Executive Summary : | The project titled "Petrological and Geochronological Investigations of sandmata Granulites, NW India: Insights into the Deep Crustal Characteristics" aims to conduct a comprehensive study on the petrological characteristics and temporal constraints of the sandmata granulites. The sandmata granulites are high-grade metamorphic rocks that have undergone intense pressure and temperature conditions deep within the Earth's crust, resulting in unique mineral assemblages and textures. The identified research gap in the proposed study area is due to the fact that there is scantiness of geochronological and geochemical data to predict a sustainable geodynamic model and tectonometamorphic evolution of the sandmata Granulites. By utilizing advanced analytical techniques and geochronological methods, this research endeavor seeks to unravel the complexities of the sandmata granulites, provide insights into their petrogenesis, and contribute to our understanding of the deep crustal evolution in this region.
The project will commence with detailed fieldwork, including geological mapping and sample collection from representative outcrops of the sandmata granulites. Careful selection of samples will ensure a comprehensive analysis of the petrological characteristics. Through detailed petrographic examination, mineralogical analysis, and microscopy techniques, the project aims to identify and describe the mineral assemblages, textures, and relationships within the exposed granulites. This investigation will shed light on the processes and conditions that led to the formation of these rocks and their subsequent exhumation.
Geochronological analyses using radiometric dating methods like U-Pb and Ar-Ar dating will determine the ages of mineral phases in the sandmata granulites, establishing the time frame of the metamorphic events. This provides a temporal framework for deep crustal evolution. Additionally, the project aims to reconstruct metamorphic conditions using thermodynamic modeling and geothermobarometry. By estimating pressure and temperature conditions during metamorphism, combined with geochronological data, insights into geological processes and tectonic history impacting granulite formation and evolution will be gained.
The project will provide a detailed petrological characterization, geochemical insights, and geochronological constraints for the sandmata granulites. The outcomes will enhance our understanding of deep crustal evolution, tectonic processes, and the geological history of the region. Dissemination through publications and presentations will ensure widespread benefit to the scientific community. Advancements in petrology, geochemistry, and temporal constraints will contribute to the broader field of Earth sciences. |
