You are welcome to contribute papers to Special Issue “Pyrite Varieties and LA-ICP-MS Geochemistry in Ore Genesis and Exploration”.
The chemistry of pyrite represents a potentially promising new frontier for the research and exploration of different types of ore deposits. Pyrite is an additional source of high-tech (e.g. Co, Tl) and toxic elements (e.g. As, Sb, Te), or can provide a vector for ore deposit exploration and targeting. The application of pyrite in the characterization of ore deposits and exploration vectoring requires the use of progressive modern methods like LA-ICP-MS technology in the field of ore geology. The trace elements and the study of their isotopes is key to understanding ore fluid sources, temperature of deposition and their local alteration and global evolution. Interesting research on the crystal form of pyrite, paragenetic sequences of different pyrite types, and their evolution during hydrothermal and metamorphic events has been a focus of many studies in the last century. The development of LA-ICP-MS trace element mapping of pyrite aggregates has revolutionized our understanding of metal-sulfide paragenesis and is becoming a key technique in ore deposit genesis and geometallurgy.
This Special Issue invites contributions that deal with research into pyrite varieties, including modern exploration vectoring techniques and geometallugy. Studies on the range of ore systems is welcome, including: VHMS, porphyry copper, IOCG, stratiform zinc–lead–silver, MVT zinc, stratiform copper, Carlin-type gold, Witwatersrand-type gold, orogenic gold and other ore deposits. We are inviting contributions on high-resolution and new techniques to explore and characterize the mineralogy and geochemistry of strategic and critical metals like Se, Co, Ni, Te, Au, Ag and PGE concentrated in the pyrite of ore deposits. The LA-ICP-MS study could be useful for the detection of gold and other mineral micro-inclusions and substitution forms in pyrite. These and other techniques may be also used to characterize the physical and chemical parameters of pyrite deposition and deformation. We hope that new studies may reveal the use of pyrite chemistry as a geothermometer and geofugometer.
Contributions on genetic/evolutionary models of ore deposits based on pyrite compositions are also welcome. We especially welcome contributions on the comparison of trace elements and their isotopes in the different genetic origins of pyrite, including hydrothermal, hydrothermal sedimentary, biogenic, diagenetic and metamorphic varieties. We also welcome any new data on toxic trace element (e.g., Tl, As, Sb, Hg, Bi, Mn) concentration and distribution in pyrite to elaborate new criteria for the assessment and prediction of the hazards and risks associated with ore deposit exploitation. The reconstruction of global trace element evolution is another key point for the characterization of the formation of ore deposits. Mid-ocean ridges and back-arc ridges containing areas with hydrothermal activity and black smokers are important sites for the formation of a large variety of pyrite. The role of microorganisms in the formation of pyrite could also be a contribution to this Special Issue. The correlation of conductivity and trace element concentration in pyrite is another area of interest that impacts on the geophysical response of pyrite and geometallurgical recovery.
We look forward to hearing from you.
