Exposed and un-remediated metal(loid)-bearing mine tailings are susceptible to wind and water erosion that disperses toxic elements into the surrounding environment. Compost-assisted phytostabilization has been successfully applied to legac...
Influence of clay mineral weathering on green rust formation at iron-reducing conditions [0.03%]

Green rusts (GR) are important drivers for trace metal and nutrient cycling in suboxic environments. We investigated whether green rusts would incorporate aluminum (Al) or other elements from naturally-formed clay minerals containing easily...

Geochemical transformations beneath man-made ponds: Implications for arsenic mobilization in South Asian aquifers [0.03%]
人工池塘下方的地球化学转化：对南亚含水层砷动员的影响

The role of man-made ponds on arsenic mobilization was examined in Bangladesh. Here, we describe a field experiment that shows how recharge from a newly constructed pond creates a reactive front that moves downward into the underlying aquif...

Nitrogen, the most dominant constituent of Earth's atmosphere, is critical for the habitability and existence of life on our planet. However, its distribution between Earth's major reservoirs, which must be largely influenced by the accreti...

The chemical and isotopic signatures of moderately volatile elements are useful for understanding processes of volatile depletion in planetary formation and differentiation. However, the fractionation factors between gas and melt phases dur...
Potassium distribution and isotope composition in the lithospheric mantle in relation to global Earth's reservoirs [0.03%]
地幔岩石圈钾的分配和同位素组成与全球地球储库的关系研究

Recent analytical advances have provided means to measure potassium (K) isotopes in various terrestrial materials, but little is known about K distribution and stable isotope composition in the lithospheric mantle because of: (a) common low...
New constraints from 26Al-26Mg chronology of anorthite bearing chondrules in unequilibrated ordinary chondrites [0.03%]
来源于未平衡普通球粒陨石中含长石球粒的26Al-26Mg同位素体系年龄约束的新限制

Guillaume Siron et al.
26Al-26Mg ages were determined for 14 anorthite-bearing chondrules from five different unequilibrated ordinary chondrites (UOCs) with low petrologic subtypes (3.00-3.05). In addition, oxygen three isotopes of these chondrules were also meas...
Timing of Martian Core Formation from Models of Hf-W Evolution Coupled with N-body Simulations [0.03%]

Determining how and when Mars formed has been a long-standing challenge for planetary scientists. The size and orbit of Mars are difficult to reproduce in classical simulations of planetary accretion, and this has inspired models of inner s...
