Geochemical analysis reveals nickel, chromium, and zinc mineralization in metamorphic migmatites, indicating viable economic and industrial mineral potential.
Key Points
To evaluate the petrogenesis, structural deformation history, and economic mineral potential of migmatitic rocks.
Conducted field structural mapping to measure planar fabrics and deformational episodes.
Performed thin-section petrographic analysis and XRF geochemical profiling on representative rock groups.
Applied Sawyer's morphological classification and generated elemental concentration maps.
Identified two major deformational episodes (D1, D2) with a dominant NNE/SSW structural trend and high-grade mineral assemblages including K-feldspar, biotite, quartz, zircon, and garnet.
Determined that the migmatites originated through partial melting and metamorphic differentiation of tholeiitic to calc-alkaline mafic protoliths during the Pan-African orogeny.
Mapped anomalous concentrations indicating clear mineralization potential for nickel, chromium, zinc, and related industrial minerals.
