. The brain of Cerebavis is characterized by a mosaic combination of primitive and advanced ...
-
(2006)The distribution of spores and pollen grains was studied in nine sections of bottom sediments up to 50 m thick, in the southern Barents Sea. The Early Cretaceous, Pleistocene, and Holocene ages of the enclosing sediments ...
-
(2006)A fragmentary coracoid of Ornithomimidae indet. from the Lower Cenomanian of the Abshir River (Kyrgyzstan) is described. This is the first record of this group in a Cenomanian locality of Fergana. The coracoid from the ...
-
(2006)The role of bacteria in sedimentation of phosphorites, siliceous and carbonate rocks is discussed. Preservation of bacterial bodies in fossil condition, even in very ancient deposits, is connected with their very early ...
-
(2006)Juvenile development of the Middle Cambrian agnostid trilobite Pentagnostus proanabarensis Fedoseev, 1999 is studied. A sequence of eight juvenile stages is defined based on changes in morphology and measurements. Three ...

-
(2006)The K-Ar method and its modifications play a unique role in the geochronology of young volcanic rocks, which has important fundamental and economic aspects. This method provides an opportunity for dating Quaternary rocks, ...
-
(2006)The further development of electrodynamic model of strong DC electric field formation in the ionosphere above typhoon and earthquake regions has been presented. According to this model, the external electric current works ...
-
(2006)Since 1996, the electric field strength of the broadcasting station CZE (Czech Republic, f = 270 kHz) has been sampled each ten minutes, by a receiver (AS) located in central Italy, 818 km far from the transmitter. Here, ...
-
(2006)Pakhomovskyite, Co3(PO4)2 •8H2O, is a new mineral species found in dolomite carbonatite cutting phoscorites in the Iron-Ore Complex, Kovdor, Kola Peninsula, Russia. The mineral was found as groups (up to 3 × 2 cm) of small ...
