Abstract:
|
Formations of endogenous ore deposits and mineralization are widely distributed in
Vietnam. Detailed studies allow for distinguishing 30 ore formations representing 9 groups of
mineral raw - materials: Cr, Ti, Fe, Sn - W, Mo, Pb - Zn, Au, Sb - Hg. Three of presented formations
are of magmatic affiliation, one is pegmatitic, three others belong to skarn mineralization and the
remaining ones are of hydrothermal - volcanic and controversial origin. Three metallogenic epochs
can be distinguished: Proterozoic, Palaeozoic and Mesozoic - Cainozoic. Taking into consideration
the recent structural data and economic importance along with the geochemical units can be
distinguished in Vietnam: 1. Sialic - mafic Viet Bac; 2. Mafic Tay Bac; 3. Sialic Truong Son; 4. Mafic -
metamorphic Kontum; 5. Sialic - alkaline Dalat - Nam Bo. |
