| Abstract: | A new occurrence of (syenite-hosted) Vanadium bearing titaniferous magnetite ore body has been reported from Ganjang (26°09′35″
N: 93°20′ E), Karbi-Anglong, Northeastern India. The magnetite ore bodies have lumpy and sporadic occurrences within the host
syenite pluton intrusive into gneissic country rocks. Ore microscopic studies reveal that magnetite is often associated with
haematite and ilmenite depicting different textural patterns. Critical consideration of several elemental patterns suggests
magmatic differentiation to be main ore-forming process. The ore body is suggested to have been formed as late stage segregation
from a differentiating alkaline magma in a fluid enriched milieu. |
