Abstract: | Lower Gondwana coal from Garu-Gensi area in the West Siang district of Arunachal Pradesh in the Eastern Himalayas have been
characterized with respect to their maceral constituents, mineral matter, ash composition, sulphurand trace-element contents.
These are low-rank bituminous coals (V0 = 0.64) and their vitrinite content is about 60%. A first hand data with respect to twenty one trace-elements are reported.
Our data indicate that these Lower Gondwana coals of extra-peninsular region are richer in terms of their trace-element content
when compared with their counter parts of peninsular India. |
