Common Minerals Found in MVT Deposits: Galena (Lead Sulfide – PbS): Galena is a primary ore mineral for lead and is commonly found in MVT deposits. It forms cubic or octahedral crystals and has a metallic luster. Sphalerite (Zinc Sulfide – ZnS): Sphalerite is the primary ore mineral for zinc in MVT deposits. It often occurs alongside galena and can exhibit a …

tectonic conditions that predict the largest clastic-dominated lead-zinc deposits. We show that the largest potential for metal endowment is expected in narrow asymmetric rifts at a distance of several tens of kilometres to the shore (Glerum et al., 2023). Characterized by rift migration, these rifts generate a wide and a narrow conjugate margin.
