(PANGAEA, 2013-04-02)
-
(1993)Low paleolatitudes are very frequent in Eocene to Oligocene formations, particularly in the Tethyan mobile belt. These anomalies and their possible sources are discussed. They are neither due to unreliable results nor to ...
-
(2004)In recent years, it has become popular to attribute faunal change and mass extinction to impacts, volcanic eruptions, or climatic change. How well do these supposed causes compare to the excellent record of Cenozoic life, ...
-
(1997)The potential role of large earthquakes on the excitation of the Earth's free wobble has been the subject of various investigations. It is nowadays recognized that the coseismic moment released by large earthquakes is not ...

(1904)
-
(2005)Diel (24-h) changes in concentrations of rare earth elements (REE) were investigated in Fisher Creek, a mountain stream in Montana that receives acid mine drainage in its headwaters. Three simultaneous 24-h samplings were ...
-
(2001)A physiochemical model for the complex dielectric response of sedimentary rocks is used to invert broadband dielectric spectra for effective grain size distributions. The complex dielectric response of each grain within ...
-
(2000)The dielectric behavior of kaolinite, montmorillonite, allophane, and imogolite samples ad-justed to a water potential of 33 kPa was examined using a time-domain reflectometry method over a wide frequency range of 103-10 ...
-
(2004)DIFFaX simulations show that the 3R1 and 3R2 polytypes of hydrotalcites (HT) have distinctly different X-ray powder diffraction (XRPD) patterns. The HT samples obtained by coprecipitation as well as those subjected to a ...
-
(2005)Carbonate-intercalated layered double hydroxides of Co(II) and Ni(II) with Fe(III) and Al(III) were precipitated under different conditions (pH = 8-12; T= 25-80°C). All the samples are replete with stacking faults which ...
-
(2003)The quartz-water reaction SiO2 + 2H2O = H 4SiO40 is usually described by the following rate law: dm/dt = kd(S/M)(1 - m/meq , where m and meq are the real and equilibrium concentrations of silica in the solution, t is the ...
-
(2003)Elastic moduli are controlled mainly by the viscoelastic and microplastic behavior of rocks if stress and strain remain below the proportionality limit. Differences between measured static and dynamic elastic moduli are ...
-
(2001)By comparing the compositions of glacial and interglacial intervals of the Late Pliocene, Pleistocene, and Holocene from different parts of Lake Baikal, we demonstrate the use of the Baikal clay mineral associations as ...
-
(2003)Normal grain growth of calcite was investigated by combining grain size analysis of calcite across the contact aureole of the Adamello pluton, and grain growth modeling based on a thermal model of the surroundings of the ...
-
(2005)Fulvic acids from deep clay formations have been isolated by the International Humic Substances Society (IHSS) standard protocol and analyzed. Near edge X-ray absorption fine structure (NEXAFS) spectroscopy reveals, that ...
