(2006)The soils of the Atacama Desert in northern Chile have long been known to contain large quantities of unusual salts, yet the processes that form these soils are not yet fully understood. We examined the morphology and ...
-
(2006)Boron is an important micronutrient for plants but is toxic at high pore solution concentrations. Its mobility and migration in many geochemical environments is often controlled by reactions with mineral surfaces, and thus ...
-
(2006)Pull-off forces were measured between a silica colloid attached to an atomic force microscope (AFM) cantilever and three homopolymer surfaces representing constituents of extracellular polymeric substances (EPS). The ...
-
(2006)Alkaline igneous rocks of the Crowsnest Formation in southwestern Alberta and in the Howell Creek area in southeastern British Columbia have been suggested previously to be cogenetic. To test this hypothesis, samples of ...

CLIMATE AND VEGETATION CHANGES 180,000 TO 345,000 YEARS AGO RECORDED IN A DEEP-SEA CORE OFF PORTUGAL (2006)A new high-resolution combined marine proxy-pollen sequence from the Portuguese margin, MD01-2443, enables direct comparison of ocean and ice volume changes with vegetation development in south-west Iberia during marine ...
-
(2006)Production rates of cosmogenic nuclides at the earth's surface are controlled by the intensity of energetic cosmic-ray nucleons, which changes rapidly with elevation. An incomplete knowledge of how nucleon fluxes vary with ...
-
(2006)The speciation and thermodynamic properties of ferric chloride complexes in hydrothermal solutions and hypersaline brines are still poorly understood, despite the importance of this element as a micronutrient and ore-component. ...
-
(2006)Magmatism in the Gardar Province, South Greenland, is related to two main rifting events at 1280 Ma and 1180 to 1140 Ma. Little is known about the duration of the magmatic activity in a specific complex. The Ilímaussaq ...
-
(2006)This paper aims to illustrate and discuss mechanism(s) responsible for the growth and evolution of large-scale corrugated normal faults in southwest Turkey. We report spectacular exposures of normal fault surfaces as parts ...
-
(2006)Based on the agreement between geodetic and geological plate velocities, interplate fault slip rates are usually considered constant over long periods of time. However, measurements made at different time scales on ...
-
(2006)The submerged portions of the North Anatolia Fault system beneath the Marmara Sea were studied with high-resolution multibeam bathymetry, subbottom profiling and sediment cores. The major objectives were to learn about the ...
-
(2006)Two models, derived in very different ways but both incorporating the symmetry constraints outlined in the previous paper, are developed for use in simulating Thellier-type palaeointensity experiments. These are then tested ...
-
(2006)In this paper, we discuss the possibility that the North Anatolian fault (NAF) results from the deep deformation of the slab beneath the Bitlis-Hellenic subduction zone. We described the tectonic evolution of the Anatolia-Aegean ...
-
(2006)In this paper, we have examined carbon and nitrogen isotopic compositions in two ornithogenic sediment profiles from the Ardley Island and Barton Peninsula of Antarctica for palaeoecological changes during the past 2000 ...
-
(2006)This paper presents multi-species records of the Li/Ca ratio and Li isotopic composition (δ7Li) of planktonic foraminifera from the Pacific and Atlantic oceans for the past 18 Ma. The Li/Ca record is corrected for interspecific ...
-
(2006)Analysis of available data indicates that different values of the Curie temperature for magnetite and titanomagnetites along with transition between ferric (Fe III) and ferrous (Fe II) iron could lead to significant errors ...
-
(2006)Since its inception in the late 1970s, accelerator mass spectrometry has become a powerful tool for measurement of trace amounts of natural radionuclides. In this paper, we review recent advancements in AMS and discuss ...
-
(2006)We investigated the thermal decomposition of muscovite in natural granite powders heated to 1175 °C for durations from 5 min to 69 h, at 1 bar, paying special attention to the early stages of decomposition. This study shows ...
-
(2006)Methylmercury (MeHg) and total Hg (THg) concentrations in soil profiles were monitored in the Thur River basin (Alsace, France), where a chlor-alkali plant has been located in the city of Vieux-Thann since the 1930s. Three ...
-
(2006)A comprehensive set of high-precision Fe isotope data for the principle meteorite types and silicate reservoirs of the Earth is used to investigate iron isotope fractionation at inter- and intra-planetary scales. 14 chondrite ...
