High content ofmonocrystalline quartz (DMG: 28.21%; MF: 30.7), and higher Si02/A1203 ratios in sandstones (DMG: 9.86; MF: 11.98) also indicate high maturity ofsandstones due to recycling of source terrain in collision orogens
. High Cr/Ni (DMG: 5.23; MF: 6.17) and moderate CrN (DMG: 3.96; MF: 3.88) ratios suggest significant contributions from mafic and ultramafic detritus derived from Muslim Bagh-Zhob Ophiolite.
However, dominance of lithic fragments in some of the samples indicates that there may have been a sediment influx from proximal Neoproterozoic to Late Cambrian orogens
. Based on 40Ar/39Ar geochronology, sediments may have been derived from various sources.
