Blasting operations in open-cast mines are crucial for mineral extraction but also come with significant environmental and structural risks. The peak particle velocity (PPV) generated during blasting is a key metric for assessing the impact of blasting vibrations on surrounding structures and the environment. Accurate PPV prediction is essential fo...

Mantle Oxidation by Sulfur Drives the Formation of Giant Gold Deposits in Subduction Zones Academic Background Most of Earth’s metal resources are concentrated in magmatic arc environments, and subduction zones are the primary regions for mass exchange between the mantle and crust. Fluids released from subducting slabs are believed to oxidize the o...
