(2006)To test existing models for the formation of the Amerasian Basin, detrital zircon suites from 12 samples of Triassic sandstone from the circum-Arctic region were dated by laser ablation-inductively coupled plasma-mass ...
-
(2006)The association of isolated remains of lobopods with a netlike structure, including plates of Microdictyon rozanovi sp. nov. and sclerites with spinelike process of Onychomicrodictyon spiniferum gen. et sp. nov., as well ...
-
(2006)A complete well-preserved male fly from the Jurassic of Daohugou locality (Northeastern China) is described as Proptychopterina opinata sp. nov. The distribution of Proptychopterina is discussed, this genus is re-diagnosed, ...
-
(2006)The position of attachment of the shell muscle is discovered in the columellar area of the shell of the Early Cambrian univalved genus Aldanella (family Aldanellidae, order Pelagielliformes, subclass Archaeobranchia), the ...
-
(2006)The autonomous (massif-type) anorthosite massifs of the Kalar Complex (2623 ± 23 Ma) intrude high-grade metamorphic rocks of the Kurulta tectonic block at the junction of the Aldan and Dzhugdzhur-Stanovoi fold area. These ...
-
(2006)A previously unknown type of ontogeny is discussed that unites features of two different types of loop development: the ancient dielasmoid type, which is typical of Upper Paleozoic terebratulids, and the angustothyridid ...
-
(2006)The wide distribution of the genus Ammosiphonia in the Upper Jurassic and Carboniferous of Western Siberia is established for the first time. Six haplophragmoidid species of Western Siberia are assigned to this genus. The ...
-
(2006)Two gastropod assemblages from the Lower Callovian of the Kostroma Region and the Middle Callovian of the Yaroslavl' Region are studied and compared with synchronous assemblages of the Kostroma, Moscow, Bryansk, and Kursk ...
-
(2006)Three new species, attributed to the extinct family Xyelydidae of the Pamphilioidea (Order Vespida = Hymenoptera), are described from the Middle Jurassic of Daohugou, Inner Mongolia, China: Ferganolyda scylla sp. nov., F. ...

(2006)The 40Ar/39Ar method with stepwise heating was used to date phengite and glaucophane in the contact zone of garnet glaucophanite an omphacite-garnet rock (eclogite) from the lower unit of the Maksyutov metamorphic complex. ...
-
(2006)Combined X-ray powder diffraction, Mössbauer, and XANES spectroscopy in situ experiments revealed the transformation of cubic (Mg0.8Fe0.2)O ferropericlase to a rhombohedrally distorted phase at 35(1) GPa and room temperature. ...

LATE-HOLOCENE ENVIRONMENTAL HISTORY OF TWO NEW ENGLAND PONDS: NATURAL DYNAMICS VERSUS HUMAN IMPACTS (2006)Analyses of sedimentary diatoms in two New England ponds reveal limnological changes during the past 2500 years that are related to climatic change, anthropogenic activities and natural disturbance. Deforestation in the ...
-
(2006)Research was conducted in valleys of sinuous rivers that drain medium-high mountain, foreland basin and upland areas, where loose Quaternary deposits predominate. The cyclic pattern determined for deposits of the oxbow ...
-
(2006)Two sediment cores recovered in the central part of Daihai Lake in north-central China were analysed at 2-to 4-cm intervals for total inorganic and organic carbon (TIC and TOC) concentrations. The TIC concentration is ...
-
(2006)Holocene sea-level observations have been obtained from the Ako Plain in western Japan. In this coastal area, the Holocene crustal movements have been evaluated, except the crustal response due to the last deglaciation, ...
-
(2006)Holocene molluscan and foraminiferal faunas, sensitive ecological markers, are statistically treated to define their temporal and spatial distributions in radiocarbon-dated cores in Alexandria’s Eastern Harbour. Up-core ...
-
(2006)The relationship between vegetation and surface pollen deposition is examined at Storbreen glacier foreland where a clear plant succession exists. The aim is to determine whether the distinct plant communities present ...
-
(2006)Continuous sediment, charcoal and pollen records were developed from a-4.5 m sediment core from Little Molas Lake (LML), 3370 m elevation, San Juan County, CO. LML formed by 11 200 cal. BP subsequent to glacial retreat. ...
