Evolution and Resetting of the Fluids in Manikaran Quartzite, Himachal Pradesh: Application to Burial and Recrystallization

Primary aqueous fluid inclusions trapped in Manikaran Quartzite suggest a depth of burial about 4 to 7 km and entrapment temperature from 67 to 146°C. The later thrust-related recrystallization occurred in H₂O-CO₂ fluid regime under greenschist facies conditions. This event also resulted in thermal resetting of some aqueous inclusions trapped in original grains.
