- Sample Description
- Fine grained rock coating. Visual estimate of grain size. IMAGE_OF_SAMPLE: NO PHOTO
- XRD Analysis
- Muscovite-2M1(minor), calcite(trace), quartz(minor), microcline(minor), albite(minor). **Some goethites are XRD amorphous and lack of goethite detection in this case may mean that this sample is also XRD amorphous (see:Swayze, G.A., K.S. Smith, R.N. Clark, S.J., Sutley, R.M. Pearson, J.S. Vance, P.L. Hageman, P.H. Briggs, A.L. Meier, M.J. Singleton, and S.
