Hello! I'm Abhinav Thakur, a final year BS-MS student in the Earth Sciences department at Indian Institute of Science Education & Research (IISER) Kolkata, India. I am hoping to graduate by mid-2021, majoring in Geological Sciences. Currently, I am working on my MS project under the guidance of Prof. Sukanta Dey, investigating the petrogenetic evolution of the ultramafic-mafic rocks and associated volcanics from the Dhanjori basin, in the Singhbhum craton of the Indian Shield, using Isotope Geochemistry and Geochronology.
My research interest lies in incorporating Igneous Petrology and Geochemistry with field based investigations in order to understand the conditions in which magmatic processes influenced the formation, evolution and craton stabilization in our early Earth's crust in the Precambrian supereon. I am also interested in deciphering the time scales of such processes by dating accessory minerals like Zircon using various analytical techniques. In the last few years, as a budding geoscientist, I have worn two different hats:
Crustal Evolution of the Singhbhum Craton: My MS research is exclusively on volcanic rocks, and I maintain an active interest in investigating Precambrian tectonics and magmatism via the geochemistry and geochronology of such volcanic rocks to understand crustal evolution and mantle heterogeneity of the Earth.
Himalayan Tectonics: The Himalayan collision zone tectonics between the Indian and the Eurasian plates act as a very distinct example and a typical terrane to observe and understand one of the very extensive and important events of the Cenozoic orogeny. It represents one of the most challenging settings which in the past have excited many researchers to study this excellent field laboratory showing continent-continent collision. I am interested in testing the two different models that explain the formation of the Main Central Thrust system in the Himalayas, ie. Channel Flow model and Thrust-Wedge Taper model. The important question to address here is that, whether channel flow and thrust-wedge taper models are mutually exclusive or whether they represent a continuum of deformation in time and/or space within a single collisional system. Also, recently there have been controversies regarding the mode of origin of the Main Central Thrust Zone, either as a Paleoproterzoic magmatic arc or rift setting. Such questions are of crucial importance for explaining the evolution of the Himalayan orogen and, by extension, for understanding the evolution of Earth’s many continent-continent collision zones.
In order to further furnish my understanding of the process of orogenesis, I spent the next four summers (2016-2019), doing field work at various parts of the Himalaya in India, the Julian Alps in Slovenia and the Bükk mountains in the Inner Western Carpathians of Hungary. Details of these and other projects can be found here.
My curriculum vitae (CV) can be downloaded from here.
When I am not in the field or gazing at Zircon grains in the lab, I could be found climbing a nearby mountainView of Dhauladhar range from my window in the Himalayas, listening to live music or learning new riffs on my guitar.
Here are some of my favourite pictures of beautiful Zircon crystals in CL from the Higher Himalayan Crystallines:
