Textural identification of basaltic rock mass using image processing …
A new approach to identify the texture based on image processing of thin sections of different basalt rock samples is proposed here. This methodology uses RGB or grayscale image of thin section of rock sample as an input and extracts 27 numerical parameters. A multilayer perceptron neural network takes as input these parameters and …

Soil carbon turnover and balance in the priming effects of basalt
Purpose. Basalt weathering has the potential to absorb and sequester CO 2 as inorganic carbon, while its weathering byproducts, montmorillonite and kaolinite, have the capacity to stabilize organic carbon. Nonetheless, the practical viability of basalt weathering in achieving the stabilization of inorganic carbon and its impact on organic …

Costs for distributing basalt on a sufficiently large scale would include mining and crushing the rock, transport and distribution. Goll says that a cost of roughly $150 per tonne of removed carbon dioxide is realistic, assuming that basalt is applied to land reasonably close to human infrastructures using aircraft.
