(2006)Detailed records of spore-pollen assemblages, particulate organic matter (OM), dinoflagellate cysts and calcareous nannofossils provide new insights into the palaeoclimatic and palaeoceanographic conditions during formation ...
-
(2006)A 328 cm-long piston core (KODOS 02-01-02) collected from the northeast equatorial Pacific at 16°12′N, 125°59′W was investigated for eolian mass fluxes and grain sizes to test these proxies as a tool for the paleo-position ...
-
(2006)Changes in ice volume and resulting changes in sea level were determined for the late Oligocene (26-23 Ma, Astronomical Timescale, ATS) by applying δ18O-to-sea-level calibrations to deep-sea δ 18O records from ODP Sites ...
-
(2006)Hydroxyl (OH) content in diopside of one diamond-free ultrahigh-pressure (UHP) marble from the Kokchetav Massif, Kazakhstan, was estimated by a micro- Fourier transform infrared (FTIR) spectrometer. Two intrinsic diopside ...
-
(2006)The main objective of the present study was to clarify if the fernane derivatives 5-methyl-10(4-methylpentyl)-des-A-25-norferna-5,7,9-triene (MATH), 25-norferna-5,7,9-triene (MAPH), 24,25-dinorferna-1,3,5,7,9-pentaene (DAPH ...

TWINNING INDUCED BY THE RHOMBOHEDRAL TO ORTHORHOMBIC PHASE TRANSITION IN LANTHANUM GALLATE (LAGAO3) (2006)Phase-transformation-induced twins in pressureless-sintered lanthanum gallate (LaGaO3) ceramics have been analysed using the transmission electron icroscopy (TEM). Twins are induced by solid state phase transformation upon ...
-
(2006)Four structural-metamorphic zones separated by ductile shear zones comprise the Sulu high- to ultrahigh-pressure metamorphic terrane. From south to north, they are the southern high-pressure zone (0.2-0.4 GPa, 350-400 °C), ...
-
(2006)Gravity studies have delineated the largest ultramafic massif in New Zealand, embedded within a buried major SW Pacific crustal suture zone. This suture records terrane collision onto the Gondwana margin during the Mesozoic ...
-
(2006)Canister desorption of coal gas from freshly sampled coal is commonly used for exploratory assessment of the coalbed methane (CBM) potential of a basin or prospect, as well as for the sampling of gas for isotopic determination ...
-
(2006)The Yecheng profile, lying in the southwest Tarim Basin at the northern foot of the West Kunlun Mountains, comprises 4.5 km of conformable Miocene to Pliocene strata. The lower part of the section, the Wuqia Group, is ...
-
(2006)The Guadix topographic depression is a Neogene-Quaternary basin located in the central sector of the Betic Cordillera at the boundary between the South Iberian margin and the Alboran domain. This topographic depression is ...
-
(2006)Iskenderun Bay is a major shallow embayment in the eastern part of the Mediterranean Sea, where the African and Anatolian Plates converge. This tectonically active basin was investigated for oceanographic, sedimentological, ...
-
HIGH-PRESSURE BEHAVIOUR ALONG THE JADEITE NAALSI2O6-AEGIRINE NAFESI2O6 SOLID SOLUTION UP TO 10 GPA (2006)The volume variation as a function of pressure along the jadeite-aegirine solid solution was determined at room temperature up to pressures between 6.5 and 9.7 GPa by single-crystal X-ray diffraction. The unit-cell volumes ...

MANUEL ROCHA MEDAL RECIPIENT SHEAR STRENGTH OF ROCK JOINTS BASED ON QUANTIFIED SURFACE DESCRIPTION (2006)One of the primary objectives of this work is to improve the understanding of the frictional behaviour of rough rock joints under shear loads, and to relate its shear strength to the "shape" of the joint interface (roughness). ...
-
(2006)The Lodève basin, which contains an exceptional long and nearly uninterrupted profile of Early to Late Permian continental red beds, is well correlated to the other European Permocarboniferous basins. Together they cover ...
-
(2006)Calcretes are abundant in Late Quaternary channel and floodplain strata of the southern Ganga plains. In a key section at Kalpi, pedogenic carbonates (nodules, rhizoconcretions, and powdery carbonate) are present within ...
-
(2006)A well-constrained record of Miocene-Pliocene explosive volcanism is preserved within the broken foreland of Western Argentina along the Famatina Ranges. This paper focuses on the volcaniclastic record known as the Río ...
-
(2006)We use satellite imagery and field observations to investigate the distribution of active faults around Birjand in eastern Iran to determine how the transition between conjugate zones of faulting can be accommodated by ...
-
(2006)Neutron radiography and neutron tomography are techniques which are mature and readily accessible. They can be used to study the interior of large, complex objects with a resolution of ~100 μm, and observe non-periodic ...
-
(2006)The self-similarity of rocks on the macro-scale is well known—traditionally, the photographs of rock formations usually include a scale-defining object such as a coin, a hammer, a human silhouette, etc. We know now that ...
