Comparing the XRD patterns of mixtures containing CaCO3, how can I just roughly prove that one sample contains more aragonite than another one?

I have the XRD patterns of two samples which mainly contains calcite and aragonite (S1 and S2, see the attachments). How can I just roughly say that S2 has more amount of aragonite than S1?

Whenever you set up, specimen height, data sampling rate and particle size is very important and is related to the wavelength of generated wave for dynamic measurement.

There are also some electronic solutions available to reduce the noise during signals analysis
