-
(2004)In an early attempt to incorporate infraspecific, varietal categories into conventional, morphodescriptive Linnaean taxonomy, Quenstedt in 1845 introduced an idiosyncratic trinominal nomenclature that has bedevilled ammonite ...
-
(2002)Polycrystals undergoing ductile deformation develop lattice-preferred orientation (fabric) as a result of intracrystalline slip. A consequence of fabric development is that bulk physical properties become anisotropic. ...
-
(2006)The main hole of the Chinese Continental Scientific Drilling Project (CCSD-MH) is located in the Maobei eclogite complex, south Sulu UHP terrane. Eclogites from 0 ~ 600m in depth of the CCSD-MH are characterized by ...
-
(2002)A practical and reliable method for the preparation of fine-grained forsterite and forsterite-enstatite polycrystals, in the system MgO-SiO2s described. The method employs state-of-the-art techniques from materials science, ...
-
(1999)Detailed analysis of the crystal structures of minerals and inorganic compounds containing oxocentred [OCu 4 ] tetrahedra reveals the following principle for relationships between oxocentred tetrahedra and tetrahedral ...
-
(2006)Tengiz field is an isolated carbonate buildup in the southeastern Precaspian Basin, containing a succession of shallow-water platforms ranging in age from late Famennian to early Bashkirian. Platform backstepping from ...
-
(1996)Neoproterozoic–Cambrian rocks of the Zavkhan Basin (Govi-Altay, western Mongolia) comprise large-scale alternations of siliciclastic- and carbonate-dominated units (cf. ‘Grand Cycles’). Analysis of such depositional sequences ...
-
(2006)The volcanic island of Milos, Greece, comprises an Upper Pliocene –Pleistocene, thick (up to 700 m), compositionally and texturally diverse succession of calc-alkaline, volcanic, and sedimentary rocks that record a transition ...
-
FACIES DIFFERENTIATION OF MINERAL AND ORGANIC MATTERS UNDER COASTAL-MARINE SEDIMENTATION CONDITIONS (2004)Coastal-marine sedimentation conditions in the Pechora River delta, Korovinskaya Bay, and intertidal zone of the Pechora Sea are characterized by diverse physicochemical processes that define the differentiation of mineral ...
-
(1988)A characteristic feature of shallow granitoid rocks is graphic quartz-feldspar intergrowths, which are superb examples of a crystallized eutectic. The quartz content of these regular intergrowths is a sensitive indicator ...
-
(2006)Twenty-two sediment cores raised from the central and eastern parts of the Barents Sea have been studied to reconstruct the evolution of the facies system since the Late Weichselian glaciation. Multiproxy records reveal ...
-
(2006)Large submarine canyons incise most continental margins, but outcrops of comparably sized ancient examples are relatively rare. A preserved cross section of a filled Cretaceous-Paleocene submarine canyon, tens of kilometers ...
-
FACILITATION OF BARIUM UPTAKE INTO FISH OTOLITHS: INFLUENCE OF STRONTIUM CONCENTRATION AND SALINITY (2005)To reconstruct patterns of fish migration using otolith chemistry, it is essential to validate the relationship between elements in otoliths and the surrounding water, and in particular, how processes such as competition ...
-
(1995)Quadrupole mass spectrometric (QMS) analysis of small amounts of inclusion fluid (<1 milligram) released by crushing and decrepitation requires methods to: (1) determine the amount of molecular fragmentation relative ...
-
(2001)Sediment sorption capacity was measured in a coastal environment over a 2-year period using lysine as a model compound. Sorption capacity was found to vary over time but did not seem to follow a clear seasonal pattern or ...
-
(2001)The effect of magnetic interactions has been commonly neglected in the interpretation of the anisotropy of magnetic susceptibility (AMS) of igneous rocks, despite the likely occurrence of magnetic interactions due to their ...
-
(2002)A geochemical study of Cryogenian (late Neoproterozoic) limestones from western Mongolia is presented, including δ13C (carbonate and kerogen), δ18O, 87Sr/86Sr and rare earth element data. Carbon isotope compositions confirm ...
-
(2001)Compositions of ∼2500 spinel–olivine pairs and 400 melt inclusion–spinel pairs have been analysed from 36 igneous suites from oceanic, arc and intraplate tectonic settings. Our data confirm that Cr-spinel mg -number is ...
-
(2003)During their deceleration through the Earth's atmosphere, meteoritic materials, i.e., interplanetary dust particles, micrometeorites and meteorites, experience thermal shocks which may alter their pristine mineralogy, ...
