Abstract. Ocean alkalinity enhancement (OAE) is an emerging strategy that aims to mitigate climate change by increasing the of seawater. This approach involves ocean enhance its capacity absorb and store carbon dioxide (CO2) from atmosphere. chapter presents overview technical aspects associated with full range OAE methods being pursued discusses implications for undertaking research on these approaches. Various have been developed implement OAE, including direct injection alkaline liquid...
Warm and humid climatic conditions in tropical regions can optimise the efficiency of enhanced rock weathering (ERW) as a carbon dioxide removal pathway. However, potential agronomic co-benefits (e.g., yield, nutrition, soil health) that might result from treating crops with silicate powder are less constrained, particularly context smallholder farming is ubiquitous throughout like Sub-Saharan Africa. In March 2024, Flux coordinated United Nations Convention to Combat Desertification (UNCCD)...

The South Atlantic Aptian "Pre-salt" shrubby carbonate Formations of Brazil and Angola are major interest for the oil industry due to their potential hydrocarbon accumulations. Although general sedimentology these deposits is widely recognised be within saline, alkaline lakes in rift volcanic settings, specific genesis morphologies remains unclear. This study reports first petrographically comparable carbonates amongst other microfacies from an Anthropocene limestone formed under...
Highly alkaline (pH 9–12) waters can arise from a range of globally significant and environmentally impactful industrial processes such as lime, steel cement production, alumina refining energy generation (e.g. combustion ashes). Such residue storage sites are often characterized by extreme geochemical conditions that be hazardous to aquatic life but quickly becoming critical focus for resource recovery carbon capture initiatives. The very high rates mineral precipitation at these give rise...
The main source rock (SR) of the Aquitaine Basin, most important oil province in France, corresponds to organic-rich marine limestones Upper Kimmeridgian age (Lons Formation Béarn area and Parnac Quercy area). In order better characterize their depositional environment, particular conditions accumulation preservation organic-matter, a sedimentological, micropaleontological geochemical study Crayssac section (Quercy) has been performed. Organic-rich sediments are argillaceous (65 99% CaCO 3 )...
Abstract This study aims to compare the fabrics of anthropogenic carbonates downstream lime and steel disposal sites with models carbonate precipitation from natural systems elucidate potential drivers, mechanisms, morphological similarities, predictability in 3D facies distributions depositional these systems. For this purpose, a combination sedimentological, mineralogical geochemical approaches is conducted including analysis microfacies (petrographic microscope electron microscopy), X‐ray...
Ocean Alkalinity Enhancement (OAE) emerges as a promising strategy capable of sequestering several gigatons CO2 annually from the atmosphere and store it in ocean for extended periods (>1000 years). To achieve this objective, artificial alkalinity is introduced into surface through alkaline solutions or spontaneous dissolution solids. When contemplating solids OAE, primary challenge lies generating substantial quantities fine grained (90m2/g). However, efficiency both hydrated carbonates...
Removing large volumes of CO2 from the atmosphere, as well rapid and deep emission reductions, may be required to meet goals Paris Agreement. This has catalyzed recent attention on carbon dioxide removal (CDR) approaches that can remove more atmosphere than they emit. The oceans absorb approximately 25% is emitted which causes acidification adds stress experienced by some shell-forming organisms. A relatively inexpensive process for creating a hydrated calcium carbonate, ikaite, could used...
<p>Over the last decennia, alkaline leachates from weathering of legacy steel slag disposal sites have affected surrounding soils and drainage streams. The hyperalkaline hypersaline conditions around these are comparable to extreme paleo environments such as lakes in rift volcanic settings. Investigating carbonate deposits forming man-made systems provides a unique opportunity link ongoing physical microbial processes their resultant...
