THE MAGMATIC EVOLUTION OF THE LAND'S END PLUTON, CORNWALL, AND ASSOCIATED PRE-ENRICHMENT OF METALS (2006)The peraluminous Land's End granite is one of the composite plutons forming the late-Variscan Cornubian batholith. The western part of the pluton hosts the Sn-Cu mineralisation of the St. Just mining district. The pluton ...
-
(2006)This paper reports a new 1° × 1° global thermal model for the continental lithosphere (TC1). Geotherms for continental terranes of different ages (> 3.6 Ga to present) constrained by reliable data on borehole heat flow ...
-
(2006)Solid solutions within the system Co-Fe-Ni-P were studied experimentally at 800 degrees C by means of the evacuated silica tube technique. Three broad sol id-solution series were detected in the system, tetragonal phi, ...
-
(2006)The Iti and Kallidromon ophiolites, in continental central Greece, consist mainly of an ophiolite melange overthrust by variably serpentinized ultramafic rocks. They include lherzolite and harzburgite; dunite pods occur ...
-
(2006)A 10 m sediment core from Academician Ridge in Lake Baikal was analyzed for its molecular composition using on-line TMAH (tetramethylammomium hydroxide) thermochemolysis. Major products are lignin phenols, n-C14 to C30 ...
-
(2006)As with modern organisms, the spatial and temporal distribution of fossil communities was controlled by both the physical setting in which the organisms lived and by the organisms' physiology and interactions. By studying ...
-
(2006)Seven peat and 40 dead wood remains (mountain birch) were sampled within and above the present treeline ecotone on two mountains (Rodjanoaivi, Koahppeloaivi/Staloskaidi) along the Tenojoki in northernmost Finnish Lapland. ...
-
(2006)Stable carbon and oxygen isotope analyses were conducted on pedogenic carbonates collected from a continuous, late Neogene terrestrial sequence located in Lantian, in the Chinese Loess Plateau. The sequence consists of 300 ...
-
(2006)A 12 m loess–paleosol section (La Angostura) from Tafi del Valle, Tucumán, Argentina was studied using rock magnetic measurements, geochemistry, Mössbauer effect, particle size and Nd isotopes in order to elucidate changes ...
-
(2006)A new paleomagnetic study has been carried out on Mesoproterozoic sediments in the Jixian area, North China. Detailed stepwise thermal demagnetization allows us to isolate three components from 141 oriented drill-core ...
-
(2006)The nature of the crust in the Laxmi Basin, western margin of India is an uncertain issue; more importantly this has implications on paleo-geographic reconstructions of the western Indian Ocean. We have analysed three ...
-
(2006)The dinoflagellate cyst, palynofacies and foraminiferal records from the Early Eocene Figols Group of the Spanish Pyrenees exhibit major changes associated with relative sea-level fluctuations and variations in efficiency ...
-
(2006)To understand the impacts of long-term climatic episodes and sea-level changes on mid-oceanic atoll sedimentation, the stratigraphic changes of litho- and bio-facies, and stratigraphic levels of freshwater diagenetic ...
-
(2006)The coordination chemistry of molybdenum was investigated in nine series of synthetic silicate glasses, including sodium disilicate (NS2), sodium trisilicate (NS3), albite (Ab), anorthite (An), Ab50An50, Ab30An70, diopside ...
-
(2006)This study examined the effect Of CO2 on NaCl solubility in hydrothermal fluid, with the synthetic fluid inclusion technique. Fluid inclusions of 30-40 wt% NaCl and 5 mol % CO2 were synthesized, and their halite dissolution ...
-
(2006)The Grove Mountains of East Antarctica are an inland continuation of the Pan-African Prydz Belt. The area is made up of high-grade metamorphic complex and numerous intrusive granitoid bodies including foliated charnockite, ...
-
(2006)We have characterized ferroaxinite (up to 95 mol.% of end-member composition) from a contaminated granitic pegmatite cutting the magnetite-rich portion of an Fe-skarn body near Malešov, Czech Republic, by means of ...
-
(2006)Syn- and post-orogenic Cu mineralization in the northern Xinjiang Paleozoic accretionary and collisional orogenic belt in northwestern China is of great economic interest. About 40 Cu-bearing deposits have been discovered ...
-
(2006)Determining the age of glacigenic sediments is difficult for many geochronological methods because of the lack of suitable materials for analysis. Luminescence dating can be applied to the mineral grains making up the ...
-
(2006)Carbon, oxygen and strontium isotope ratios were determined in the uppermost Neoproterozoic carbonate rocks at Pastores (SW Salamanca, Central Iberia). The low δ18O V-SMOW values (15-19‰) indicate an alteration of the whole ...
