-
(2006)This work is aimed to demonstrate the feasibility of a methodology for retrieving bio-geophysical variables whilst at the same time fully accounting for additional information on directional anisotropy. A model-based ...
-
(2003)Evidence is presented for retrograde reaction of silicate minerals with saline brine inside fluid inclusions during post-entrapment cooling. Ferropyrosmalite [(Fe,Mn)8Si6O15(OH,CI)10, where Fe>>Mn] has previously been ...
-
(2002)Many migmatites and granulites preserve evidence of a clockwise P-T evolution involving decompression (decrease in P) while close to the thermal peak. The extent of post-thermal peak reaction is influenced by several ...
-
(2001)The complexity of geophysical systems makes modelling them a formidable task, and in many cases research studies are still in the phenomenological stage. In earthquake physics, long timescales and the lack of any natural ...
-
(2002)We present a new global model for Recent plate velocities, REVEL, describing the relative velocities of 19 plates and continental blocks. The model is derived from publicly available space geodetic (primarily GPS) data for ...
-
(2004)In this work, the control exerted by the stress axes orientation on the evolution of seismic sequences developing in compressive and extensional regimes is analysed. According to the Anderson fault theory, the vertical ...

REVERSED CALCITE MORPHOLOGIES INDUCED BY MICROSCOPIC GROWTH KINETICS: INSIGHT INTO BIOMINERALIZATION (1999)This experimental investigation of calcite growth quantifies relationships between solution supersaturation and the rates of step advancement. Using in situ fluid cell atomic force microscopy (AFM), we show that the movement ...
-
(1998)The reaction of phlogopite plus quartz to enstatite, potassium feldspar, and aqueous fluid in the system KMASH-KCl was reversed at 2-12 kbar and 750-875 degrees C and at low H2O activities by reversal of the H2O content ...
-
(1987)The authors attempted to find a correlation between the distortion of partial hysteresis cycles and the strength of the thermomagnetization field. Studied was the effect of thermomagnetization on the way in which the ...
-
(2002)Available lithostratigraphic, tectonothermal, geochronological and paleomagnetic data from 2.1–1.8 Ga collisional orogens and related cratonic blocks around the world have established connections between South America and ...
-
(2006)There is a variety of methodologies used in the aquatic sciences and soil sciences for extracting different forms of Si from sediments and soils. However, a comparison of the published extraction techniques is lacking. ...
-
(1998)The known occurrences of oxalate minerals in deep diagenetic and hydrothermal environments are reviewed and new carbon isotope results are presented that cover, together with previously published data, 22 of 37 known ...
-
(1997)There are 96 approved PG (platinum group) - mineral species and more than 500 unidentified PG-phases on record. In addition, over 20 non-PG-minerals contain varying concentrations of one or more of the six platinum group ...
-
(2002)The availability of thousands of kilometers of deep seismic reflection profiles from the Paleozoic orogenic belts around the North Atlantic Ocean provides an unparalleled opportunity to synthesize the contrasts and ...
-
(1988)The major floristic and geochemical differences between bogs, fens, and swamps are summarized, and the most common peat types described. This is followed by a critical, historical review of the literature.The methods used ...
-
REVIEW OF THE OLDEST (4400-3600 MA) GEOLOGICAL AND MINERALOGICAL RECORD: GLIMPSES OF THE BEGINNING (2001)Known occurrences of rocks from the first billion years (>3550 Ma) form a minuscule ∼10,000 km2 of Earth's surface. The largest areas are in Greenland (Itsaq Gneiss Complex), Labrador and Western Australia, with smaller ...
-
(2003)By the beginning of the 21st century, 1227 species and subspecies of marine and brackish-water bivalves, assigned to 225 genera and subgenera of 54 families, were described from the Cenozoic of the Russian Far East by ...
-
(1988)This review focuses on those aspects of mesoscale models which require special techniques and parameterizations when modelling flow over complex terrain. The basic concepts and limitations of various approaches are discussed, ...
-
(1994)An overview is given of the atmospheric boundary layer (ABL) over both continental and ocean surfaces, mainly from observational and modelling perspectives. Much is known about ABL structure over homogeneous land surfaces, ...
