Sediments deposited on the bottom of Lake Baikal have contributed to the understanding of
a long-term environmental history of continents. Rare earth elements (REEs) along with …

We evaluated both the spatial distribution of gadolinium (Gd) and other rare earth elements
(REE) in surface waters collected in a transect of San Francisco Bay (SFB) and their …

In some geological environments, the tetrad effect can be observed as a split of rare earth
element (REE) patterns into four rounded segments. A new method is proposed to quantify …

Abundances of rare earth elements plus Y (REE) were determined for granitic rocks, Tertiary
sedimentary rocks, and related groundwater in the Tono area, central Japan. Tetrad effects …

Radiolarian chert deposited on a continental shelf occurs in the Middle Permian Gufeng
Formation on the northeastern Yangtze platform, China. The sedimentary environments of …

Résumé Total and dissolved rare earth element (REEs) and U concentrations were
determined for waters from Lake Paranoá (Brasilia, Brazil) sampled in the dry (November …

塔里木盆地顺托果勒低隆起北部中下奥陶统碳酸盐岩储层中发育多期方解石脉体,
对流体活动历史和油气成藏过程都具有重要指示作用. 本研究基于对方解石脉体薄片观察 …

Plots of chondrite-normalised rare earth element (REE) patterns often appear as smooth
curves. These curves can be decomposed into orthogonal polynomial functions (shape …

Five species of bivalves (Japanese littleneck, blue mussel, trough shell, Stimpson's quahog,
and Japanese dosinia) were collected from three different sites in Tokyo Bay and their shells …
