Converting industrial and agricultural waste streams into carbon-storing oxalate minerals Open
Carbon capture and storage has emerged as a crucial strategy for mitigating global warming. Ex situ mineralization, which converts CO₂ into stable carbonate minerals aboveground, promises to store carbon safely for geological timesca…

Carbon Storage in Coal Fly Ash by Reaction with Oxalic Acid Open
Coal combustion is one of the leading sources of CO2 emissions, and it is predicted to remain so for the foreseeable future. The environmental effects of coal burning can be partially offset by utilizing fly ash, which is a combustion bypr…

Impact of stylolite cementation on weathering rates of carbonate rocks Open
The weathering of carbonate rocks plays a significant role in the evolution of Earth’s surface. Such weathering is often accelerated by the presence of stylolites, which are rough, serated surfaces that form by dissolution under burial or …

Gypsum Precipitation under Saline Conditions: Thermodynamics, Kinetics, Morphology, and Size Distribution Open
Gypsum (CaSO4·2H2O) is the most common sulfate mineral on Earth and is also found on Mars. It is an evaporitic mineral that predominantly precipitates from brines. In addition to its precipitation in natural environments, gypsum also forms…

Impact of textural patterns on rock weathering rates and size distribution of weathered grains Open
Rock texture has a critical influence on the way rocks weather. The most important textural factors affecting weathering are grain size and the presence of cracks and stylolites. These discontinuities operate as planes of mechanical weakne…

Fracking Under the Microscope Open
During hydraulic fracturing large volumes of water are injected into subsurface shale formations.This injected fluid can interact with different phases present within the reservoir rock, potentially leading to mineral dissolution and the m…

Impact of grain size and rock composition on simulated rock weathering Open
Both chemical and mechanical processes act together to control the weathering rate of rocks. In rocks with micrometer size grains, enhanced dissolution at grain boundaries has been observed to cause the mechanical detachment of particles. …

Repulsion between calcite crystals and grain detachment during water–rock interaction Open
Weathering in carbonate rocks is often thought to be governed by chemical dissolution.However, recent studies have shown that mechanical detachment of tiny grains contributes significantly to the overall surface retreat.Whether this detach…

Weathering resistance of carbonate fault mirrors promotes rupture localization Open
Fractured rocks in fault zones regain their mechanical strength through a process called healing. A central pathway for healing involves the dissolution and reprecipitation of minerals in the fault zone which cements the fractured rocks du…
