Comparative Geochemical Analysis of Ordovician and Mississippian Cherts in Relation to the Northern Arkansas and the Tri-State Mississippi Valley-type Ore Districts
… indicate that the Mississippi Valley-type (MVT) ores were produced from a mixing and cooling of these sedimentary basinal brines by meteoric or connate waters. Reduction of sulfate to sulfide is one of the possible mechanisms by which MVT ore precipitation may be recognized. Organics …

Prediction of Mississippi-Valley type ore fluid metal concentrations from solid solution metal concentrations in ore-stage minerals
Mississippi-Valley-type (MVT) deposits have some of the greatest enrichments of Pb, Zn, Ba, and F in the Earth's crust. Fundamental to understanding how these elements were transported and precipitated to form MVT deposits is knowledge of their concentrations in the ore fluids. Recent research …

The effects of structured variation in nectar standing crop on currency choice and optimal foraging by bumble bees
… from expectations of the Marginal Value Theorem (MVT). Bees apparently assess inflorescence quality on a per-patch basis, changing their exploitation behavior in response to poor or rewarding inflorescences as expected from a speed-accuracy trade-off, rather than maximizing their overall average …

Depression of pyrite in polymetallic sulfide flotation using chitosan-grafted-polyacrylamide polymers
… complex sulfide ore of Mississippi Valley Type (MVT) showed that Chi-g-PAM outperformed other pyrite’s depressants at producing less pyrite-diluted concentrates. Statistical optimization of the flotation process of MVT ore in relation to the structural characteristics of Chi-g-PAM (i.e., degree …

Re-evaluation of Kombat-style mineralisation and implications for exploration in the Otavi mountainland, Namibia
… ore at the Kombat Mine can be classified as an MVT-type deposit, whereas, the Fe-Mn ore can be classified as a stratiform-syn-sedimentary deposit. The formation of the MVT-type deposit is associated with a hydrothermal fluid system with a mean temperature of 183°C and mean salinity of 12.85 NaCl …

Source Constraints of Ore Metals in Mississippi Valley-type Deposits in Central and Eastern Tennessee using Pb Isotopes
<p>The Mississippi Valley-Type (MVT) Central and East Tennessee (TN) Districts contain economically significant lead-zinc deposits that occur in the Early Ordovician carbonates of the Knox Group. Although both districts share similar host rock, have similar temperatures of formation, and typically …

Paleomagnetic and mineral magnetic studies of zinc-lead ore deposits in the Metaline (Washington state, USA) and Midlands (Ireland) ore fields
… (Ireland) ore fields exhibit features of both MVT and SEDER deposits, and therefore, play an important role in the debate over genetic models for MVT - SEDER deposits, including the structural controls on ore mineralization, syngenetic versus epigenetic models, and the origin and migration …
