Abstract/NotesAbstract
About 52% of the samples of Cox's Bazar beach contain six textural types of hematite-ilmenite exsolutions,the commonest (∼83%) being the seriate type. Hemo-ilmenite with greater ilmenite contnet exsolves in a process of continuous exsolution mechanism, whereas more hematiterich phases (very common) exsolve discontinuously. The hemo-ilmenites (IIm45 Hem55 to IIm75 Hem25) are ferrimagnetic in nature. Modal analysis has indicated the percentages of pure ilmenite (exsolved + unexsolved type) and hematite (exsolved, both host and guest) to be 73.74% and 26.26% respectively. This result also corroborates with X-ray, Mossbauer and chemical analyses.
