Introduction
I am a Sedimentologist currently pursuing post-doctoral research at the University of Gottingën, Germany funded by the Alexander von Humboldt Foundation. My current research focusses on the provenance of Meso-cenozoic sedimentary rocks in the Kutch Basin (India) and its implications on paleogeography and paleotectonics. I am interested in petrography, geochemistry, geochronology and mineral chemistry as tools for provenance analysis.

This paper investigates the provenance of Middle Jurassic to Early Cretaceous sediments in the Kutch basin of western India on the basis of mineralogical investigations of sandstones composition (Quartz-Feldspar-Lithic fragment - QFL plot), Zircon-Tourmaline-Rutile ZTR index and mineral chemistry of heavy detrital minerals of the framework. The stu...
Detrital zircon and monazite dating of clastic rocks in the Mesozoic Kutch Basin at the western continental margin of India reveals predominant sediment derivation from rocks of Neoproterozoic Pan-African orogeny, followed by those of Cambro-Ordovician Bhimphedian (or Kurgiakh) orogeny and 850–1000 Ma rocks, with subordinate input from rocks of 700...
An integrated approach involving Sr–Nd isotope, trace and rare earth element analyses tracks multiple sources of the Mesozoic sediments of the Kutch Basin at the western continental margin of India. High (87Sr/86Sr)t (ratio at time of deposition), negative εNd and high concentrations of large-ion lithophile elements (LILEs) indicate the upper conti...
Petrography and geochemistry of the Mesozoic sedimentary rocks of the Kutch Basin in western India reveal the predominance of felsic source rocks. Single‐grain chemistry of the detrital heavy minerals in these sediments refines the existing provenance interpretations by incorporating additional data related to source lithology. The study presents i...
The Kutch Basin of western India preserves Mesozoic sedimentary rocks deposited during the breakup and northward drift of the Indian subcontinent from Gondwana. These Middle Jurassic to Lower Cretaceous rocks deposited in a shallow-marine-deltaic environment. Internally, this rift basin is subdivided into three sub-basins-Kutch Mainland, Pachchham...
Based on integration of field, petrographic and heavy mineral chemical data, this study highlights the source and tectonic setting of the Mesozoic sandstones of Kutch, Saurashtra, Narmada and Cambay basins at the western margin of India, formed by the progressive splitting of the eastern Gondwanaland. The Kutch Basin is dominated by arkosic sandsto...

Detailed petrographical and geochemical investigations of the Andaman Flysch provide distinct yet contrasting provenance and tectonic setting in different parts of the arc-parallel, uplifted subduction complex. Petrographical and geochemical data from multiple sections in North, Middle and South Andaman Islands highlight the spatial variation in th...
