(2006)A systematic NanoSIMS isotope imaging study of sub-micrometer phases in interplanetary dust particles (IDPs) has led to the discovery of two presolar grain types that previously were observed only in primitive meteorites. ...
-
(2006)Anions of polycarboxylic low-molecular-weight organic acids (LMWOA) compete with phosphate for sorption sites of hydrous Fe and Al oxides. To test whether the sorption of LMWOA anions decreases the accessibility of micropores ...
-
(2000)Combined cathodoluminescence (CL) and transmitted light microscopy were used to characterize quartz from flat and steeply dipping quartz veins and from veinlets in banded host rocks from the giant Muruntau Au quartz vein ...
-
(2002)The Hamitidae are a family of mid-Cretaceous heteromorph ammonites including lineages leading to four other families. Problems are outlined in trying to describe the phylogeny of completely extinct groups such as these ...
-
(2004)Cladistic analysis of the Middle Jurassic ammonite radiation shows how the Aalenian-age ancestral stock, known variously as the Hammatocerataceae or Hammatoceratinae, gave rise to numerous new groups in Bajocian times. ...
-
(2004)The uncertainty of knowledge, in contrast to that of data, can be assessed by its probability in the logical sense. The logical concept of probability has been developed since the 1930s but, to date, no complete and accepted ...
-
(1986)A chemical classification of common basalts and andesites is proposed which utilizes CIPW normative plagioclase compositions (100 an/(ab + an) = AN), differing levels of silica saturation (with respect to CIPW qz, hy, ol ...
-
(2001)Technologies of cast-in-place piles have been considered. It has been shown that the cast-in-place piles are characterized by advantages in comparison with precast piles. Classification of the cast-in-place piles has been ...
-
(2002)Deep-water sediment waves can be classified using a combination of grain size and wave-forming process, although in some cases one or other of these criteria may be indeterminable. Sediment waves are generated beneath ...
-
(1995)We have analyzed, by duplicate neutron-activation analysis, 125 members of iron meteorite groups IAB and IIICD. These data show no hiatus between the groups, and we recommend that the two sets be treated as a single group ...
-
(1989)The authors classified mantle peridotites in terms of the chemical composition of accessory chrome spinels only from harzburgites and 1herzolites containing no plagioclase. The sample of about 370 analyses includes data ...
-
(2004)A 2D seismic grid in the South Caspian Basin, offshore Azerbaijan, is used to define the areal distribution of mud volcanoes and to make a classification of the mud volcanoes based on characteristic seismic features. A ...
-
(2004)Structural geology textbooks distinguish among four end members of three-dimensional refold structures established from their two-dimensional interference patterns. Here it is shown that six different end members of ...
-
(1999)A systematic classification of the tourmaline-group minerals, general formula X Y-3 Z(6) (T6O18) (BO3)(3) V3W, is proposed, based on chemical composition and ordering at the different crystallographic sites of the tourmaline ...
-
(PANGAEA, 2019-01-24)Permafrost is an essential element of the cryosphere, which will be strongly affected by global warming. Although permafrost cannot be measured directly with remote sensing, many permafrost features are observable. ...
-
(1988)Recent data on the distribution of fluid components in rocks of various composition and origin have led to theories of evolution of fluids in endogenous processes over the course of earth's history. The data indicate that ...
-
(1996)We use a simple model of the formation, growth, coalescence and migration of veins of basaltic melt generated by partial melting in chondritic asteroids to deduce the sizes of, and pressures within, the fluid-filled dikes ...
-
(PANGAEA, 2006-07-27)The paper reports results of a study of clastic heavy mineral assemblages and geochemical features of some assemblages in several Permian-Mesozoic cherty and siliceous-clayey sequences of the Sikhote Alin Region. They are ...
-
(2004)Data from mineral magnetics, heavy mineral and quartz grain micromorphology analysis are compared, from early Pleistocene glacial sediments in the River Don palaeo-valley (central part of the Russian Plain). The aim was ...
-
(1999)Although submarine methane hydrates or clathrates have been highlighted as potential amplifiers of modern global climate change and associated glacio-eustatic sea-level rise, their potential role in sea-level fall has not ...
