Dear MSA, Can anyone point me to papers and/or theses that report data for the relationship between temperature and actinolite chemistry? I'm specifically interested in how the Fe/Mg ratio correlates with temperature for hydrothermal actinolite. Thanks, Adam ____________________________________________________________ Adam C.
