reported [40], chlorites with higher Fe/(Fe + Mg) values (>0.5) would be chamosite and those with lower values (<0.5) would be clinochlore. Assuming that the absorption coefficients for the two hydroxy combination bands are similar, it is possible to distinguish different chlorites using their Fe/(Fe + Mg) values.

Feldspars (plagioclase and K-feldspar) and chlorite (clinochlore and daphnite) are predominantly dissolved (anorthite will be excluded from discussion because it was added to fit the low concentration of Ca).
The samples also contained a small amount of microcline (9%), calcite (9%), and clinochlore (8%).
The XRD spectrum for Talc identified both talc and clinochlore, as well as potentially a small amount of quartz.
It is a white to reddish-brown coarse-grained rock composed of calcite, dolomite, Ti-clinohumite, forsterite, diopside, accessory clinochlore, muscovite, fluorapatite and shining flakes of graphite.
Results of X-ray diffraction analysis of 52 stratified samples collected between 58-18 m indicated a mineralogical composition consisting mostly of quartz, muscovite, albite, clinochlore, calcite, and orthoclase (details in Giudice 2005; Dickinson 2008).
After the analyses, the soil minerals found were: quartz, calcite, sanidine, albite, nontronite, muscovite, montmorillonite, hematite, faujasite, dolomite, microcline, anorthite, anorthoclase, clinochlore and epidote.
The X-ray diffraction pattern (Figure 2b) shows the presence of clinochlore (6.3%), a typical mineral of some metamorphic rocks.
The heated and raw bentonites are composed of quartz, illite, montmorillonite, and clinochlore. Moreover, the heated bentonite seems to be relatively less crystalline than the corresponding raw form.
Origin of Constituting Minerals in Lithofacies of the Hangu Formation Lithofacies-I (laterite / bauxite / kaolinite): The petrographic results show that the principal clay minerals include kaolinite (50-65 (Percent) , boehmite (40-50 (Percent) , gibbsite (upto 30 (Percent) , neoformed clay (chamosite upto15 (Percent) and iron rich clay (glauconite 9-15 (Percent) alongwith nacrite / clinochlore (upto 85 (Percent) at Kalra Wahan) and chlorite (upto 5 (Percent) .
According to the XRD analyses, a Patan clay sample contains mainly muscovite and quartz phases, while a Thimi clay sample contains muscovite, quartz, albite and clinochlore phases.
