appendix.pdf provides a two chemical analyses and symmetry analyses of these minerals

 

actinolite.txt is a tab delimited text of the merged spectra shown in Figure 4a.  The left column is the frequency in wavenumbers. The right column is the absorbance (based on natural logarithm).  The thickness is near 1 micron, but not well constrained.  Actinolite.pdf is a graph of these data.

 

sapphirine.txt is a tab delimited text of the merged spectra shown in Figure 4b.  The left column is the frequency in wavenumbers. The right column is the absorbance (based on natural logarithm).  The thickness is near 1 micron, but not well constrained.  sapphirine.pdf is a graph of these data.

 

brucite1.0.txt is a tab delimited text of the merged spectra shown in Figure 2a, with fringes and artifacts removed, but limited to 1800 cm-1.  The left column is the frequency in wavenumbers. The right column is the absorbance (based on natural logarithm).  The thickness is 0.8 to 1.2 microns.  brucite.pdf is a graph of these data.

 

tremmerge.txt is a tab delimited text of the merged mid and far-IR spectra shown in Figure 2b, with fringes and artifacts removed.  The left column is the frequency in wavenumbers. The right column is the absorbance (based on natural logarithm).  The thickness is 0.62 microns, and the sample is from Canaan.  Tremolite.pdf is a graph of these data. Tremolitefullrang.txt and tremolitefullrang.pdf show the entire range of Figure 2b, formatted as above.

 

lizardite0.50.txt is a tab delimited text of the merged mid- and far-IR spectra shown in Figure 2c, with fringes and artifacts removed.  The left column is the frequency in wavenumbers. The right column is the absorbance (based on natural logarithm).  The thickness is 0.5 microns.  lizardite.pdf is a graph of these data.

 

talc0.41.txt is a tab delimited text of the merged mid- and far-IR spectra shown in Figure 2d, with fringes and artifacts removed.  The left column is the frequency in wavenumbers. The right column is the absorbance (based on natural logarithm).  The thickness is 0.42 microns.  talc.pdf is a graph of these data.

 

saponite0.84.txt is a tab delimited text of the merged mid- and far-IR spectra shown for the Scottish sample in Figure 2e, with fringes and artifacts removed.  The left column is the frequency in wavenumbers. The right column is the absorbance (based on natural logarithm).  The thickness is 0.84 microns.  sapponite.pdf is a graph of these data.

 

montm0.75.txt is a tab delimited text of the merged mid- and far-IR spectra shown of the U.K. sample in Figure 2f, with fringes and artifacts removed.  The left column is the frequency in wavenumbers. The right column is the absorbance (based on natural logarithm).  The thickness is 0.75 microns.  montmorillonite.pdf is a graph of these data.
