近日,中国地质大学资源学院和地质过程与矿产资源国家重点实验室李建威团队有关青藏高原东缘玉龙超大型斑岩铜矿床风化壳(U-Th)/He年代学的研究成果发表在地学领域重要综合期刊《Earth and Planetary Science Letters》上。该文第一作者为地质过程与矿产资源国家重点实验室邓晓东研究员,通讯作者为资源学院李建威教授。
Chemical weathering can control how susceptible bedrock in river beds is to erosion, according to new research In addition to explaining how climate can influence landscape erosion rates, the r...
This study examines the distribution of rare earth elements (REEs) in an 18–4.5 ka stalagmite in southwestern Japan, with the aim of assessing the utility of such data in paleoenvironmental reconstru...
Dissolved ion analyses of stream water were conducted monthly in three catchments of varying bamboo coverage of similar geological setting for one year. We found that the concentration of dissolved S...
The strontium isotope composition of seawater has varied over geological time in response to changes in the rates of continental weathering relative to ocean crust alteration. However, the potential o...
The chemical weathering of rock proceeds by water-rock interaction. During weathering geochemically mobile elements, alkali and alkali-earth elements are easily leached from rocks, leaving the residua...
Abstract: The upper 15–20 m of a 200 m thick lateritic weathering profile on Precambrian itabirites of Capanema, Brazil, reveals a genetic pathway for the formation of hematitic and goethitic nodules ...
Atmospheric acidic deposition introduces hydrogen ions to terrestrial and aquatic ecosystems, which become partially neutralized by chemical weathering. In the southern Alps of Switzerland, small catc...
If a series of rock samples with granitic composition in various stages of chemical weathering is ground in a mortar with distilled water and the pH of the slurry produced is determined, it will be ev...
