The collision between the Indian and Eurasian continents creates one of the largest orogens, the Tibetan-Himalayan orogen, worldwide [1].

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.

The most noticeable changes are related to the maximum Moho depths in central Tibet and less pronounced contours of the crustal thickness between orogens and sedimentary basins.

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.

This eon of rocks, (with high-grade metamorphic belts and intrusive rocks also referred to as 'orogens') is an important host to some of Australia's largest mineral deposits.
