I would like to know the Zr/Ti ratio present in mud flat sediments. Is there any world average or a range? I'm reading (from "Dellwig, O., Hinrichs, J., Hild, A., Brumsack, H.-J. (2000). Changing sedimentation in tidal flat sediments of the southern North Sea from the Holocene to the present: a geochemical approach. Journal of Sea Research, 44: 195-208") that this ratio is different for present and Holocene sediments of mud flats. The Zr/Ti ratio reported in this paper for recent sediments is 0.25 and for heavy minerals it is 0.48. We obtain a value of around 50 for recent sediments of east coast of India. I would like to clarify that. Any information on sea level fluctuations along east coast of India is also welcome.
A ratio of 50 would mean far more Zr than TiO2 in your samples.
Are you sure you have done the correct calculations?
Be sure to express both elements in the same units: ppm in the example of Dellwig.
Thus multiply the % TiO2 content with 10000 and divide it by 1.668, the oxide to element ratio.
Yes, I made a mistake in the calculation and corrected it. Thank you very much for pointing it out.
The ratio would depend on source area composition. For example, if the mudflat sediments are derived from felsic sources, the ratios would be different from those derived from mafic sources.
