Thanks Jafar and Kenneth sir, samples are under analysis. Before getting the result i would like to know the possibilities and their relation, so that i will be in position to differentiate the actual scenario.

After getting the result i will share with you. Once again thank you...

Dear Mr. Tripathi,

why do you take refuge to sulfur isotopes ? First make an attempt using geological methods such as sedimentological ones, than go into sedimentary-mineralogy (heavy and light minerals, phyllosilicates). Also the major and minor elements offer a lot in terms of recognition of the paleo-environment. There exists a wealth of papers. Do not saddle the horse from the tail and follow straightforward the common way of geoscientific work.

This is based on almost 40 years working in the geoscientific business.

Dear Mr. Tripathy,

Since, sulphur isotope ratio depends on the oxidation/reduction status of the sediments. Therefore, oxydation status of the sediments must be worked out first based on heavy metal analysis and cerium anomaly determination etc. Try with geological and geochemical methods first and then correlate your findings with the evaluated sulphur isotope ratio.

Thank you all for your valuable answer, basically i am dealing with micropaleontological samples and i got evidence of intertidal microfauna within clay. Presently study area is  below 20m water depth. As per your suggestions i will try to analyse few samples.
