On Antigua, the south of the island is mainly calc-alkaline volcanic rock such as dacite and quartz basalt or andesite, along with limestone lenses, agglomerate and tuff formed Basalt is an aphanitic (fine-grained) extrusive igneous rock formed from the rapid cooling of low-viscosity lava rich in magnesium and iron (mafic lava) exposed at or very near the surface of a rocky planet or moon. More than 90% of all volcanic rock on Earth is basalt. Rapid-cooling, fine-grained basalt is chemically equivalent to slow-cooling, coarse-grained gabbro. The eruption of basalt lava is observed bBasalt

Can ‘enhanced rock weathering’ help combat climate change?

As a cliff, or piled up in the quarry, the basalt weathers very slowly. To maximise the carbon removal it needs to be spread across a greater area. And that's where local farmers come in,Elevation of the basalt quarry is 54 m, and its distance to planned shore structures varies between 3–10 km. Limestone quarry is located between 20–30 km to the East of the region.General view of (a) basalt quarry, (b) typical log of basalts in

Senegal quarry takes a bespoke approach to weighing

Vicat Group has deployed a bespoke weighing solution from US tech company Topcon for use in its Gécamines Quarries site in Senegal. By Liam McLoughlin. The Gécamines Quarries site produces three million tonnes of basalt rock and 500,000 tonnes of limestone a year. Every year, three million tonnes of basalt rock, from gravel to Evaluation of blast efficiency in quarrying of aggregate stones is one of the most important decisions that should be made by quarry operators for productivity assessment. The regulatory authorities also evaluate blast efficiency for environmental safety compliance. In carrying out this task, there is usually a conflict of interests Evaluation of blast efficiency in aggregate quarries: facts and
