“…The ore-hosting breccias include discordant domes and columns that may be interconnected to concordant breccias. The breccia tops are vuggy and porous and contain mainly open-space filling mineralization while replacement mineralization is dominant near the base of the breccias (Rogers & Davis, 1977). The regional distribution of the Southeast Missouri orebodies closely follow the pinchouts of the Lamotte Sandstone (Kisvarsanyi, 1977).…”

“…Because most MVT deposits are mineralogically simple, mineralogic zonation has been described for only a few areas (Southeast Missouri, Pine Point, and Upper Mississippi Valley). Lead, zinc, iron, copper, nickel, and cobalt abundances are zoned in mineralogically complex deposits of the Southeast Missouri district (Grundmann, 1977;Rogers and Davis, 1977;Sweeney and others, 1977;Hagni, 1983;Mavrogenes and others, 1992). In the Upper Mississippi Valley district, a local zinc-copper belt is flanked by barite, whereas lead is widespread (Heyl and others, 1959).…”

This preliminary compilation of geoenvironmental models represents a monumental effort, completed within a very short time frame, by the authors of the individual models. All of the authors are to be commended for a job well done. I wish to express my thanks to Bill Miller and Ted Theodore who agreed to review the first version of the compilation. This was a huge job, completed with remarkable swiftness, for which I am very grateful. I would also like to thank

“…Consistent, well-developed metal or element zoning is not a typieal feature of MVT deposits. However, some large distriets such as Southeast Missouri, Upper Mississippi Valley, and Pine Point exhibit broad trends in metal ratios (Heyl et al 1959;Grundmann 1977;Rogers and Davis 1977;Kyle 1981). Table 4 summarizes elements that may be useful in geoehemieal exploration studies.…”

Sediment-hosted stratiform massive sulphide (Sedex) deposits and Mississippi Valley-type (MVT) deposits differ in morphology, but there is considerable overlap in their host rock lithology, regional setting, size, grade, metal ratios, age of host rocks, lead isotopes, sulphur isotopes, and genesis. Recent advances in the understanding of basin-derived formation fluids provide a framework for interpreting the lithogeochemical signatures of these deposits. The composition of the ore fluids for both types of deposits is controlled in part by fluid-rock reactions within sedimentary basins, but the nature of the sediments in the basins, the source of the fluids, the thermal gradient in the basin, the migratory history of the fluids, and the physical and chemical conditions in the deposition al environment cause variations in the lithogeochemical patterns present. Studies of modern sedimentary formation waters indicate that diagenetic fluid-rock reactions in basins can liberate and dissolve significant amounts of metals. The most metal-enriched formation waters are brines with more than 200000 ppm total dissolved solids. Some brines contain more than several hundred ppm combined Fe, Zn, Pb, and Ba, and minor amounts of Cu, Ag, Mn, Cd, As, Sb, Ni, Co, Mo, and Tl.Copper, Ag, As, Sb and Ba are reported in more than 60% of the Sedex deposits studied; Mn, Cd, Ni, Co, Au, Hg, Bi, B, Sn, Mo, F, Tl, Ge and Sr are reported in more than 20%; and V, Ga, In, Se, Cr and NH4 + are reported in more than 10% of the deposits. Geochemical variables which have received some exploration attention and which show promise as guides to Sedex deposits include: Tl, F, NH4 +, Hg, Pt, Pd, Zr, Cl-bearing minerals, rare earth elements, stable isotopes, and carbonaceous material.MVT districts were formed by ore-forming fluids which affected large volumes of the cmst. Widespread and isolated geochemical anomalies are, therefore, to be expected. Although there is a great diversity in deposit characteristics, it is possible to establish exploration criteria for additional deposits within a district or region. Geochemical analysis of insoluble residues has been used to define geochemical patterns that coincide with known ore trends and with ore-related geological features in the Southeast Missouri districts. Studies of rock alteration or identification of minerals precipitated from the brines can provide evidence of pathways used by the ore fluids. Hydrothermal dolomitization is the most important type of alteration; silicification is associated with ore in so me districts, and alteration of feldspars near ore has been identified in the Southeast Missouri lead district. Organic geochemistry and fluid inclusion studies are in progress and may yield practical exploration guides to MVT deposits.The presence of Cu, Mo, Pb, Zn, Ni, Co, Ag, Sb, As, Cd, and Ba in oil field brines/well scales, in MVT deposits, and in Sedex deposits lends credence to the use of these elements in lithogeochemical surveys. Many of the element associations described are bas...
