The surface geochemistry techniques widely employed during the 1960’s to 1980’s are effective at discovering near-surface deposits, but are largely ineffective for exploring under deep cover or for deep extensions of known mineralisation in a near-mine environment. Instead, mineral explorers must focus their attention on rapidly aggregating and synthesising disparate data to build into holistic...
The Kuh-Sorbi barite-Pb ± Cu deposit, which is located southeast of Mashhad in Khorasan Razavi Province of Iran, occurs as vein, open space filling, host rock replacement, and cement within the fault breccia in the Upper Triassic Nayband Formation metamorphosed carbonate rock unit. This deposit contains of barite (80–85%) and galena (10–15%), with small amounts of chalcopyrite and quartz. Barit...
