DOI: 10.1016/j.chemgeo.2018.05.021
Abstract: Abstract Chemical weathering of bedrock plays an essential role in the formation and evolution of Earth's critical zone. Over geologic time, the negative feedback between temperature and chemical weathering rates contributes to the regulation of… read more here.

DOI: 10.1038/s41467-017-01227-7
Abstract: Large Hesperian-aged (~3.7 Ga) layered deposits of sulfate-rich sediments in the equatorial regions of Mars have been suggested to be evidence for ephemeral playa environments. But early Mars may not have been warm enough to support… read more here.

DOI: 10.1038/s41598-019-53205-2
Abstract: Although bedrock weathering strongly influences water quality and global carbon and nitrogen budgets, the weathering depths and rates within subsurface are not well understood nor predictable. Determination of both porewater chemistry and subsurface water flow… read more here.

DOI: 10.2138/gselements.15.4.259
Abstract: A feedback between Earth surface weathering and climate is thought to be fundamental in maintaining Earth's habitability over long times-cales, but investigating this control in the modern world is difficult. The geologic record of cycles… read more here.

DOI: 10.5194/bg-20-1879-2023
Abstract: Abstract. In a future warmer climate, extremely dry, warm summers might become more common. Soil weathering is affected by temperature and precipitation, and climate change and droughts can therefore affect soil chemistry and plant nutrition.… read more here.
