| Abstract: | Several natural biotite samples were studied by M.E., electron microprobe and XRD. The M.E. parameters allow to group them
as oxybiotites, normal biotites, chloritized biotites and muscovitized biotites. Mechanisms of oxybiotite formation and processes
undergone by the rocks are discussed. |
