A study of nano-particle based silane consolidants for Globigerina limestone [PDF]
, 2013 This STEPS funded study focuses on the application of hybrid and nanoparticle loaded hybrid silane consolidants for the treatment of 'Franka' type Globigerina Limestone. Consolidants act by gluing the deteriorated stone material to the underlying healthy

The progress and prospects of potassium stable isotopes in hydrogeochemistry
Shuiwen dizhi gongcheng dizhi, 2023 Chemical weathering of silicate minerals is an important source for Ca, Mg, Na and K. However, in comparison with other major elements (e.g., Ca, Mg and Na) in waters, how K behaves during water-rock interaction remains poorly understood.

Strontium isotope compositions of river waters as records of lithology-dependent mass transfers : the Garonne river and its tributaries (SW France) [PDF]
, 2000 The relation of lithology in the drainage basin to the dissolved load of the Garonne river and its main tributaries, in southwestern France, was evaluated by determining 87Sr/86Sr ratios, and concentrations of major and trace elements during a 2-year ...

Silicate weathering in anoxic marine sediment as a requirement for authigenic carbonate burial
, 2020 We emphasize the importance of marine silicate weathering (MSiW) reactions in anoxic sediment as fundamental in generating alkalinity and cations needed for carbonate precipitation and preservation along continental margins.

Co-variation of silicate, carbonate and sulfide weathering drives CO2 release with erosion
Nature Geoscience, 2021 Global climate is thought to be modulated by the supply of minerals to Earth’s surface. Whereas silicate weathering removes carbon dioxide (CO2) from the atmosphere, weathering of accessory carbonate and sulfide minerals is a geologically relevant source

Lithologic Controls on Silicate Weathering Regimes of Temperate Planets [PDF]
The Planetary Science Journal, 2020 Weathering of silicate rocks at a planetary surface can draw down CO2 from the atmosphere for eventual burial and long-term storage in the planetary interior. This process is thought to provide essential negative feedback to the carbonate-silicate cycle (

Old carbon contributes to aquatic emissions of carbon dioxide in the Amazon [PDF]
, 2014 Knowing the rate at which carbon is cycled is crucial to understanding the dynamics of carbon transfer pathways. Recent technical developments now support measurement of the <sup>14</sup>C age of evaded CO<sub>2</sub> from fluvial

d13C tracing of dissolved inorganic carbon sources in Patagonian rivers (Argentina) [PDF]
, 2005 The main Patagonian rivers (Colorado, Negro, Chubut, Deseado, Coyle, Chico, Santa Cruz and Gallegos) were sampled between September 1995 and November 1998 to determine their chemical and isotopic compositions, the origins of the suspended and dissolved ...
