crustal evolution (under Prep)
Highlights of major Scientific contributions by Prof. T. Ahmad:
Geochemical and isotopic studied the Precambrian mafic magmatic rocks form
the northern India shield (Aravalli and Central India regions: Ahmad and Rajamain,
1991; Ahmad and Tarney 1994; Kumar and Ahmad 2007; Ahmad and Jayananda 2008;
Ahmad et al. 2008a,b,c; 2009) and those from the Lesser Himalaya helped in
understanding the Precambrian lithospheric extension and opening of Aravalli and Lesser
Himalayan rift basins (Ahmad and Bhat 1987; Ahmad and Tarney 1991; Ahmad 2008).
Similar studies on the Cretaceous magmatic rock of the Indus and Shyok Suture Zones,
Ladakh helped in understanding of the closure of the Neo-Tethyan Ocean by northward
subduction of the Neo-Tethyan ocean floor under the Eurasian plate (Ahmad et al., 1996,
1998, 2005; 2008).
Nd-isotopic profiling across major structural /metamorphic units indicate that the
Vaikrita Thrust is the ‘real’ Main Central Thrust (MCT). Nd model ages and epsilon Nd
values indicate that the high grade Vaikrita Group rocks have much younger mantle
extraction ages compared to the Lesser Himalayan sequences. Thus the Vaikrita Group is
not the basement for the Lesser Himalayan sequences, rather the former could be
basement for the Tethyan Sedimentary Sequences (Ahmad et al., 1999, 2000).
Separated zircon crystals from Ladakh and Karakoram batholiths display zoned
zircon crystals typically observed in igneous rocks. U-Pb zircon SHRIMP ages obtained
for the Khardun La and Chang La top samples is circa 58 Ma. A Karakoram Batholith
sample near Tangste Gompa gives an age of circa 32 Ma. One zircon grain from this
sample gave a late Permian age, and this may indicate the involvement of older crust in
the batholith. One leucocratic granitic dyke sheet sampled between Darbuk and Shyok
villages has a mixture of zircon crystals that gave a range of ages between 15 Ma and 97
Ma. Several grains gave ages ranging between 250 – 970 Ma. These older ages may
indicate that older crust was involved in the generation of part of the Karakoram
Batholith (possibly the southern portion of the Tibetan slab?). Recent suggestions that
collision was as late as 35 Ma may need serious consideration in the light of magmatic
zircon ages of 32-36 Ma by Prof. Ahmad and his co-workers from ANU (Ahmad et al.
2008).
Recent and ongoing studies by Prof. Ahmad in the Central Indian Tectonic Zone
indicate major role of bi-modal volcanism during Proterozoic Crustal evolution in the
Central Indian Shield (Ahmad et al., 2009). Sm-Nd and U-Pb zircon age data from the
Amgaon-Tirodi basement rocks indicate first extraction of the crust from mantle started
during Archean (~3100 Ma) and the first remobilized granitic melt were generated during
early Proterozoic (~2400Ma).
