(2006)In order to examine whether the anelastic strain recovery (ASR) method can be applied for determining the in situ stress in hard rocks at great depths, the anelastic strain recovery of oriented cores was measured in six ...
-
(2006)Irreversible thermodynamic theories with internal state variables can be used to derive a general constitutive law for both transient and steady-state behaviours of rocks. This constitutive law can represent the concepts ...
-
(2006)The presence of three families of hopanoic acids, 17,21-secohopanoic acids, 25-norhopanoic acids, and 28-norhopanoic acids, is discussed. Oils from West Siberia and tar balls from the Seychelles Islands were found to contain ...
-
(2006)Illite is a dioctahedral K-deficient mica with an interlayer cation content of 0.6-0.85 atoms per formula unit. 1M and 2M1 are the illite polytypes more abundant in nature. Because illite is one of the major component of ...
-
(2006)In the uppermost Hauterivian sediments of the western Tethys, a short-lived anoxic event (Faraoni event) is documented both in the form of an interval enriched in organic matter (pelagic realm) and in a condensed interval ...
-
A 164 KA RECORD OF ENVIRONMENTAL CHANGE IN THE AMERICAN SOUTHWEST FROM A CARLSBAD CAVERN SPELEOTHEM (2006)A horizontal core 2.8 m in length drilled from the Georgia Giant column in Carlsbad Cavern provides climate information for the last 164 ka. Forty-six alpha spectrometric U-series ages determined at intervals of ~ 7.6 cm ...
-
(2006)The Euro-Mediterranean Seismological Center (EMSC) is in charge of collecting parametric data to operate a real-time information and alert system for potentially damaging earthquakes and to publish a comprehensive seismological ...
-
(2006)The Onsen site is an active submarine hydrothermal system hosted by the Desmos caldera in the Eastern Manus Basin, Papua New Guinea. The hydrothermal fluid is very acidic (pH=1.5) and abundant native sulfur is deposited ...
-
(2006)Detrital clay mineralogy is controlled by weathered source rock, climate, transport and deposition that in turn influence the spectral gamma-ray (SGR) response of resultant sediments. Whilst a palaeoclimate signal in clay ...
-
(2006)Lipids extracted from sediments in a saline seep in the Salt Basin of Lancaster County, Nebraska included alkanes, alkenes, alkanols, phytol, C27-30 sterols, C30-32 hopanoids, tetrahymanol, glycolipid and phospholipid fatty ...
-
(2006)By a pin-on-disk frictional experiment simulating the motion of an asperity on a fault plane, we observed photon emissions from the gap between the quartz disk and pins made of natural semiconductor or insulator minerals ...
-
(2006)Data from the temporary TRANSALP seismic network were analysed to investigate the seismic anisotropy in the upper mantle beneath the Eastern Alps. We operated mostly short period and some broadband stations in a dense ...
-
(2006)Employing USGS earthquake data for Indian region and very low frequency (VLF, 3 kHz) subsurface electric field data obtained by using a borehole antenna at Agra in India, statistical analysis has been carried out to identify ...
-
(2006)Magmatic and metamorphic zircons have been dated from ductilely deformed gabbroic dykes defining a dyke swarm and signifying crustal extension in the northern part of the Hengshan Complex of the North China Craton. These ...
-
(2006)A high-resolution pollen record, c. 50 yr/sample, from terminal lake sediments in the Shiyang River drainage basin on the present margin of the summer monsoon was used to reconstruct vegetation and climate history during ...
-
(2006)Decades of work have shown that trace- to minor-amounts of hydrous components commonly occur in minerals whose chemical formula would be normally written without any hydrogen, namely, the nominally anhydrous minerals (NAMs). ...
-
(2006)The gravity anomaly field of the Tyrrhenian basin and surrounding regions reflects the complex series of geodynamic events active in this area since the Oligocene-Miocene. They can resume in lithospheric thinning and ...
-
(2006)This paper investigates whether it is possible to find a solar signature in the current Earth's climatic warming. The attempt seems audacious as, on one hand, solar output variability on the atmosphere is far to be understood, ...
-
(2006)A 40 m long sediment core covering the 1000-9600 years BP period was retrieved from the Dumont d'Urville Trough off Adelie Land, East Antarctica, during the MD 130-Images X-CADO cruise. This sedimentary sequence allows the ...
