57Fe Mössbauer spectroscopy study of organic rich sediment (source rocks) from test well K-263 of Cambay Basin, India

57Fe Mössbauer Spectroscopy study was carried out on the samples collected from different depth interval of a representative well K-263 of the North Cambay basin (India). The results obtained were compared with the basins already studied. Comparison show that general trend of relative distribution of iron containing minerals as a function of depth for well K-263 is more or less similar to that reported for Eastern Krishna Godavari Basin. Interestingly both these basins have similar hydrocarbon prospecting (hence nature of organic content) also. On the other hand we found that distribution pattern of iron minerals of Cambay basin is markedly different from the basins (viz North Sea and Jaisalmer) having different prospecting and organic properties in comparison to Cambay Basin. So some correlation exists between distribution of iron minerals and prospects of a basin.
