(2002)Phyllosilicates produced mostly by weathering of magmatic, metamorphic and sedimentary rocks are widespread in the surficial and near-surface zones of the Earth’s crust. These phyllosilicates display very fine grain sizes, ...
-
(2002)The history of the study and the development of ideas about the systematic position of the Cambrian univalved mollusks is reviewed. On the basis of the functional morphology of shells (Parkhaev, 2000a, 2001a), the phylogenetic ...
-
(2002)Biogeography played an important role in early developments in evolutionary theory and continues to play an important role in evolutionary studies and paleogeographic reconstructions. The development of a phylogenetic ...
-
(2004)Phylogenetic analysis of the Early and early Middle Ordovician (Tremadoc and Arenig) ostracod species of Baltoscandia suggests a polyphyletic origin for the suborder Beyrichiocopa. Binodicopes, leiocopes and eridostracans ...
-
(2003)The methods of phylogenetic studies are legitimate and supplement each other. However, even taken as a whole, they cannot provide a complete reconstruction of the course of evolution.
-
(2001)We present a synopsis of high-rank multituberculate systematicsand a manually generated cladogram illustrating multituberculate interrelationships. We divide the Multituberculata into the paraphyletic suborder ‘Plagiaulacida’, ...
-
(2004)Phylogenetic analysis reveals that the Triassic diapsid family Drepanosauridae is closely related to Coelurosauravus and Longisquama. These three taxa are part of a clade for which the name Avicephala (defined as all taxa ...
-
(2004)A phylogenetic analysis of 36 species provides a test for the taxonomy and the history of Early Cretaceous spatangoids. Most taxonomic units from genera to suborders are consistent with the proposed phylogenetic framework. ...
-
(2001)Laboratory determinations of compressional wave velocity, porosity, density and sediment texture have been conducted on samples collected from the inner shelf Holocene mud sediment in the South Sea and southern part of the ...
-
(2004)Epidote minerals are known since the 18th century, but at that time the greenish to dark colored varieties were termed actinolite or schorl and not distinguished from the minerals to which these names apply today. Haüy defi ...
-
(2002)The relationships between electrical conductivity, temperature, salinity, and density are studied for brackish Lake Issyk-Kul. These studies are based on a newly determined major ion composition, which for the open lake ...
-
(1998)The chemical composition of Niger river water measured bimonthly at Bamako (Mali) during the period 1990-1992 provides an estimate of present weathering rates in the upper Niger basin. The dominant weathering process is ...
-
(1992)The composition and structural features of megacrystals of garnets, ilmenites, monoclinic pyroxenes, K-Na-feldspars occurring as inclusions in the Cenozoic alkaline basalts of Mongolia have been studied by means of X-ray ...
-
(1988)Zones of active orogeny with rapid and irregular movements (e.g. the Alpine Himalaya belt) and a zone of slow movements (East European and Siberian platforms) are differentiated in two sets of precise levelling data. A ...
-
(2004)We study the dynamic traction and the slip velocity evolution within the cohesive zone during the propagation of a dynamic rupture using rate- and state-dependent constitutive laws. We solve the elastodynamic equation for ...
-
(1989)Several geodynamic situations involve strong horizontal compression of the lithosphere that produces a high degree of its deformation or failure. This is especially true of active continental margins, collision zones, and ...
-
(2000)The effects of surface resistivity inhomogeneities on magnetotelluric sounding (MTS) curves under the complex geologic conditions of the Site were examined. Three-dimensional models were used to imitate a resistivity ...
-
(2004)This paper presents results of shear strength and acoustic velocity (p-wave) measurements performed on: (1) samples containing natural gas hydrate from the Mallik 2L-38 well, Mackenzie Delta, Northwest Territories; (2) ...
-
(1996)Relationship between physical property change of melt and solidification structure has been investigated by measuring the density, viscosity and electrical resistivity of the Al-Si eutectic alloy melt with different Ce ...
