Summary

The mineral assemblages of the pelitic rocks of the chlorite and biotite zones of the Kumaon Himalaya are characteristic of the quartz–albite–muscovite–cnlorite and quartz–albite–epidote–biotite sub-facies of the greenschist facies. The appearance of garnet in the sericite–chlorite pelites is due to bulk composition which plots above the muscovite–chlorite join in the AKF diagram. The variation in composition of coexisting sericite and chlorite is related to bulk composition of the rock.
