Pegmatite lithium deposits formed within low-temperature country rocks [PDF]

open access: yesNature Communications
The global climate crisis is likely to lead to a potential supply risk of lithium (Li) over the coming decades. More than half of the world’s production of Li is derived from Li-bearing pegmatites.

Source Region Geochemistry From Unmixing Downstream Sedimentary Elemental Compositions

open access: yesGeochemistry, Geophysics, Geosystems, 2021
The geochemistry of river sediments is routinely used to obtain information about geologic and environmental processes occurring upstream. For example, downstream samples are used to constrain chemical weathering and physical erosion rates upstream, as ...

Characterization of chemical and carbon isotopic compositions of gases during thermochemical sulfate reduction and implications for gas origin and content

open access: yesScientific Reports, 2022
For identifying the occurrence and extent of thermochemical sulfate reduction (TSR) reaction of natural gas and better understanding the chemical and carbon isotopic variations in natural gas reservoirs, high-pressure hydro-pyrolysis with a special ...

Light Mo Isotopes of Post‐Collisional Ultrapotassic Rocks in Southern Tibet Derived From Subducted Indian Continental Crust

open access: yesGeochemistry, Geophysics, Geosystems, 2023
Recycling of molybdenum isotopes in continental subduction zones remains debated. In this contribution, we re‐visit the Mo isotope compositions of the Sailipu post‐collisional ultrapotassic rocks in the Himalaya‐southern Tibet orogen. These ultrapotassic

Underrated primary biogenic origin and lifetime of atmospheric formic and acetic acid

open access: yesScientific Reports, 2021
Formic and acetic acids are ubiquitous in the troposphere, playing an important role in the atmospheric chemistry. Recent model studies ended up with substantial low bias on their tropospheric budgets presumably due to a large missing biogenic source ...
