Comparison between Salt crystallization weathering test and natural weathering in Mesozoic’s anisotropic rocks, a case study: Arakʾs Calcareous slates, Iran
Salt crystallization can severely damage anisotropic foliated rocks, therefore it is necessary to have an understanding of crystallization process. The present study was conducted to investigate the effect of salt crystallization on Arakʾs calcareous slates, as anisotropic rocks of Mesozoic. To compare salt crystallization weathering (EN 12370 norm was used up to 30 cycles) with natural weather...
متن کاملN2-fixing tropical legume evolution: a contributor to enhanced weathering through the Cenozoic?
Fossil and phylogenetic evidence indicates legume-rich modern tropical forests replaced Late Cretaceous palm-dominated tropical forests across four continents during the early Cenozoic (58-42 Ma). Tropical legume trees can transform ecosystems via their ability to fix dinitrogen (N2) and higher leaf N compared with non-legumes (35-65%), but it is unclear how their evolutionary rise contributed ...

متن کاملClimate change mitigation: potential benefits and pitfalls of enhanced rock weathering in tropical agriculture.
Restricting future global temperature increase to 2°C or less requires the adoption of negative emissions technologies for carbon capture and storage. We review the potential for deployment of enhanced weathering (EW), via the application of crushed reactive silicate rocks (such as basalt), on over 680 million hectares of tropical agricultural and tree plantations to offset fossil fuel CO2 emis...
متن کاملPost-Mining Landforms ― Engineering a Biological System
The construction of cover systems on decommissioned tailings storage facilities and waste rock dumps can represent one of the largest cost components of a mine closure project. There have been great advances in the understanding of the hydrology of cover systems in recent years, but some uncertainties in long-term performance remain. This paper describes some of the changes in engineering chara...
