近日,矿床学领域权威期刊《Economic Geology》刊发我校资源学院和GPMR国家重点实验室李建威教授团队和昆士兰大学放射性同位素实验室合作的研究成果——首次利用LA-(MC)-ICPMS方解石U-Pb测年法精确确定了卡林型金矿床的形成时代。这是该团队继卡林型金矿成矿流体来源与演化示踪研究“Noble gases fingerprint the source and evolution o...
The rare earth element (REE) partition coefficients between calcite and aqueous solution were obtained experimentally under the conditions of pH, ionic strength and REE concentration level in the par...
Aragonite and calcite often coexist; as such, separating these very similar minerals is an important step in undertaking research on these two phases individually. One approach to discriminating betw...

Evidence of increasing concentrations of dissolved carbon dioxide, especially in the surface ocean and its associated impacts on calcifying organisms, is accumulating. Among these organisms, benthic a...
Freshwater Pliocene sand and clays found near Lipovljani in western Slavonia, Croatia, contain gastropods preserved by diagenetic mineral incrustations of alternating calcite and siderite. The geochem...
Identification of calcite and aragonite is very important for studying different fossil or recent biomineralized skeletons. Problem occurs when scanning electron microscopy is used for studying calcit...
The dissolution of settling calcite at the Hawaii Ocean Time-Series Sta. ALOHA in the North Pacific is examined using a calculation of the calcite saturation state based on 5 yr of alkalinity measure...
This paper examines the potential for calcium carbonate to reduce phosphate pollution in freshwaters by co-precipitation, a process known as a "self cleansing mechanism". Calcium carbonate saturation ...
Fluids within fault zones can change the physical and chemical properties of fault materials and have a substantial influence on faulting. Therefore it is important to understand the nature and timing...
Homogeneous partition coefficients (D) for Ra and Ba in calcite were determined from coprecipitation experiments using the Continuous Addition Method (CAM). The D-values derived for Ra and Ba are: DR...
BIOSOPE cruise covered an oceanographic transect through the centre of the South Pacific Gyre (SPG) from the Marquesas archipelago to the Peru-Chile upwelling (PCU). Water samples from 6 depths in the...
Production, oxygen uptake, and sinking velocity of copepod fecal pelletsegested byTemora longicorniswere measured using a nanoflagellate (Rhodomonassp.), a diatom (Thalassiosira weissflogii), or a coc...
The Baltic and Black Seas are both brackish, that is to say both have salinities intermediate between freshwater and seawater. The coccolithophore Emiliania huxleyi is abundant in one, the Black Sea, ...
A partition coefficient for copper (DCu) in foraminiferal calcite has been determined by culturing individuals of two benthic species under controlled laboratory conditions. The partition coefficient ...
