To determine these features, in addition to mineralogical, petrographical, and chemical analyses, Mössbauer analysis was performed.
Using
Mössbauer analysis, the origin of iron was investigated
for the chlorite-bearing talc sample (E-3), which has high
talc content. Figure 5 shows the Mössbauer spectrum of
the talc at room temperature (approximately 300 K). It
should be noted that the isomer shift (IS) is the shift of the
centroid of the spectrum from zero velocity and is given
