Salt Weathering and Inselbergs

“Salt Weathering” Distress on Concrete by Sulfates?

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...

The effect of cyclic salt weathering test on deterioration potential of granitoid rocks

In this study, the salt weathering effects on engineering properties and weight loss potential of three types of granitoid rocks were investigated. Sodium and magnesium sulfates tests were performed on core and aggregate samples. The cyclic salt weathering tests on core samples were done up to 90 cycles, while these tests on aggregate samples were done up to 40 cycles. The results showed that d...

Tropical inselbergs: habitat types, adaptive strategies and diversity patterns

(Tropical inselbergs: habitat types, adaptive strategies and diversity patterns). Inselbergs are isolated rock outcrops that rise abruptly above the surrounding plains. Granitic and gneissic inselbergs are geologically and geomorphologically old and occur throughout a broad spectrum of climatic zones. They form microclimatically and edaphically dry growth sites that support a highly specialized...

Perchlorate Salt Effects on Rock Weathering on Mars at the Phoenix Landing Site

Statement of the problem: The Phoenix Mission was the first to land in the polar regions on Mars. The mission revealed three surprising results: (1) The surface at the landing site had a very low concentration of large size rocks, (2) The unexpectedly sticky nature of the soil prevented it initially from falling through one of the instrument’s screens as planned, (3) Perchlorate salt was found ...
