      This will result in the preservation of mineral deposits such as ophiolitic Cr and VMS deposits that had already formed in the intraocean environment accreted to the continental margin Arc reversal is a feature in some arc–continent collisions, and this effectively turns passive continental margins into sub continental subduction margins with an active continental arc

      Determining the likelihood of preservation will involve an assessment of the pressure and temperature conditions associated with deposit formation (eg IOCGs, ISCGs, Pb–Zn, Au, Ag), which will be crossreferenced against the pressure and temperature conditions preserved before and after the timing window for mineralisation, and against basement topography

  • A scaleintegrated exploration model for orogenic

      For all mineral deposits, preservation is as important as formation in dictating the distribution of deposits through time (Groves et al, 2005b) For many mineral deposit types formed at shallow crustal levels, uplift, exhumation and erosion dictate a relatively short geological lifetime

    The required concentration factor, which is defined as the ratio of the average concentration of an element in a mineable mineral deposit to its average crustal abundance, is highly variable and depends not only on the particular element but also on the type of deposit The concentration factors range from about 5–10 for geochemically abundant elements (eg, aluminum and iron) to about 100–1,000 for

  • Geodynamic settings of mineral deposit systems

      Mineral deposits represent extraordinary metal concentrations that form by magmatic, magmatic–hydrothermal or hydrothermal processes in geodynamic environments typified by anomalously high thermal and/or mechanical energy near plate boundaries As they require the conjunction of specific environmental conditions to form, particular mineral deposit types tend to occupy specific geodynamic
