Iron-titanium oxide minerals in the high-iron concentration type of basalts in the Deccan traps
The Deccan Trap basalts of Bhopal are high-iron concentration types of tholeiites. Various forms and mode of occurrence is described. The growth of the crystals through stages are discussed. A gradual decrease in the degree of oxidation from the bottom to top flows is noticed. The iron enrichment re...

| Tartalmi kivonat: | The Deccan Trap basalts of Bhopal are high-iron concentration types of tholeiites. Various forms and mode of occurrence is described. The growth of the crystals through stages are discussed. A gradual decrease in the degree of oxidation from the bottom to top flows is noticed. The iron enrichment remaining constant the oxidation ratio show a gradual rise. Studies in reflected light under the ore microscope show the presence of the following types of the iron ores; magnetite, ilmenite, titanomagnetite and scarcely hematite. An account of the paragenesis of these opaques is presented. |
