How Copper, Nickel, and Arsenic Co-occur with Zinc-Lead Ores in the Lisheen Deposit, Ireland: Breakthroughs in Isotope Tracing and Deep Exploration

Abstract The Irish mineral field contains both zinc-lead deposits and copper-nickel-arsenic deposits, but the relationship between their formation is controversial. This study focuses on the copper-nickel-arsenic ores of the Lisheen deposit, analyzing their mineral characteristics, formation sequence, and chemical composition. The research found that these copper-nickel-arsenic ores and zinc-lead ores were formed from the same … Read more
