Reactivity of laser-cleaned stones to a SO2 ageing test
Materiales de Construccion, 2004 In order to study the reaction or susceptibility of Nd:YAG laser cleaned stones to polluted atmospheres, several types of stone, both cemented (limestone) and crystalline (marble, granite), were exposed to an atmosphere having simulated SO2 pollution ...

How the Sima de los Huesos was won
The Anatomical Record, Volume 307, Issue 7, Page 2225-2245, July 2024.Abstract Although the first discovery of a human fossil in the Sima de los Huesos took place in 1976, systematic excavations did not begin there until 1984. Since then, this site has been continuously excavated in month‐long camps. The site is dated by different radiometric techniques to between 430,000 and 300,000 years ago.

Volcanic Unrest After the 2021 Eruption of La Palma
Geophysical Research Letters, Volume 51, Issue 11, 16 June 2024.Abstract La Palma, Canary Islands, had its largest historical eruption in 2021. From January 2022 to May 2023 there were >2,100 seismic events, primarily at depths ≤20 km, prompting us to update the deformation and modeling study, using interferometric synthetic aperture radar observations and a last generation interpretation tool.

Ornamental granite durability: evaluation of damage caused by salt crystallization
Materiales de Construccion, 2008 The salt crystallization test is used to evaluate damage caused by soluble salts that penetrate stone and subsequently crystallize in its voids (pores or cracks). The present article discusses the findings for four ornamental granites (gris alba, grissal,

Magmatic Storage and Volatile Fluxes of the 2021 La Palma Eruption
Geochemistry, Geophysics, Geosystems, Volume 25, Issue 6, June 2024.Abstract The 2021 La Palma eruption (Tajogaite) was unprecedented in magnitude, duration, and degree of monitoring compared to historical volcanism on La Palma. Here, we provide data on melt inclusions in samples from the beginning and end of the eruption to compare the utility of both melt and fluid inclusions as recorders of magma storage.
