Basalt weathering laws and the impact of basalt weathering on …
Dec 30, 2003 · This study examined the chemical composition of river waters in basaltic environments to characterise the chemical weathering of basalts and quantify the atmospheric CO 2 consumption rates associated with basalt weathering.
Temperature dependence of basalt weathering - ScienceDirect
Jun 1, 2016 · Relative to their coverage of land area, weathering of basalt contributes a disproportionate share of the silicate-derived alkalinity flux delivered to the oceans, so climate sensitivity of CO 2 consumption during basalt weathering can be globally important even if basalts account for a modest fraction of the terrestrial surface.
The geochemical evolution of basalt Enhanced Rock Weathering …
Apr 1, 2024 · Abstract. Substantial quantities of fine-grained basaltic dust have fallen on South Iceland soils over at least the past 3300 years, making this region an ideal natural analogue to define the long-term consequences of current Enhanced Rock Weathering efforts.
Enhanced Rock Weathering - MIT Climate Portal
Nov 9, 2023 · Enhanced rock weathering is a strategy to help address climate change by taking carbon out of the air and storing it in rocks. It is one of several “carbon removal” techniques that target carbon dioxide (CO 2), the most important climate-warming greenhouse gas humans have been adding to the atmosphere.
Removal of atmospheric CO2 by rock weathering holds promise …
Jul 8, 2020 · Beerling et al. 1 demonstrate that enhanced rock weathering, achieved by adding crushed basalt or other silicate material to soil, is an effective strategy for removing carbon dioxide from the...
Potential for large-scale CO2 removal via enhanced rock weathering …
Jul 8, 2020 · Basalt, an abundant fast-weathering rock with the required mineral chemistry, could be ideal for implementing land-based ERW because of its potential co-benefits for crop production 18 and soil...
Potential CO2 removal from enhanced weathering by ecosystem …
Jul 26, 2021 · Achieving sufficiently high net CO2 removal will require upscaling of basalt mining, deploying systems in remote areas with a low carbon footprint and using energy from low-carbon sources.
Basalt weathering laws and the impact of basalt weathering on …
Dec 1, 2003 · Basaltic river waters are characterised by relatively high Na-normalized molar ratios (Ca/Na: 0.2–3.9; HCO3/Na: 1–10; Mg/Na: 0.15–6) in comparison with those usually observed for river draining...
Weathering of Basalt: Changes in Rock Chemistry and Mineralogy
Jan 1, 1987 · The weathering of eastern Australian basalts, sampled from the rounded, hard, core-stone to the rind of softer weathered material, has been examined by bulk chemical analyses, thin section pe-...
Frontiers | Enhanced Weathering Using Basalt Rock Powder: …
May 16, 2022 · This technique aims to accelerate natural weathering, a process that has been responsible for stabilizing climate over geological timescales, which naturally captures 1.1 Gt of CO 2 per year (or ca. 3% of current global CO 2 -emissions; Strefler …
