Variations in minor and trace metals in sphalerite from mississippi valley-type deposits of the Ozark region; genetic implications

Trace and minor elements in sphalerite: A LA-ICPMS study

“…Trace element data for sphalerite and other sulfides have also been used to identify zonation within an orefield or province (e.g., Monteiro et al, 2006). For some provinces, e.g., Zn-Pb deposits in the Eastern Alps, large volumes of trace element data exist for sphalerite (Viets et al, 1992;Schroll, 1996Schroll, , 1997Kuhlemann et al, 2001).…”

Chemical characteristics of lead-zinc ores from North Vietnam, with a special attention to the In contents

“…et al (2009) Kohno et al, 2008). MVT deposits were named after lead-zinc ore deposits in the central part of Mississippi Valley, U. S. A., for those having the following characteristics (Ishihara, 1985): MVT ores usually have very low contents of Fe (300~ 20,000 ppm) but high contents of Cd (3,000 ~15,000 ppm) in the sphalerite (Viets et al, 1992), or Cd 390 ~50,000 ppm with a mean of 4,850 ppm in the bulk ore samples (Schwartz, 2000). High In-sphalerite and pyrrhotite cannot be concentrated in MVT ores, because these minerals occur in a high-temperature environment of hydrothermal system (Ohta, 1995).…”

Trace element contents in galena and sphalerite from ore deposits of the Alcudia Valley mineral field (Eastern Sierra Morena, Spain)

“…In this regard, Hall and Heyl (1968) and Viets et al (1992) reported differences in trace element contents in Pb-Zn ores from different mining districts, but all the deposits studied belong to a single model, the Mississippi Valley type. Hall and Heyl (1968) also found poorly-defined zonation, particularly in Ag and Sb, with regard to the supposed mineralizing focus (feeders) in the Illinois-Kentucky district.…”

“…Hall and Heyl (1968) also found poorly-defined zonation, particularly in Ag and Sb, with regard to the supposed mineralizing focus (feeders) in the Illinois-Kentucky district. Viets et al (1992) demonstrated a clear influence of the host rocks in the mineralizing processes, with some trace elements (Cu, Ga and Ge in sphalerite) characteristic of that phenomenon.…”

“…Published papers on the behaviour of trace elements in ores are scarce and only focused on Mississippi Valley deposits (MVT) in the USA (Hall and Heyl, 1968;Viets et al, 1992). There have also been some classification attempts based on the silver content in the ore, such as the works by Bauchau (1971) and Beaudoin and Sangster (1992), but the content of these papers is far from the topic of the present work.…”
