Oxidation-reduction
state of magma in general and graniotide in particular are important for
determining the metallogene potential for magma bodies. Oxidation-reduction
conditions help to explain geochemical specialization not only at the content
level, but also on the geochemical behavior of the elements.
For
the first time, research primary inclusions by Thermobarogeochemical method
(RAMAN equipment) has identified that Bến Tuần block’s granite has
oxidation state (CO2-rich primary inclusions). This condition is not
favorable for the metallogenic specalization of Sn, but it can be advantageous
to move Mo and Cu from magma to ore solution.
Keywords: oxidation - reduction, Bến Tuần,
metalogical potential.
