Antimony deposits are frequently assigned to orogenic gold systems, because of similar characteristics, such as paragenesis, alteration, or tectono-metamorphic environments. The genetic models of antimony mineralisation, however, seem to differ from the classical one of orogenic gold deposits. Magmatism and overlying volcanic plumbing system are proposed to play a key-role in the mobilisation and concentration of Sb and related metals and metalloids, with the interactions between magmas and surrounding sediments possibly playing a role in the mineralising processes, by assimilation or devolatilisation of sediments. More research about Sb deposits is therefore required to better constrain the genetic processes leading to mineralisation. This may contribute to future discoveries of antimony resources that are critical in various applications in our technological societies.

This session welcomes all presentations dealing with antimony and frequently associated elements, such as Au, Hg, As, W. In particular, we invite contributions on the relationships with magmatism, volcanism, and geothermal fluid circulation, from ore to geodynamic scale.
